Detailed Description for R7FA4M3AF2CBQ#BC0
Product Overview
The R7FA4M3AF2CBQ#BC0 from Renesas Electronics Corporation is a 32-bit ARM Cortex-M33 microcontroller in the RA4M3 series. It operates at 100 MHz and provides 1 MB (1M x 8) of FLASH program memory, 128K x 8 RAM, and 8K x 8 EEPROM. The device supports a 2.7 V to 3.6 V supply range, offers 45 I/O pins, and is housed in a surface-mount 64-LFBGA (6x6) package.
Key Features
- 32-bit ARM Cortex-M33 core with 100 MHz operating speed.
- 1 MB (1M x 8) FLASH program memory, 128K x 8 RAM, and 8K x 8 EEPROM.
- 45 I/O pins and a 2.7 V to 3.6 V supply range.
- Connectivity includes CANbus, I2C, QSPI, SCI, SPI, UART/USART, and USB.
- Peripherals include capacitive touch, AES crypto, RSA, SHA, DMA, LVD, POR, PWM, temperature sensor, and WDT.
- Data converters include 11 x 12-bit SAR ADC and 2 x 12-bit DAC.
- Internal oscillator and surface-mount 64-LFBGA (6x6) package.
- Operating temperature range of -40°C to 85°C (TA).
Applications
- Embedded control subsystems that use 45 I/O pins, PWM, and serial communication interfaces.
- User-interface modules that combine capacitive touch sensing with USB, SPI, or UART links.
- Data-acquisition nodes that use 12-bit ADC and DAC resources with CANbus or other serial interfaces.
- Secure embedded devices that use AES, RSA, and SHA peripherals for cryptographic processing.
Design & Procurement Notes
For design planning, match the board power architecture to the 2.7 V to 3.6 V supply range and verify that the operating environment remains within the -40°C to 85°C (TA) range. The 1 MB FLASH, 128K x 8 RAM, and 8K x 8 EEPROM sizes should be evaluated against firmware, runtime data, and configuration storage needs. Map the 45 I/O pins and interfaces, including CANbus, I2C, QSPI, SCI, SPI, UART/USART, and USB, to the required subsystem connections. Because the device is a surface-mount 64-LFBGA (6x6) package, PCB land pattern, routing, and inspection planning should account for the package footprint. The internal oscillator should be considered when planning the clock architecture, and analog requirements should be checked against the 11 x 12-bit SAR ADC and 2 x 12-bit DAC resources.
