Product details
Overview
R7F100GPL3CFA#AA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich peripheral set including 16-bit timers, RTC, 12-bit ADC (26 channels), dual DAC, and multiple UART/I²C/SPI interfaces - deployed in smart metering and industrial HMI control systems.
For engineers reviewing the R7F100GPL3CFA#AA0 datasheet, R7F100GPL3CFA#AA0 pinout, R7F100GPL3CFA#AA0 application, or R7F100GPL3CFA#AA0 equivalent, key selection considerations include its LQFP-100 package with 0.65-mm pitch, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for ultra-low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode). It supports multiply/divide/MAC instructions and 1 MB address space, enabling deterministic real-time control in resource-constrained environments.
Peripherals are tightly coupled via the Event Link Controller (ELCL), allowing direct signal routing between timers, ADC, comparators, and communication interfaces without software intervention. The SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling → comparison → conditional wakeup) autonomously while CPU, flash, and RAM remain powered down.
