Product details
Overview
R5F100LDGFA#30 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, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, RTC with calendar, and operates from 1.6–5.5 V across –40°C to +105°C for industrial control and sensor node applications.
For engineers reviewing the R5F100LDGFA#30 datasheet, R5F100LDGFA#30 pinout, R5F100LDGFA#30 application, or R5F100LDGFA#30 equivalent, key selection considerations include its industrial-grade temperature range (–40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation during program execution, 64-pin LQFP package with 26 analog input channels, and support for SNOOZE/HALT/STOP low-power modes in battery-constrained embedded systems.
Technical Context
The R5F100LDGFA#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports dual-clock domains: high-speed main system clock (up to 32 MHz) and independent subsystem clock (e.g., 32.768 kHz for RTC).
Its peripheral set includes 16× 16-bit timers, one 12-bit interval timer, one real-time clock with calendar/alarm/correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and up to 10 I²C/Simplified I²C channels - all accessible via dedicated SFRs and DMA-controlled transfers with 2-cycle latency between SFR and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LDGFB#30 | LQFP-64, 0.5 mm pitch (LFQFP), same memory/config but different package footprint | Requires PCB redesign due to tighter pitch and smaller body (10 × 10 mm vs. 12 × 12 mm) | Select when space-constrained layouts demand smaller footprint and assembly process supports 0.5 mm pitch |
| R5F101LDGFA#30 | Same package and pinout, but lacks data flash (0 KB); otherwise identical peripherals and performance | Not suitable for applications requiring nonvolatile parameter storage or field firmware updates | Choose only if data flash is unnecessary and cost reduction is prioritized over field upgrade capability |
Compared with R5F100LDGFA#30, R5F100LDGFB#30 offers identical functionality in a denser package requiring finer layout tolerances, while R5F101LDGFA#30 removes data flash entirely - eliminating BGO, secure rewrite, and parameter retention features critical for certified metering or OTA-updatable devices.
