Product details
Overview
R5F100CAGLA#U0 from Renesas is a 36-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 32 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 10-bit ADC (26 channels), real-time clock, UART/I²C/CSI interfaces, and 16-bit timers - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100CAGLA#U0 datasheet, R5F100CAGLA#U0 pinout, R5F100CAGLA#U0 application, or R5F100CAGLA#U0 equivalent, key selection criteria include its 36-pin WFLGA-0.5 mm pitch package, -40°C to +105°C industrial temperature grade (G suffix), integrated data flash with 1M rewrite cycles, and RL78 CPU core's 3-stage pipeline with configurable instruction timing (0.03125–30.5 μs).
Technical Context
The R5F100CAGLA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It features dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz), enabling dynamic power/performance scaling across HALT, STOP, and SNOOZE modes.
Its peripheral set includes 16-bit timer array (12 channels), 12-bit interval timer, calendar RTC with alarm/correction, and background operation-capable data flash (BGO). The MCU supports simultaneous execution from code flash while rewriting data flash, with dedicated RAM areas (e.g., F7F00H for xL-series) reserved for flash library operations.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100CCGLA#U0 | Same 36-pin WFLGA package, identical memory (32 KB flash / 4 KB data flash / 2 KB RAM), but rated for -40°C to +85°C (C-grade) | Suitable for consumer-grade appliances where extended temperature range is not required | Select when cost optimization is prioritized over industrial ambient qualification |
| R5F101CAGLA#U0 | Pin-compatible 36-pin WFLGA variant without data flash (0 KB); otherwise identical core, peripherals, and temperature grade (-40°C to +105°C) | Applicable where firmware storage suffices and runtime parameter logging is handled externally | Choose when data flash functionality is unnecessary and BOM cost reduction is critical |
