Detailed Description for R7FA2E2A32DBY#HC1
Product Overview
The R7FA2E2A32DBY#HC1 from Renesas Electronics Corporation is a 32-bit microcontroller using an ARM Cortex-M23 core at 48MHz. It provides 16KB (16K x 8) FLASH, 8K x 8 RAM, and 2K x 8 EEPROM, with 11 I/O and four 12-bit SAR ADC channels. The device operates from 1.6V to 5.5V, uses an internal oscillator, and is rated for -40°C to 85°C (TA). Supported interfaces include I2C, I3C, SCI, SmartCard, SPI, and UART/USART. On-chip peripherals include AES, DMA, LVD, POR, PWM, a temperature sensor, TRNG, and WDT. The part uses a 16-WLCSP (1.84x1.87) surface-mount package, also identified as 16-UFBGA, WLCSP.
Key Features
- 32-bit ARM Cortex-M23 core operating at 48MHz.
- 16KB (16K x 8) FLASH program memory, 8K x 8 RAM, and 2K x 8 EEPROM.
- 11 I/O pins and four 12-bit SAR analog-to-digital converters.
- I2C, I3C, SCI, SmartCard, SPI, and UART/USART communication interfaces.
- AES, TRNG, DMA, PWM, temperature sensor, WDT, LVD, and POR peripherals.
- 1.6V to 5.5V supply range with an internal oscillator.
- Operating temperature range of -40°C to 85°C (TA).
- 16-WLCSP (1.84x1.87) surface-mount package, 16-UFBGA, WLCSP.
Applications
- Compact embedded control systems needing a 32-bit core, 11 I/O, and a small WLCSP footprint.
- Sensor acquisition nodes using four 12-bit SAR ADC channels and the internal temperature sensor.
- Secure local communication endpoints using AES, TRNG, and I2C, I3C, SPI, UART/USART, or SmartCard interfaces.
- Subsystems powered from 1.6V to 5.5V that require analog measurement and digital control.
- Motor, actuator, or power-control tasks using PWM outputs and DMA transfers.
Design & Procurement Notes
Design teams should map the 11 I/O count and selected communication interfaces to the PCB architecture before assigning peripherals, because the 16-WLCSP (1.84x1.87) package is compact but provides a limited pin count. The 1.6V to 5.5V supply range supports low-voltage rails and broader supply domains, but decoupling and power sequencing should be verified against the final layout. The internal oscillator provides a clock source for designs operating at 48MHz, while the -40°C to 85°C (TA) range should be considered with the enclosure and PCB thermal environment. For procurement, specify the exact part number R7FA2E2A32DBY#HC1 and the 16-UFBGA, WLCSP package to match the intended memory, peripheral, and interface configuration.
