Product details
Overview
R7F100GPK3CFA#AA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V and supporting -40 to +105°C ambient temperature. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (6 channels), IICA (10 channels), and CSI (8 channels) for embedded control in power-constrained industrial systems.
For engineers reviewing the R7F100GPK3CFA#AA0 datasheet, R7F100GPK3CFA#AA0 pinout, R7F100GPK3CFA#AA0 application, or R7F100GPK3CFA#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, SNOOZE mode sequencer for ultra-low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
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 on-chip oscillator ±1.0%) or 30.5 µs at 32.768 kHz (subsystem clock). It supports multiply/divide/MAC instructions and 1 MB address space.
Power management includes HALT, STOP, and SNOOZE modes, with 41 µA/MHz active current and 210 nA data retention for 4 KB RAM. The SNOOZE mode sequencer executes up to 32 preconfigured commands (from 21 types) autonomously, enabling periodic sensor sampling or timer-triggered actions while keeping CPU, flash, and RAM powered down.

Does the R7F100GPK3CFA#AA0 support hardware-based capacitive touch sensing?
Yes, the R7F100GPK3CFA#AA0 integrates the CTSU2L capacitive sensing unit, supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) with built-in noise cancellation. It operates across the full 1.8–5.5 V supply range and requires no external components beyond standard PCB layout practices.
How many serial communication interfaces does the R7F100GPK3CFA#AA0 provide?
The R7F100GPK3CFA#AA0 provides up to 6 UARTA channels (with LIN support), 10 IICA channels (I²C-compatible), and 8 CSI channels (SPI-compatible). These are implemented in the Serial Array Unit (SAU) and Serial Interface (CSI/IICA/UARTA) modules, each with independent clock sources, FIFO buffers, and DMA trigger capability.
What low-power modes are available on the R7F100GPK3CFA#AA0, and what are their typical current draws?
The R7F100GPK3CFA#AA0 offers HALT, STOP, and SNOOZE modes. STOP mode draws ~0.23 µA (typ.) with RTC running; SNOOZE mode sequencer consumes ~1.2 µA while autonomously polling sensors; active current is 41 µA/MHz. Data retention for 4 KB RAM requires only 210 nA at 25°C.
Is the R7F100GPK3CFA#AA0 pin-compatible with other RL78/G23 100-pin variants?
Yes, all RL78/G23 100-pin variants-including R7F100GPK3CFA#AA0, R7F100GPL3CFA#AA0, and R7F100GPN3CFA#AA0-share identical pinout, package dimensions (14 × 14 mm LFQFP), and electrical characteristics.
