Product details
Overview
R5F10EBAGNA#20 from Renesas Electronics is a 32-pin, 32 MHz RL78/G1A 16-bit microcontroller with 32 KB flash, 4 KB data flash, 2 KB RAM, 18-channel 12-bit ADC, and ultra-low-power operation (66 µA/MHz active, 0.57 µA RTC+LVD). It integrates UART, I²C, SPI, LIN, RTC, PWM, and on-chip debug for embedded control in industrial sensors and battery-powered HMI.
For engineers reviewing the R5F10EBAGNA#20 datasheet, R5F10EBAGNA#20 pinout, R5F10EBAGNA#20 application, or R5F10EBAGNA#20 equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options aligned to industrial-temperature (−40°C to +105°C) operation and HWQFN-32 packaging.
Technical Context
The R5F10EBAGNA#20 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 cycles. It supports dual-clock domains: high-speed on-chip oscillator (32 MHz ±1% over voltage/temperature) and subsystem clock (32.768 kHz crystal or low-speed oscillator).
Its peripheral set includes two serial array units (supporting UART, simplified SPI/CSI, and I²C), up to 8-channel timer array with PWM capability, 12-bit interval timer, 15 kHz watchdog with window function, and hardware CRC for flash integrity - all designed for IEC/UL 60730-compliant safety-critical applications.
