Product details
Overview
R5F100LDGFA#50 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 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, and real-time clock - deployed in battery-powered industrial sensors and motor control edge nodes.
For engineers reviewing the R5F100LDGFA#50 datasheet, R5F100LDGFA#50 pinout, R5F100LDGFA#50 application, or R5F100LDGFA#50 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, integrated data flash with 1M rewrite cycles, background operation during program execution, and support for SNOOZE mode wake-up via peripheral interrupts.
Technical Context
The R5F100LDGFA#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-clock domains: high-speed main system clock (up to 32 MHz) and independent low-speed subsystem clock for RTC and LVD.
Its memory subsystem includes 128 KB on-chip code flash (1 KB block size, security-locked erase/write), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling firmware updates and data logging without halting application code. The DMA controller supports 4 channels with 2-cycle transfers between SFR and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LDGFA#50 | No data flash (0 KB); same core, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware update capability | Select when BGO logging or secure firmware updates are unnecessary and cost reduction is primary |
