Overview
R7F100GLK2DFB#BA0 from Renesas is a 64-pin LFQFP, 512-KB code flash, 48-KB RAM RL78/G23 16-bit MCU with true low-power operation (41 µA/MHz), 210-nA data retention current, integrated capacitive touch sensing (CTSU2L), and industrial-grade −40 to +105°C operation. It integrates UARTA, IICA, SAU, RTC, 16-bit TAU timers, and hardware SNOOZE mode sequencer for battery-powered HMI and sensor control applications.
For engineers reviewing the R7F100GLK2DFB#BA0 datasheet, R7F100GLK2DFB#BA0 pinout, R7F100GLK2DFB#BA0 application, or R7F100GLK2DFB#BA0 equivalent, key selection criteria include its 512-KB flash/48-KB RAM configuration, LFQFP-64 (0.50-mm pitch) package, industrial temperature rating (−40 to +105°C), CTSU2L support for up to 64 keys, and SNOOZE mode sequencer enabling CPU-free periodic wake-up and sensor polling.
Technical Context
The R7F100GLK2DFB#BA0 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 power management includes HALT, STOP, and SNOOZE modes - the latter using a dedicated sequencer with 32 programmable steps and 21 command types to execute sensor reads, comparisons, and conditional wake-ups without CPU or memory activation.
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 a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under VDD = 1.8–5.5 V.

The R7F100GLK2DFB#BA0 guarantees 210 nA data retention current for 4 KB of RAM, as stated in the RL78/G23 datasheet (R01DS0395EJ0140) Section 1.1. This specification holds across the full industrial temperature range (−40 to +105°C) and at VDD = 1.6–5.5 V, enabling decade-long data retention on supercapacitor backup in energy meter and alarm system applications.
How many UARTA channels does the R7F100GLK2DFB#BA0 support, and are they fully independent?
The R7F100GLK2DFB#BA0 supports up to 6 independent UARTA channels, each with dedicated registers, baud rate generators, and interrupt vectors. This is confirmed in Section 1.1 of the R01DS0395EJ0140 datasheet and applies to the R7F100GLK2DFB#BA0 as a 64-pin, 512-KB flash variant. All 6 channels can operate simultaneously - for example, one for LIN bus, two for RS-485 Modbus, and three for debug/logging streams.
