Product details
Overview
R5F101PHDFA#V0 from Renesas is a 100-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), 12-bit RTC, 10-bit ADC (26 channels), and integrated UART/LIN, I²C, and CSI interfaces - deployed in smart metering, industrial sensors, and battery-powered HMI control units.
For engineers reviewing the R5F101PHDFA#V0 datasheet, R5F101PHDFA#V0 pinout, R5F101PHDFA#V0 application, or R5F101PHDFA#V0 equivalent, key selection criteria include its 100-pin LQFP package with 26 analog input channels, 12-bit real-time clock with calendar/alarm, LIN-bus support in UART mode, and data flash endurance of 1,000,000 rewrites - critical for firmware-over-the-air (FOTA) and parameter logging in field-deployed devices.
Technical Context
The R5F101PHDFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and background operation (BGO) for data flash rewriting while executing code from program memory.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI channels - all configurable via register-based control without external glue logic. The on-chip voltage detector (LVD) offers 14 selectable reset/interrupt thresholds, and DMA supports 2–4 channels with 2-clock transfers between SFR and internal RAM.
