Product details
Overview
R7F100GGG3CFB#AA0 from Renesas is an RL78/G23 48-pin LFQFP microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates a capacitive touch sensing unit (CTSU2L), 16-bit timer array (TAU), RTC, and multiple serial interfaces including UARTA, IICA, and SAU for embedded control in industrial sensor nodes and battery-powered HMI devices.
For engineers reviewing the R7F100GGG3CFB#AA0 datasheet, R7F100GGG3CFB#AA0 pinout, R7F100GGG3CFB#AA0 application, or R7F100GGG3CFB#AA0 equivalent, key selection considerations include its 48-pin LFQFP-0.5 mm package, -40 to +105°C industrial temperature grade (C-field), SNOOZE mode sequencer for autonomous low-power sensing, and CTSU2L support for up to 64-key mutual-capacitance touch panels.
Technical Context
The R7F100GGG3CFB#AA0 implements the RL78 CPU core with a 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). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation, enabling deterministic sub-microamp wake-up-triggered operation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware event routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Remote Control Signal Receiver (REMC) with four configurable waveform pattern matchers for IR remote decoding. All operate under the same 1.6–5.5 V supply and industrial temperature range.
