Detailed Description for R7FA2A1AB3CFM#AA0
Product Overview
The R7FA2A1AB3CFM#AA0 microcontroller from Renesas Electronics Corporation is a 32-bit embedded processor built around an ARM Cortex-M23 core and operating at 48MHz. It includes 256KB (256K x 8) of FLASH program memory, 32K x 8 RAM, and 8K x 8 EEPROM in a 64-LFQFP (10x10) surface-mount package. The device supports a 1.6V to 5.5V supply range and an operating temperature range of -40°C to 105°C (TA).
Key Features
- ARM Cortex-M23 32-bit core operating at 48MHz
- 256KB (256K x 8) FLASH program memory with 32K x 8 RAM and 8K x 8 EEPROM
- 46 general I/O pins and 64-LFQFP (10x10) surface-mount package
- Internal oscillator and supply range of 1.6V to 5.5V
- Peripherals include capacitive touch, DMA, LVD, POR, PWM, and WDT
- Connectivity options include CANbus, EBI/EMI, I2C, SCI, SPI, UART/USART, and USB
- Analog resources include A/D 17x16b, 8x24b SAR, Sigma-Delta and D/A 2x8b, 1x12b
- Operating temperature range is -40°C to 105°C (TA)
Applications
- Embedded control boards requiring mixed digital I/O, serial interfaces, and local FLASH program storage
- Sensor measurement systems using ADC inputs and DAC outputs for analog signal processing
- User interface modules with capacitive touch sensing and PWM-driven indicators
- Communications nodes that combine UART/SCI, SPI, I2C, USB, or CANbus links
- Embedded devices operating from a 1.6V to 5.5V supply and requiring 32K x 8 RAM
Design & Procurement Notes
Design teams should confirm that the 256KB FLASH, 32K x 8 RAM, and 8K x 8 EEPROM are sufficient for firmware code, data buffers, and nonvolatile parameter storage. The 46 I/O count and 64-LFQFP (10x10) package should be checked against board layout, pin assignment, and thermal constraints. The 1.6V to 5.5V supply range and -40°C to 105°C (TA) operating range support a range of embedded environments, but system-level power, timing, and analog accuracy requirements still need evaluation. The internal oscillator may reduce external clock components, while designs with strict timing margins should verify the oscillator against their requirements. The available connectivity, peripherals, and converter resources define the device's functional scope and should be matched to the target architecture.
