Product details
Overview
R7F102G7C3CNP#HA0 from Renesas is a 24-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash. It operates from 1.6 V to 5.5 V, achieves 37.5 µA/MHz active current and 200 nA STOP-mode current, and integrates capacitive touch sensing for up to 29 keys - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102G7C3CNP#HA0 datasheet, R7F102G7C3CNP#HA0 pinout, R7F102G7C3CNP#HA0 application, or R7F102G7C3CNP#HA0 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) footprint, -40°C to +85°C temperature grade, 32 KB flash capacity, integrated CTSU2La capacitive sensing unit, and support for UARTA, IICA, and SAU peripherals.
Technical Context
The R7F102G7C3CNP#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Its power management includes HALT, STOP, and SNOOZE modes - the latter driven by a dedicated sequencer that executes up to 32 low-power processes without CPU, flash, or RAM involvement. Peripheral integration includes a 10-bit A/D converter (10-channel), RTC with alarm and correction, and event link controller (ELC) for autonomous peripheral coordination.
