Product details
Overview
R7F102GBC3CFP#HA0 from Renesas is a 32-pin LQFP-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 V to 5.5 V. It delivers ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates capacitive touch sensing for up to 29 keys, and supports UART, I²C, SPI, RTC, and 16-bit timers - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GBC3CFP#HA0 datasheet, R7F102GBC3CFP#HA0 pinout, R7F102GBC3CFP#HA0 application, or R7F102GBC3CFP#HA0 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, -40°C to +85°C industrial temperature grade, 32 KB flash/4 KB RAM memory configuration, CTSU2La capacitive touch unit, and support for SNOOZE mode sequencer for autonomous low-power sensing.
Technical Context
The R7F102GBC3CFP#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and independent subsystem clock (32.768 kHz).
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat transfer modes, and SNOOZE Mode Sequencer (SMS) enabling up to 32 autonomous low-power operations without CPU wake-up - critical for intermittent sensing in energy-constrained systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GBE3CFP#HA0 | Same package and pinout; 64 KB code flash / 4 KB RAM / 2 KB data flash instead of 32 KB flash. | Required when firmware exceeds 32 KB or needs larger bootloader + application partitioning. | Select R7F102GBE3CFP#HA0 only if code size demands >32 KB flash; otherwise R7F102GBC3CFP#HA0 offers optimal cost/power balance. |
| RL78/G13 R5F100LEAFB#30 | Legacy RL78/G13 family; 32 KB flash, 4 KB RAM, but no CTSU2La, no SNOOZE sequencer, and higher 60 µA/MHz active current. | Suitable for non-touch, lower-integration designs where legacy toolchain compatibility is prioritized over ultra-low power. | R7F102GBC3CFP#HA0 provides superior touch capability and 40% lower active current - choose unless G13-specific IP or qualification is mandated. |
Compared with R7F102GBE3CFP#HA0, the R7F102GBC3CFP#HA0 trades flash capacity for lower unit cost and identical low-power performance; versus RL78/G13 R5F100LEAFB#30, it delivers integrated touch sensing, SNOOZE autonomy, and 37.5 µA/MHz efficiency - making it the preferred choice for modern touch-enabled industrial edge nodes.
