Overview
R5F104PHAFB#10 from Renesas is a 100-pin LFQFP (0.5 mm pitch), 128 KB flash, 8 KB data flash, 16 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), targeting industrial motor control and sensor-based HMI systems.
For engineers reviewing the R5F104PHAFB#10 datasheet, R5F104PHAFB#10 pinout, R5F104PHAFB#10 application, or R5F104PHAFB#10 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, integrated 12-bit RTC with calendar/alarm, dual UART/LIN support, 12-channel 16-bit TAU timer, and 10-bit 19-channel ADC with internal temperature sensor and 1.45 V reference.
Technical Context
The R5F104PHAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention.
Its power management includes on-chip POR and 14-level LVD with selectable interrupt/reset behavior, while the Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes activated by 19–26 configurable event sources, including chain transfer for multi-step memory operations.
