Product details
Overview
R7F102GEC2DNP#HA0 from Renesas is a 40-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6–5.5 V. It delivers true low-power performance (37.5 µA/MHz active, 200 nA STOP mode), integrates up to 29 capacitive touch sensors, and supports UART, I²C, SPI, RTC, and 16-bit timers for embedded control in consumer-grade applications (−40 to +85°C).
For engineers reviewing the R7F102GEC2DNP#HA0 datasheet, R7F102GEC2DNP#HA0 pinout, R7F102GEC2DNP#HA0 application, or R7F102GEC2DNP#HA0 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch) package, 64 KB flash/4 KB RAM memory configuration, CTSU2La capacitive touch support, SNOOZE mode sequencer for ultra-low-power sensor polling, and dual-voltage I/O compatibility (1.8/2.5/3.0 V interface capability).
Technical Context
The R7F102GEC2DNP#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It features a dedicated SNOOZE mode sequencer (SMS) supporting 32 sequential operations using 21 command types-enabling autonomous, CPU-free capacitive sensing and timer-based wake-up without RAM/flash activation.
Its peripheral set includes a 10-bit A/D converter with 10 analog inputs and internal 1.48 V reference, dual I²C interfaces (IICA/IICA0), up to 4 UARTA channels (one with LIN support), and an Event Link Controller (ELC) that enables direct hardware-triggered peripheral chaining-reducing CPU overhead for real-time signal conditioning and communication handshaking.
