It provides 40 I/O pins, a 10-channel 10-bit ADC, and rich peripherals including DMA, LVD, POR, PWM, and WDT, with support for UART, CSI, I²C, and LIN communication interfaces. Operating from 1.6V to 5.5V with a temperature range of -40℃ to +85℃, it is widely used in industrial control, consumer electronics, home appliances, sensors, and building automation.

R5F100FGAFP#10 Key Features

RL78 16-Bit CPU Core at 32MHz: Powered by an RL78 16-bit CISC CPU core with a 3-stage pipeline, running at up to 32MHz and delivering 43.2 DMIPS. The minimum instruction execution time can be flexibly switched from high-speed 0.03125 μs (@32MHz high-speed on-chip oscillator) to ultra-low-speed 30.5 μs (@32.768kHz subsystem clock).

Large Memory Configuration: 128KB code flash with 1KB block size, supporting block erase and rewrite prohibition (security function) and self-programming (with boot swap function/flash shield window function). 12KB RAM and 8KB data flash that supports Background Operation (BGO) , enabling independent data read/write while the CPU executes code, with 1,000,000 erase/write cycles.

Industry-Leading Ultra-Low Power: CPU operating current of only 66 μA/MHz and STOP mode standby current as low as 230 nA. Only 0.57 μA when operating with just RTC and LVD. Supports HALT mode, STOP mode, and SNOOZE mode. The 1.6V to 5.5V wide operating voltage range supports 5V systems and battery-powered devices.

Rich Peripherals & Communication Interfaces: 40 I/O pins, 10-channel 10-bit ADC, 2-channel DMA controller, LVD, POR, PWM, WDT, temperature sensor, and RTC. Integrated 3-channel SCI/UART, 4-channel SPI, 5-channel I²C, and 1-channel LIN interfaces.

LQFP-44 Compact Package: LQFP-44 (10×10×1.6mm) package with 0.8mm pitch, MSL rating 3 (168 hours) , RoHS compliant, Pb-free design.
