Product details
Overview
R5F100PHAFB#X0 from Renesas is a 100-pin LFQFP (14 × 14 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100PHAFB#X0 datasheet, R5F100PHAFB#X0 pinout, R5F100PHAFB#X0 application, or R5F100PHAFB#X0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade (G suffix), integrated 12-bit ADC (26 channels), real-time clock with calendar, and hardware multiplier/divider supporting deterministic motor control loops.
Technical Context
The R5F100PHAFB#X0 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). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI/SPI channels, DMA controller (4 channels), and background operation (BGO) for concurrent code execution during data flash rewriting - enabling seamless firmware updates without halting real-time tasks.

The R5F100PHAFB#X0 is rated for industrial operation from -40°C to +105°C, as indicated by the 'G' suffix in its part number. This rating is validated per Renesas' qualification standards and applies across the full 1.6 V to 5.5 V supply range, enabling deployment in harsh environments such as motor drive enclosures and outdoor utility meters.
Does the R5F100PHAFB#X0 include an integrated temperature sensor?
Yes, the R5F100PHAFB#X0 includes an on-chip temperature sensor usable via the ADC. Its typical accuracy is ±2°C over the -40°C to +105°C range, and it is explicitly supported in HS (high-speed main) mode per the datasheet. This sensor eliminates the need for external thermal monitoring in applications like thermal shutdown protection or ambient compensation.
How many analog input channels does the R5F100PHAFB#X0 support?
The R5F100PHAFB#X0 supports up to 26 analog input channels for its 12-bit A/D converter. These channels are mapped to specific pins (e.g., ANI0–ANI25) and can be configured with programmable sampling time and conversion clock sources - enabling simultaneous acquisition from multi-sensor arrays in HVAC and industrial monitoring systems.
What debug interface does the R5F100PHAFB#X0 use?
The R5F100PHAFB#X0 uses Renesas' on-chip debug interface accessible via the TOOLRxD/TOOLTxD pins (e.g., P11/P12), compatible with E2 emulator Lite and E2 studio IDE. It supports full break-and-trace functionality, flash programming, and real-time variable watch - all without requiring additional debug headers or SWD/JTAG adapters.
Is the R5F100PHAFB#X0 pin-compatible with other RL78/G13 100-pin variants?
Yes, the R5F100PHAFB#X0 shares identical pinout and footprint with all other RL78/G13 100-pin LFQFP variants (e.g., R5F100PLAFB#X0, R5F101PHAFB#X0), including matching power, ground, reset, and debug pin locations.
