Product details
Overview
R5F101PHAFB#30 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, ultra-low-power 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V and rated for -40°C to +85°C industrial use. It delivers 41 DMIPS at 32 MHz, integrates a real-time clock, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and supports HALT/STOP/SNOOZE low-power modes - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101PHAFB#30 datasheet, R5F101PHAFB#30 pinout, R5F101PHAFB#30 application, or R5F101PHAFB#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, absence of on-chip data flash, industrial temperature rating, and support for background data flash programming in compatible variants.
Technical Context
The R5F101PHAFB#30 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 subsystem clock). Its memory map spans 1 MB address space with 96 KB code flash and 8 KB RAM, and it includes dedicated peripherals such as a 12-bit interval timer, watchdog timer, and on-chip voltage detector with 14-level LVD interrupt/reset selection.
It features dual serial interface sets: up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels; plus 8–16 16-bit timers, a calendar-capable RTC with alarm and correction, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating within the same 1.6–5.5 V supply range.

FAQ
What is the flash memory configuration of the R5F101PHAFB#30?
The R5F101PHAFB#30 contains 96 KB of on-chip code flash memory and zero data flash memory. Unlike the R5F100x series, this variant omits data flash to reduce cost and test overhead. Code flash supports self-programming with boot swap and flash shield window functions, but persistent data storage requires external EEPROM or FRAM.
Does the R5F101PHAFB#30 support hardware debugging?
Yes, the R5F101PHAFB#30 supports on-chip debugging via the single-wire debug interface using pins P13 (TOOLnTRST) and P11/P12 (TOOLRxD/TOOLTxD). It is compatible with Renesas E2 emulator and CS+ IDE. No external debug header is required - debug signals share functional pins, minimizing PCB footprint.
What is the maximum ADC resolution and channel count supported by the R5F101PHAFB#30?
The R5F101PHAFB#30 integrates an 8/10-bit successive approximation A/D converter with up to 26 analog input channels. Resolution is selectable per channel; 10-bit mode is standard for precision sensing. The ADC includes internal 1.45 V reference and integrated temperature sensor - both usable without external components.
Can the R5F101PHAFB#30 operate from a 1.8 V supply?
Yes, the R5F101PHAFB#30 operates across 1.6 V to 5.5 V, fully supporting 1.8 V nominal supply. At 1.8 V, maximum operating frequency is reduced to 16 MHz (per datasheet voltage-frequency curve), delivering ~20.5 DMIPS. All I/Os remain functional, and the 1.45 V internal ADC reference remains stable.
Is the R5F101PHAFB#30 pin-compatible with other RL78/G13 100-pin variants?
Yes, the R5F101PHAFB#30 shares identical 100-pin LFQFP-0.5mm mechanical footprint and pin assignment with all RL78/G13 100-pin members (e.g., R5F101PJAFB#30, R5F100PHAFB#30). Signal mapping, power/ground pin locations, and debug interface pins are consistent - enabling drop-in replacement within the same package family.
