Product details
Overview
R7F100GFN3CFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, 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 (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in industrial human-machine interface modules requiring robust low-power operation.
For engineers reviewing the R7F100GFN3CFP#HA0 datasheet, R7F100GFN3CFP#HA0 pinout, R7F100GFN3CFP#HA0 application, or R7F100GFN3CFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +105°C industrial temperature grade (3C), 256 KB flash/24 KB RAM memory configuration, SNOOZE mode sequencer for autonomous peripheral control, and CTSU2L support for up to 64-key mutual-capacitance touch panels.
Technical Context
The R7F100GFN3CFP#HA0 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). Its power management includes HALT, STOP, and SNOOZE modes, with STOP wakeup in under 4 µs and SNOOZE sequencer enabling 32-step autonomous processing without CPU involvement.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS), Logic & Event Link Controller (ELCL) for configurable event routing between peripherals, and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes with chain transfer capability - all optimized for deterministic real-time response in resource-constrained embedded systems.
