Product details
Overview
R7F100GLN3CFA#HA0 from Renesas is a 64-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and supports real-time clock, multiple UART/I²C/SPI interfaces, and SNOOZE mode sequencer for battery-powered HMI and sensor node applications.
For engineers reviewing the R7F100GLN3CFA#HA0 datasheet, R7F100GLN3CFA#HA0 pinout, R7F100GLN3CFA#HA0 application, or R7F100GLN3CFA#HA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, 512 KB flash/48 KB RAM configuration, and support for CTSU2L capacitive sensing and background data flash rewriting.
Technical Context
The R7F100GLN3CFA#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 low-power processes using 21 command types without CPU involvement, enabling autonomous sensor polling and wake-up control.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain options. The device features a 12-bit A/D converter with 26 input channels, internal 1.48 V reference, and temperature sensor.
