技术问答

These days, networks connect many edge devices such as home appliances, buildings, and factories all over the world. The number of IoT devices is increasing year by year, especially in healthcare, consumer, and industrial applications. These IoT devices often have limited size, and not only internal components but also the main processor are required to be miniaturized. The RA2E2 ultra-compact Arm MCU was designed specifically for these small, connected IoT devices and now the new RA2E2 fast prototyping board will help decrease your solution development time to get to market faster.

What is RA2E2?

The ultra-compact RA2E2 MCU has optimized functionality and memory capacity that can contribute to cost-sensitive applications. RA2E2 has a 1.84 mm x 1.87 mm 16-pin WLCSP package and supports 20-pin and 24-pin QFN, as well. These small size packages enable designers to use them in space-constrained designs without PCB area concerns.

Ultra-low power consumption

RA2E2 achieves the lowest power consumption in the 32-bit MCU class, delivering an operating current of 81 μA / MHz and software standby current of 200 nA with fast wakeup. Software standby mode reduces power consumption to a minimum level by shutting down the CPU, most internal peripherals, and oscillators. Furthermore, it is possible to return from software standby mode at high speed in less than 7.3 μs. The RA2E2 has flexible power architecture and power modes to achieve lower average power for multiple applications.

Optimized functions

Optimizing peripheral functions for low-power operation helps contribute to a reasonable system cost. 32-bit low-power AGT and I³C are the RA2 series' first such functions and the operating temperature range is extended from -40 to +125℃. I³C is a serial communication interface with improved I2C functions, performance, and power consumption, and is a new standard expected to be applied to various applications such as sensor control and wearable devices.

What is a Fast Prototyping Board?

The RA2E2 fast prototyping board, allows you to quickly and easily evaluate RA2E2 at a reasonable cost. It has a built-in E2 emulator Lite so you can debug programs directly without an extra emulator. It also has Arduino Uno and Pmod™ interfaces which can extend the evaluation environment. The FPB is the size of a business card (5.3 cm x 8.5 cm), so you can easily evaluate it.

To experience the excellent advantages of RA2E2 and the FPB, RENESAS has created sample programs that can immediately measure air quality with the Renesas ZMOD4410 gas sensor module and room temperature and humidity with the HS3001 temperature/humidity sensor module. These sample programs show how to connect the sensor module and FPB with I³C via the Pmod connector, and you can evaluate the advantages of I³C, such as power consumption and wire-saving.
