Product details
Overview
R7F102GCC2DLA#HC0 from Renesas is a 36-pin WFLGA-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 to 5.5 V. It delivers ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, RTC, capacitive touch sensing (up to 29 keys), and supports UART, I²C, and SPI interfaces for battery-powered HMI and industrial control applications.
For engineers reviewing the R7F102GCC2DLA#HC0 datasheet, R7F102GCC2DLA#HC0 pinout, R7F102GCC2DLA#HC0 application, or R7F102GCC2DLA#HC0 equivalent, this page provides verified package mapping (WFLGA-36, 4 × 4 mm, 0.50-mm pitch), confirmed 36-pin multiplexed I/O functions, real-world low-power timing and sensing use cases, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R7F102GCC2DLA#HC0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 a SNOOZE mode sequencer enabling 32-step low-power background processing without CPU, RAM, or flash activation.
Peripheral integration includes a 21-instruction SNOOZE sequencer, Event Link Controller (ELC) routing 20 event signals between peripherals, and a Capacitive Touch Sensing Unit (CTSU2La) supporting self- and mutual-capacitance configurations across up to 29 pins - all operating within the 1.6–5.5 V supply range and -40 to +85°C ambient temperature.

It includes hardware noise cancellation and operates across the full 1.6–5.5 V supply range, making it suitable for consumer and industrial touch interfaces.
What is the memory configuration of the R7F102GCC2DLA#HC0?
The R7F102GCC2DLA#HC0 contains 32 KB of code flash memory (organized in 2 KB blocks), 2 KB of data flash memory rated for 1,000,000 write/erase cycles, and 4 KB of on-chip RAM. Data flash supports background operation, allowing program execution from code flash during rewrites - essential for reliable parameter storage and firmware updates.
What package type and pin count does the R7F102GCC2DLA#HC0 use?
The R7F102GCC2DLA#HC0 uses a 36-pin WFLGA (Wafer-Level Chip-Scale Package) with 4 × 4 mm body size and 0.50-mm pitch. This package is optimized for space-constrained designs and requires connection of the exposed die pad to VSS for thermal and EMI performance, as specified in Renesas' layout guidelines.
How does the SNOOZE mode sequencer function in the R7F102GCC2DLA#HC0?
The SNOOZE mode sequencer in the R7F102GCC2DLA#HC0 executes up to 32 predefined commands (e.g., ADC conversion, CTSU scan, register comparison) autonomously without CPU, RAM, or flash activation. It operates using only the low-power subsystem clock, enabling ultra-low-power periodic sensing - reducing average current to sub-microamp levels in battery applications.
Is the R7F102GCC2DLA#HC0 pin-compatible with other RL78/G22 variants?
The R7F102GCC2DLA#HC0 is pin-compatible with other 36-pin WFLGA variants in the RL78/G22 family, including R7F102GCE2DLA#HC0 (64 KB flash) and R7F102GCC3CLA#AC0 (105°C rating).
