Renesas Electronics EK-RA2A2 Evaluation Kit

Renesas Electronics EK-RA2A2 Evaluation Kit enables users to evaluate the features of the RA2A2 MCU Group effortlessly. This kit helps in developing embedded systems applications using Renesas’ Flexible Software Package (FSP) and e² Studio IDE. The kit contents include an EK-RA2A2 v1 board and Micro USB device cable (type-A male to micro-B male). The users can leverage the extensive onboard features in combination with their preferred ecosystem add-ons to transform their ambitious concepts into reality. The key features of the EK-RA2A2 board are categorized into three groups viz. MCU native pin access, system control access, and ecosystem access. Typical applications include industrial and building automation, home appliances, medical and healthcare, consumer electronics, and system control for energy management.

Features

MCU native pin access:
- R7FA2A2AD3CFP MCU (referred to as RA MCU)
- 48MHz, Arm^® Cortex^®-M23 core
- 512KB Code Flash, 48KB SRAM
- 100 pins, LQFP package
- Native pin access through 3×20-pin and 1×40-pin male headers
- MCU current measurement points for precision current consumption measurement
- Multiple clock sources – RA MCU oscillator and sub-clock oscillator crystals, providing precision
- 32.768kHz reference clock
- Additional low-precision clocks (48MHz, 8MHz, and 32.768kHz) are available internal to the RA MCU

System control and ecosystem access:

  - External power supply (using surface mount clamp test points and power input vias)
- Three debug modes:
  - Debug on-board (SWD)
  - Debug in (SWD)
  - Debug out (JTAG and SWD)
- User LEDs and buttons:
  - Three user LEDs (red, blue, and green)
  - Power LED (white) indicating the availability of regulated power
  - Debug LED (yellow) indicating the debug connection
  - Two User buttons
  - One Reset button
- Five most popular ecosystems expansions:
  - 2 Seeed Grove system (I²C/Analog) connectors
  - SparkFun Qwiic^® connector
  - 2 Digilent Pmod™ (SPI and I²C) connectors
  - Arduino™ (Uno R3) connector
  - MikroElektronika mikroBUS™ connector
- MCU boot configuration jumper
