Product details
Overview
R5F101PHAFA#30 from Renesas is a 32-bit RL78/G13 microcontroller with 96 KB flash memory, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 10-bit A/D converter (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101PHAFA#30 datasheet, R5F101PHAFA#30 pinout, R5F101PHAFA#30 application, or R5F101PHAFA#30 equivalent, key selection criteria include its LQFP-64 (0.65 mm pitch) package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D suffix), and integrated low-voltage detection with 14-level programmable reset thresholds.
Technical Context
The R5F101PHAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16 × 16-bit timers, 3 × I²C/Simplified I²C channels, 2–4 UART/LIN channels, 2–8 CSI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable via register-based control without external timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PHAFA#30 | Includes 4 KB data flash; identical pinout and peripherals but higher BOM cost | Preferred where field firmware updates require dedicated nonvolatile parameter storage | Select when data flash endurance (1M cycles) and background rewrite are mandatory |

FAQ
What is the flash memory configuration of the R5F101PHAFA#30?
The R5F101PHAFA#30 contains 96 KB of on-chip code flash memory and no dedicated data flash memory (R5F101x series designation confirms data flash omission). It does include 8 KB of RAM for variables and stack. The flash supports block erase (1 KB), self-programming with boot swap, and flash shield window protection against unauthorized access - all accessible via the on-chip debug interface.
Does the R5F101PHAFA#30 support real-time clock functionality?
Yes, the R5F101PHAFA#30 integrates a full-featured real-time clock (RTC) with calendar support (up to 99 years), alarm interrupt, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, drawing only 0.57 μA total with LVD enabled - enabling long-term timekeeping in battery-backed applications without external RTC ICs.
What package type and pin count does the R5F101PHAFA#30 use?
The R5F101PHAFA#30 uses a 64-pin LQFP package with 0.65 mm pitch (12 × 12 mm body, PLQP0064JA-A code). It is lead-free and RoHS-compliant, with an exposed thermal pad for enhanced heat dissipation. Pin compatibility is maintained across all R5F101x LQFP-64 variants, including R5F101PHDFA#30 and R5F101PLAFA#30.
How does the low-power operation of the R5F101PHAFA#30 compare to similar MCUs?
The R5F101PHAFA#30 achieves 66 μA/MHz in active mode and 0.57 μA in STOP mode with RTC + LVD - outperforming most 32-bit MCUs in its class. This is enabled by RL78's optimized peripheral gating, multiple low-power modes (HALT, STOP, SNOOZE), and voltage-scalable logic. For example, it draws ~40% less current than comparable ARM Cortex-M0+ devices under identical RTC+sensor polling workloads.
Can the R5F101PHAFA#30 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F101PHAFA#30 supports different-potential interface: selected I/O ports (P00–P07, P10–P17, etc.) can be configured with TTL input buffers and on-chip pull-up resistors, allowing safe connection to 1.8 V, 2.5 V, or 3 V logic without level shifters. Input thresholds are referenced to VDD, and output drive strength is adjustable per port - verified across -40°C to +85°C operation.
