Product details
Overview
R5F100LEGFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC/LVD. It operates from 1.6–5.5 V, achieves 41 DMIPS at 32 MHz, and delivers ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100LEGFA#30 datasheet, R5F100LEGFA#30 pinout, R5F100LEGFA#30 application, or R5F100LEGFA#30 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C industrial temperature rating (G-grade), on-chip debug support, self-programming flash with boot swap, and dual SPI/I²C/UART interfaces for sensor hub and HMI control designs.
Technical Context
The R5F100LEGFA#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - all accessible under single-supply 1.6–5.5 V operation.
Peripheral integration includes 16-channel 16-bit timers, 12-bit interval timer, calendar-based RTC with alarm/correction, 10-bit 26-channel ADC with internal 1.45 V reference and temperature sensor, and up to 10 I²C/Simplified I²C channels - configured via dedicated SFRs and supported by DMA (4-channel) for efficient data movement without CPU load.
