Microchip Technology’s new PIC32MX1/2/5 series enables a wide variety of applications, ranging from digital audio to general-purpose embedded control. The microcontroller series offers a robust peripheral set for a wide range of cost-sensitive applications that require complex code and higher feature integration.MicrochipPIC32MX125-starterkit

The microcontrollers feature:

  • Up to 83 DMIPS performance
  • Scalable memory options from 64/8-KB to 512/64-KB flash memory/RAM
  • Integrated CAN2.0B controllers with DeviceNet addressing support and programmable bit rates up to 1 Mbps, along with system RAM for storing up to 1024 messages in 32 buffers.
  •  Four SPI/I2S interfaces
  • A Parallel Master Port (PMP) and capacitive touch sensing hardware
  • A 10-bit, 1-Msps, 48-channel ADC
  • Full-speed USB 2.0 Device/Host/OTG peripheral
  • Four general-purpose direct memory access controllers (DMAs) and two dedicated DMAs on each CAN and USB module

 

Microchip’s MPLAB Harmony software development framework supports the MCUs. You can take advantage of Microchip’s software packages, such as Bluetooth audio development suites, Bluetooth Serial Port Profile library, audio equalizer filter libraries, various Decoders (including AAC, MP3, WMA and SBC), sample-rate conversion libraries, CAN2.0B PLIBs, USB stacks, and graphics libraries.

Microchip’s free MPLAB X IDE, the MPLAB XC32 compiler for PIC32, the MPLAB ICD3 in-circuit debugger, and the MPLAB REAL ICE in-circuit emulation system also support the series.

The PIC32MX1/2/5 Starter Kit costs $69. The new PIC32MX1/2/5 microcontrollers with the 40-MHz/66 DMIPS speed option are available in 64-pin TQFP and QFN packages and 100-pin TQFP packages. The 50-MHz/83 DMIPS speed option for this PIC32MX1/2/5 series is expected to be available starting in late January 2015. Pricing starts at $2.75 each, in 10,000-unit quantities.

New AFEs for Single-Phase Smart Meters & Power Monitoring

Microchip Technology has announced the completion of its MCP391X energy-measurement Analog Front End (AFE) family.  The MCP3919 and MCP3912 integrate three and four channels of 24-bit, delta-sigma ADC, respectively. They have an accuracy of 93.5 dB SINAD, –107-dB THD, and 112-dB SFDR for precise signal acquisition and higher-perforce end products.microchipMCP391Xafe

Microchip also announced two new tools to aid in the development of energy systems using the new AFEs.  The MCP3912 Evaluation Board (part # ADM00499) and MCP3919 Evaluation Board (part # ADM00573) are each available for $129.99.

The MCP3912 and MCP3919 AFEs are both available today for sampling and volume production, with prices starting at $1.84 each in 5,000-unit quantities.  Both AFEs are offered in 28-pin QFN and SSOP packages.

New Digitally Enhanced Power Analog Controllers

Microchip Technology recently announced its latest Digitally Enhanced Power Analog (DEPA) controllers—the MCP19118 and MCP19119—which offer analog PWM control for DC-DC synchronous buck converters up to 40 V with the configurability of a digital microcontroller. MicrochipMCP19118

Interestingly, the devices bring together 40-V operation and PMBus communication interfaces for power-conversion circuit development with an analog control loop that is programmable in the integrated 8-bit PIC core’s firmware.  According to Microchip in a product release, “this integration and flexibility is ideal for power-conversion applications, such as battery-charging, LED-driving, USB Power Delivery, point-of-load and automotive power supplies.”

As expected, Microchip’s MPLAB X, PICkit 3, PICkit serial analyzer, and MPLAB XC8s support the MCP19118/9 DEPA controllers. The MCP19118 and MCP19119 are now available with prices starting at $2.92 each in 5,000-unit quantities.

 

Dev Platform with 2-D Multi-Touch and 3-D Gestures

Microchip Technology recently announced the availability of the 3DTouchPad, which it describes as “a PC peripheral and world’s first Development Platform for 2D multi-touch and 3D gestures.”Microchip_3DTOUCH_7x5_RGB

The 3DTouchPad adds free space gesture recognition to projected-capacitive multi-touch.  Basically, it provides 3-D gesture recognition via Microchip Technology’s GestIC, which provides a detection range of up to 10 cm for 3D gestures, as well as Microchip’s projected-capacitive 2-D multi-touch solution supporting up to 10 touch points and multi-finger surface gestures. Microchip also claims the 2-D multi-touch is enhanced by its new capacitive touch-screen line driver, MTCH652.

The new 3DTouchPad includes: a driverless, out-of-the-box features for Windows7/8.X and OS X, 3D air gestures; advanced multi-touch performance including surface gestures; and a free downloadable GUI and SDK/API package. Possible applications include home automation, remote controls, game controllers, and wearable devices.

The 3DTouchPad costs $99.
