Product details
Overview
R5F100LGDFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and low-power modes down to 0.57 μA. It operates from 1.6–5.5 V across –40°C to +105°C and targets industrial control panels requiring deterministic real-time response and long battery life.
For engineers reviewing the R5F100LGDFB#30 datasheet, R5F100LGDFB#30 pinout, R5F100LGDFB#30 application, or R5F100LGDFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, industrial-grade temperature range (–40°C to +105°C), on-chip data flash rewrite capability (1M cycles), RTC calendar function, and support for SNOOZE mode wake-up via serial interface events.
Technical Context
The R5F100LGDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator and supports background operation during data flash rewriting (BGO).
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, one real-time clock with calendar/alarm/correction, and three serial interfaces (CSI, UART/LIN, I²C) configurable across multiple channels - all operating under unified low-power HALT/STOP/SNOOZE modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
