Product details
Overview
R7F100GGL3CFB#BA0 from Renesas is a 48-pin LFQFP, industrial-grade RL78/G23 16-bit microcontroller with 384 KB code flash, 8 KB data flash, 32 KB RAM, 1.6–5.5 V operation, and integrated capacitive touch sensing unit (CTSU2L). It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention) and supports real-time clock, multiple UART/I²C/SPI interfaces, and SNOOZE mode for battery-powered sensor nodes and smart home controllers.
For engineers reviewing the R7F100GGL3CFB#BA0 datasheet, R7F100GGL3CFB#BA0 pinout, R7F100GGL3CFB#BA0 application, or R7F100GGL3CFB#BA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, 384 KB flash/32 KB RAM configuration, -40 to +105°C industrial temperature rating, and CTSU2L-based touch interface capability for space-constrained embedded control designs.
Technical Context
The R7F100GGL3CFB#BA0 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 integrates a SNOOZE mode sequencer (SMS) enabling up to 32 low-power background processes without CPU wake-up.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfer, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain and controlled-current drive options - all optimized for mixed-signal industrial sensing and actuation.
