Detailed Description for R7FA2E1A93CNH#AA0
Product Overview
The R7FA2E1A93CNH#AA0 is a 32-bit microcontroller from Renesas Electronics Corporation, based on the ARM Cortex-M23 core and operating at 48MHz. It is part of the RA2E1 series and contains 128KB (128K x 8) of FLASH program memory, 16K x 8 of RAM, and 4K x 8 of EEPROM in a 32-HWQFN (5x5) surface-mount package. The device supports a supply voltage range of 1.6V to 5.5V and an operating temperature range of -40°C to 105°C (TA). It includes 23 I/O pins, external or internal oscillator options, and integrated analog-to-digital conversion using 10 channels of 12-bit SAR A/D.
Key Features
- 32-bit ARM Cortex-M23 core with a 48MHz operating speed.
- 128KB (128K x 8) FLASH program memory, 16K x 8 RAM, and 4K x 8 EEPROM.
- 23 I/O pins in a 32-HWQFN (5x5) surface-mount package.
- Communication interfaces include I2C, SmartCard, SPI, and UART/USART.
- Integrated peripherals include AES, capacitive touch, DMA, LVD, POR, PWM, temperature sensor, TRNG, and WDT.
- Analog input capability through 10-channel, 12-bit SAR A/D conversion.
Applications
- Embedded control systems requiring a 32-bit processor core and FLASH program memory.
- Sensor data acquisition using the 10-channel, 12-bit SAR A/D and temperature sensor.
- Secure communication endpoints using I2C, SmartCard, SPI, or UART/USART with AES and TRNG support.
- User-interface modules incorporating capacitive touch sensing.
- Pulse-width modulated digital control or timing functions using the integrated PWM and DMA peripherals.
- SmartCard interface modules using the SmartCard connectivity.
Design & Procurement Notes
Design considerations should align the 32-HWQFN (5x5) surface-mount package and exposed pad with the board layout and assembly process. The 1.6V to 5.5V supply range and -40°C to 105°C (TA) operating temperature range should be checked against system power and ambient conditions. The 23 I/O pins, 128KB FLASH, 16K x 8 RAM, and 4K x 8 EEPROM define the memory and pin budget for firmware and board connections. The I2C, SmartCard, SPI, and UART/USART interfaces, along with AES, TRNG, capacitive touch, DMA, LVD, POR, PWM, temperature sensor, and WDT peripherals, should be mapped to required system functions. External and internal oscillator options allow clocking to be selected according to board layout and timing needs. When specifying the device, use the exact manufacturer part number R7FA2E1A93CNH#AA0.
