Product details
Overview
R7F100GPJ3CFB#AA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for real-time control in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GPJ3CFB#AA0 datasheet, R7F100GPJ3CFB#AA0 pinout, R7F100GPJ3CFB#AA0 application, or R7F100GPJ3CFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, 256 KB flash/24 KB RAM memory configuration, CTSU2L-based touch interface capability, and SNOOZE mode sequencer for ultra-low-power periodic wake-up without CPU involvement.
Technical Context
The R7F100GPJ3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer executing up to 32 preconfigured commands (e.g., ADC sampling, comparator comparison, GPIO toggle) without waking the CPU or accessing flash/RAM.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (26 channels), 8-bit DAC (2 channels), 2 comparators, UARTA/LIN (3 channels), IICA (up to 10 channels), CSI (up to 8 channels), and ELCL for event-driven peripheral linking - all operating within 1.6–5.5 V supply range and qualified for industrial temperature.
