FEM for Smart Energy/Advanced Metering Infrastructure & ISM Band Applications
The RFFM6403 is a highly-integrated front-end module (FEM) for smart energy/advanced metering infrastructure (AMI) applications. The single-chip RFFM6403 FEM reduces customer design time and speeds customer time-to-market for portable battery-powered equipment, general 433-/470-MHz ISM-band systems, and smart energy/AMI applications operating in the 405-to-475-MHz frequency range.
The feature-rich RFFM6403 integrates a transmit high-power path with a 30.5-dBm PA and Tx harmonic output filtering a transmit bypass through path with Tx harmonic output filtering, and a receive path with a low-noise amplifier (LNA) with bypass mode. The FEM also features a low insertion loss/high-isolation SP3T switch and separate Rx/Tx 50-Ω ports, which simplifies matching and provides input and output signals for both the Tx and Rx paths.
The RFFM6403 is designed for AMI systems operating with high-efficiency requirements and a minimum output power of 30 dBm. In the receive path, the Rx chain provides 16 dB of typical gain with only 5 mA of current and a 1.7-dB noise figure. The FEM’s small form factor (6 mm × 6 mm × 1 mm) minimizes product footprint and reduces the external component count and associated assembly costs.

Pressure Sensors for Flow Measurement in Bypass Configuration
The SDP601 and SDP611 sensors are differential pressure sensors specifically calibrated to measure mass flow in a bypass configuration. A bypass configuration is well suited for applications where individually adapted flow channels are necessary or where small differential pressures must be measured with high precision (e.g., HVAC applications, which often involve large flow volume measurement).
Bypass configurations use an orifice or a linear-flow restrictor to generate a differential pressure in a flow channel. This pressure is measured over the orifice or the linear flow component. The difference between the pressures before and after the orifice correlates to the volumetric flow in the channel, depending on the specific characteristics of the flow restriction component. Therefore, the mass flow can be calculated from the measured pressure drop (i.e., differential pressure) over the orifice.
The SDP601 and SDP611 sensors expand Sensirion’s product range of digital differential pressure sensors in the SDP600 series. Along with the other products in this series, these sensors provide a digital I2C output and are fully calibrated and temperature compensated. Like all devices in the SDP600 series, the SDP6x1 sensors are available in two versions. The SDP601 is designed for direct threaded connection to a pressure manifold with O-ring sealing. The SDP611 is designed for tube connection.

Single-Board Retrocomputer
The CGCOLORMAX is a single-board retrocomputer that supports add-on Arduino Shields and runs a modern implementation of the BASIC programming language. The board has connections for color video (i.e., video graphics array) output and a PS/2 keyboard input. An SD card socket on the front of the board provides the “floppy drive” for program and data storage.
A stereo music synthesizer, an Arduino Shield interface, and a battery-backed clock are included on The CGCOLORMAX. Hardware interfacing is available as 20 I/O lines on the rear connector and 20 lines on the Arduino Shield connector. This versatile design enables you to easily interface to serial, SPI, I2C, 1-wire, and other circuits.
The CGCOLORMAX also includes a bootloader that enables firmware updating and comes preloaded with BASIC. The board can be tethered to a PC/Mac via a USB cable and programmed via a serial terminal. The USB connection can also provide power to the board.
The CGCOLORMAX can operate as a stand-alone computer by supporting a keyboard and a VGA monitor. The board can be powered by any 8-to-18-V AC or DC power supply. The default BASIC program can be automatically loaded from internal or SD card memory.

Optimized Compiler with Advanced Debug Capabilities
A complete integration with the Eclipse IDE—IAR Systems’s integrated development environment (IDE)—is available for IAR Embedded Workbench for ARM, the high-performance development tool suite. With this integration, IAR offers Eclipse support as an alternative to the IAR Embedded Workbench IDE, which enables its customers to use its build tools and debugger within the Eclipse IDE.
While the proprietary IAR Embedded Workbench IDE is tailor-made for embedded development, intuitive, and easy-to-use, the open-source Eclipse IDE provides flexibility through its extensible framework and its ability to interoperate with a large ecosystem of supplementary tools.
The full integration of the IAR C-SPY debugger replaces the GDB-based debugger that is standard with Eclipse, and enables IAR Systems’ debug technology to be fully exploited from within the Eclipse IDE. C-SPY’s debug functionality includes a timeline window that graphically correlates visualizations of interrupt logs, data logs, power samples, and user-defined events plotted against time. C-SPY supports ARM’s Embedded Trace Macrocell (ETM) and its Embedded Trace Buffer (ETB). Power profiling enables fine-tuning of an application’s power consumption, and the C-SPY Trace window displays detailed trace data.
In addition to all standard Eclipse CDT (C/C++ development tooling) functionality, the integration enables additional features (e.g., project import functionality, stepping on function call level, and complex code and data breakpoints).
