Product details
Overview
R7F100GEJ3CNP#AA0 from Renesas is a 40-pin HWQFN-packaged RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and supports industrial temperature range (−40 to +105°C) for embedded control in battery-powered industrial sensors.
For engineers reviewing the R7F100GEJ3CNP#AA0 datasheet, R7F100GEJ3CNP#AA0 pinout, R7F100GEJ3CNP#AA0 application, or R7F100GEJ3CNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, C-grade industrial qualification, 192 KB flash/20 KB RAM memory configuration, and integrated CTSU2L for touch HMI in space-constrained designs.
Technical Context
The R7F100GEJ3CNP#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer enables autonomous low-power periodic sensing without CPU wake-up, using 32 programmable commands across 21 operations.
Peripheral integration includes Logic & Event Link Controller (ELCL) for hardware-triggered signal routing, Data Transfer Controller (DTC) with chain transfer, and dual serial interface types: up to 10 I²C/Simplified I²C channels and 6 UARTA/LIN-capable channels - all configurable via peripheral I/O redirection register (PIOR).

Debugging includes full breakpoint, watchpoint, and memory access capabilities without requiring additional debug circuitry.
How many capacitive touch channels does the R7F100GEJ3CNP#AA0 support, and what configurations are available?
The R7F100GEJ3CNP#AA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix). It uses dedicated pins P20–P26, P30, P31, P50–P51, P60–P62, and P70–P73 - totaling 26 physical electrodes usable in either configuration, with automatic noise cancellation and auto-tuning.
What serial communication interfaces are available on the R7F100GEJ3CNP#AA0, and how many instances of each?
The R7F100GEJ3CNP#AA0 provides up to 10 I²C/Simplified I²C channels (IICA), 6 UARTA channels (with LIN bus support), and 8 CSI channels (SPI-like). Channel allocation depends on pin multiplexing: e.g., P10–P12 support SCK00/SI00/SO00 (CSI0); P14–P15 support SCK20/SI20 (CSI2); P60–P61 serve SCLA0/SDAA0 (IICA0).
Is the R7F100GEJ3CNP#AA0 qualified for industrial temperature operation, and what packaging supports that rating?
Yes, the R7F100GEJ3CNP#AA0 carries the 'C' suffix indicating industrial qualification (−40 to +105°C ambient). This rating applies specifically to the HWQFN-40 package (P/N suffix NP), as confirmed in Renesas documentation R01DS0395EJ0140.
