Product details
Overview
R7F100GLH3CFA#AA0 from Renesas is an RL78/G23 64-pin industrial-grade 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V; features ultra-low-power operation (41 µA/MHz), 32.768-kHz RTC, 16-bit TAU timers, and capacitive touch sensing for embedded control in battery-powered and space-constrained applications.
For engineers reviewing the R7F100GLH3CFA#AA0 datasheet, R7F100GLH3CFA#AA0 pinout, R7F100GLH3CFA#AA0 application, or R7F100GLH3CFA#AA0 equivalent, key selection criteria include industrial temperature range (−40 to +105°C), LQFP-64 0.65-mm pitch package compatibility, integrated CTSU2L capacitive sensing unit, and support for SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F100GLH3CFA#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz); it integrates a SNOOZE mode sequencer (SMS) enabling up to 32 autonomous operations without CPU wake-up, and an Event Link Controller (ELCL) for hardware-triggered peripheral coordination.
It includes a 12-bit A/D converter with up to 26 channels, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and a real-time clock with alarm and correction functions - all operating within the same 1.6–5.5 V supply range and −40 to +105°C ambient specification.
