CAN Flexible Data-Rate Transceiver Family

Microchip Technology recently launched the MCP2561/2FD family of CAN Flexible Data-Rate (FD) transceivers. As an interface between a CAN controller and the physical two-wire CAN bus, the transceivers work for both the CAN and CAN FD protocols. Thus, the family helps automotive and industrial manufacturers with current CAN communication needs and provides a path for newer CAN FD networks.Microchip MCP25612FD CAN FD transceivers

In-vehicle networking growth continues to be driven by the need for electronic monitoring and control. As application features in power train, body and convenience, diagnostics and safety increase, more Electronic Control Units (ECUs) are being added to existing CAN buses, causing automotive OEMs to become bandwidth limited. In addition, the end-of-line programming time for ECUs is on the rise due to more complex application programs and calibration, which raises production line costs. The emerging CAN FD bus protocol solves these issues by increasing the maximum data rate while expanding the data field from 8 data bytes up to 64 data bytes.

With their robustness and industry-leading features, including data rates of up to 8 Mbps, Microchip’s MCP2561/2FD transceivers enable customers to implement and realize the benefits of CAN FD. These new transceivers have one of the industry’s lowest standby current consumption (less than 5 µA typical), helping meet ECU low-power budget requirements. Additionally, these devices support operation in the –40°C to 150°C temperature range, enabling usage in harsh environments.

The new family of MCP2561/2FD CAN FD transceivers is available in eight-pin PDIP, SOIC and 3 × 3 mm DFN (leadless) packages, providing additional design flexibility for space-limited applications. The family also provides two options. The MCP2561FD comes in an 8-pin package and features a SPLIT pin. This SPLIT pin helps to stabilize the common mode in biased split-termination schemes. The MCP2562FD is available in an eight-pin package and features a Vio pin. This Vio pin can be tied to a secondary supply in order to internally level shift the digital I/Os for easy microcontroller interfacing. This is beneficial when a system is using a microcontroller at a VDD less than 5 V (e.g., 1.8 V or 3.3 V), and eliminates the need for an external level translator, decreasing system cost and complexity.

The MCP2561FD and MCP2562FD transceivers are both available now for sampling and volume production in 8-pin PDIP, SOIC and 3 × 3 mm DFN packages, starting at $0.69 each, in 5,000-unit quantities.

New SQI Interface SuperFlash Memory Devices

Microchip Technology recently launched the SST26VF family of 3-V Serial Quad I/O interface (SQI interface) SuperFlash memory devices. Available with 16-, 32- or 64-Mb of memory, the “26 Series” family is manufactured using Microchip’s high-performance CMOS SuperFlash technology.

The SST26VF memory family provides fast erase times due to its use of SuperFlash technology. Sector and block erase commands are completed in just 18 ms, and a full chip erase operation is completed in 35 ms. Competitors’ devices require 10 to 20 s to complete a full chip erase operation, making the SST26VF approximately 400× faster. These fast erase times can provide a significant cost savings to customers, by minimizing the time required for testing and firmware updates, and therefore increasing their manufacturing throughput.Microchip SST26VF

Microchip’s SQI interface is a low pin count, high-speed 104 MHz quad-bit address and data multiplex I/O serial interface, which allows for high data throughput in a small package. This interface enables low-latency execute-in-place (XIP) capability with minimal processor buffer memory, reducing the overall design footprint compared to traditional parallel memory interfaces. The SST26VF family provides faster data throughput than a comparable x16 parallel flash device, without the associated high cost and high pin count of parallel flash. The SQI interface also offers full command-set backward compatibility for the ubiquitous SPI protocol.

Designed for low power consumption, the SST26VF is ideal for energy-efficient embedded systems. Standby current consumption is 15 µA (typical), and the active read current at 104 MHz is 15 mA (typical). The combination of 3-V operation with low power consumption and small-form-factor packaging makes the SST26VF devices an excellent choice for applications such as servers, printers, cloud computing systems, HDTV, Internet gateways, appliances, security systems, and a broad range of embedded systems.

The SST26VF devices also offer 100 years of data retention and device endurance of over 100,000 erase/write cycles. Enhanced safety features include software write protection of individual blocks for flexible data/code protection. In addition, the upper and lower 64 KB of memory are partitioned into smaller, 8-KB sectors that can both read- and write-lock. In addition, the devices include a One-Time Programmable (OTP) 2-KB Secure ID area, consisting of a 64-bit, factory-programmed unique ID and a user-programmable block. These features protect against unauthorized access and malicious read, program and erase intentions. The devices also include a JEDEC-compliant Serial Flash Discoverable Parameter (SFDP) table, which contains identifying information about the functions and capabilities of the SST26VF devices for simpler software design.

The three-member SST26VF family is available now for sampling and volume production in multiple package options, including eight-pin SOIC and SOIJ, 16-pin SOIC, eight-contact WDFN and 24-ball TBGA, as well as in die and wafer form. In 10,000-unit quantities, the 16-Mb SST26VF016B starts at $0.90 each, the 32-Mbit SST26VF032B starts at $1.17 each, and the 64-Mbit SST26VF064B starts at $1.84 each.

New Microcontrollers Feature Advanced Analog & Digital Integration

Microchip Technology recently announced a new family of 8-bit PIC microcontrollers (MCUs) with the PIC16(L)F1769 family, which is the first to offer up to two independent closed-loop channels. This is achieved with the addition of the Programmable Ramp Generator (PRG), which automates slope and ramp compensation, increases stability and efficiencies in hybrid power conversion applications. The PRG provides real-time responses to a system change, without CPU interaction for multiple independent power channels. This allows customers the ability to reduce latency and component counts while improving system efficiency.Microchip PIC16(L)F1769

The PIC16(L)F1769 family includes intelligent analog and digital peripherals, including tristate op-amps, 10-bit ADCs, 5- and 10-bit DACs, 10- and 16-bit PWMs, and high-speed comparators, along with two 100-mA, high-current I/Os. The combination of these integrated peripherals help support the demands of multiple independent closed-loop power channels and system management, while providing an 8-bit platform that simplifies design, enables higher efficiency and increase performance while helping eliminate many discrete components in power-conversion systems.

In addition to power-conversion peripherals, these PIC MCUs have a unique hardware-based LED dimming control function enabled by the interconnections of the Data Signal Modulator (DSM), op amp and 16-bit PWM. The combination of these peripherals creates a LED-dimming engine synchronizing switching control eliminating LED current overshoot and decay. The synchronization of the output switching helps smooth dimming, minimizes color shifting, increases LED life and reduces heat. This family also includes Core Independent Peripherals (CIPs), such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG), and Zero Cross Detect (ZCD). These CIPs take 8-bit PIC MCU performance to a new level, as they are designed to handle tasks with no code or supervision from the CPU to maintain operation, after initial configuration. As a result, they simplify the implementation of complex control systems and give designers the flexibility to innovate. The CLC peripheral allows designers to create custom logic and interconnections specific to their application, reducing interrupt latency, saving code space and adding functionality. The COG peripheral is a powerful waveform generator that can generate complementary waveforms with fine control of key parameters, such as phase, dead-band, blanking, emergency shut-down states, and error-recovery strategies. It provides a cost-effective solution, saving both board space and component cost. The ZCD senses when high voltage AC signal crosses through ground, ideal for TRIAC control functions.

These new 8-bit PIC MCUs provide the capability for multiple independent, closed loop power channels and system management making these products appealing to various power supply, battery management, LED lighting, exterior/interior automotive lighting and general-purpose applications. Along with all these features, the family offers EUSART, I2C/SPI and eXtreme Low Power (XLP) Technology, which are all offered in small form-factor packages, ranging from 14- to 20-pin packages.

The PIC16(L)F1769 family is supported by Microchip’s standard suite of world-class development tools, including the MPLAB ICD 3 (part # DV164035, $199.95) and PICkit 3 (part # PG164130, $47.95) and MPLAB Code Configurator, which is a plug-in for Microchip’s freeMPLAB X IDE provides a graphical method to configure 8-bit systems and peripheral features, and gets you from concept to prototype in minutes by automatically generating efficient and easily modified C code for your application.

The PIC(L)F1764, PIC(L)F1765, PIC16(L)F1768, and PIC(L)F1769 are available now for sampling in 14- and 20-pins in PDIP, SOIC, SSOP, TSSOP, and QFN packages. Pricing for the family starts at $0.87 each, in 10,000-unit quantities.
