Product details
Overview
R5F100LCDFA#X0 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and targets low-power industrial control applications including sensor nodes and motor drive interfaces.
For engineers reviewing the R5F100LCDFA#X0 datasheet, R5F100LCDFA#X0 pinout, R5F100LCDFA#X0 application, or R5F100LCDFA#X0 equivalent, key selection criteria include its 64-pin LQFP package, industrial-grade -40°C to +85°C temperature rating (D-grade), integrated RTC with alarm/calendar, 26-channel 10-bit ADC, and dual UART/LIN support for embedded communication subsystems.
Technical Context
The R5F100LCDFA#X0 implements the RL78 CISC core with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a dedicated RTC with calendar, alarm, and clock correction functions - all operable in ultra-low-power STOP mode (0.57 μA).
Its peripheral set includes 3 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels supporting background data flash rewriting during program execution - enabling robust firmware updates without halting real-time operation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGDFA#X0 | Same 64-pin LQFP package, identical 128 KB flash/8 KB data flash/12 KB RAM, but rated for A-grade (-40°C to +85°C consumer temp range) | Lacks D-grade qualification; unsuitable for industrial environments requiring extended temperature validation | Select only for cost-sensitive commercial applications where industrial temp certification is not required |
| R5F101LCDFA#X0 | Pin-compatible 64-pin LQFP variant with no data flash memory (0 KB), same 128 KB code flash and 12 KB RAM | Cannot perform in-field data logging or parameter storage; requires external EEPROM/NV for configuration retention | Choose when data flash functionality is unnecessary and BOM cost reduction is prioritized over non-volatile data storage |
