Product details
Overview
R5F101PFAFB#30 from Renesas is a 100-pin, LFQFP-0.5mm-pitch, 32-bit RL78/G13 microcontroller with no data flash memory, 64 KB code flash, 4 KB RAM, and industrial-grade operation (−40°C to +85°C). It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active current, and supports ultra-low-power STOP mode (0.57 μA) with RTC and LVD - ideal for battery-powered industrial sensors and motor control edge nodes.
For engineers reviewing the R5F101PFAFB#30 datasheet, R5F101PFAFB#30 pinout, R5F101PFAFB#30 application, or R5F101PFAFB#30 equivalent, key selection criteria include its 100-pin LFQFP package, absence of data flash, integrated 10-bit ADC (26 channels), dual UART/LIN support, and hardware multiplier/divider - all critical for deterministic real-time control in space-constrained industrial designs.
Technical Context
The R5F101PFAFB#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with dedicated SFR regions enabling efficient peripheral register access.
It integrates a 12-bit interval timer, calendar-capable real-time clock (RTC), watchdog timer, and DMA controller with 4 channels - enabling precise timing coordination, background data movement, and low-CPU-overhead peripheral handling without interrupt latency penalties.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101PFAFB#50 | Identical silicon; differs only in packaging - embossed tape vs. tray (JIS C 0040 compliant) | No functional difference; suited for automated SMT lines requiring tape-and-reel feed | Select #50 for high-volume pick-and-place assembly; #30 for manual prototyping or low-volume production |
| R5F100PFAFB#30 | Same package and pinout, but includes 4 KB data flash memory and operates at −40°C to +85°C (D grade) | Enables embedded data logging without external EEPROM; same industrial temp range | Choose R5F100PFAFB#30 if firmware requires nonvolatile parameter storage; R5F101PFAFB#30 reduces BOM cost where logging is unnecessary |
Compared with R5F101PFAFB#50, the #30 variant offers identical electrical performance with tray packaging for flexible procurement, while R5F100PFAFB#30 adds data flash at the cost of slightly higher unit price - making it preferable only when field-updatable calibration or event logs are required.

FAQ
What is the operating temperature range for the R5F101PFAFB#30?
The R5F101PFAFB#30 is rated for industrial operation from −40°C to +85°C (D grade), validated across the full range for reliable performance in factory automation, HVAC, and outdoor equipment environments. This specification is confirmed in the RL78/G13 datasheet Rev.3.80, Section 1.1.
Does the R5F101PFAFB#30 include data flash memory?
No, the R5F101PFAFB#30 does not include data flash memory. As indicated by the "101" in its part number (per Figure 1-1 of the datasheet), it provides 64 KB of code flash only. For applications requiring embedded nonvolatile parameter storage, R5F100PFAFB#30 (with 4 KB data flash) is the functionally matched alternative.
What package type and pin count does the R5F101PFAFB#30 use?
The R5F101PFAFB#30 uses a 100-pin LFQFP package with 0.5 mm pitch, measuring 14 mm × 14 mm. The "FB" suffix in the part number explicitly denotes this LFQFP-0.5mm variant, and the "P" indicates the 100-pin configuration per the RL78/G13 ordering guide.
Can the R5F101PFAFB#30 operate from a 1.6 V supply?
Yes, the R5F101PFAFB#30 supports single-supply operation from 1.6 V to 5.5 V, enabling direct compatibility with Li-ion, Li-SOCl₂, and alkaline battery systems. At 1.6 V, core frequency is limited per datasheet specifications, but STOP mode current remains at 0.57 μA with RTC active.
How many UART/LIN channels does the R5F101PFAFB#30 support?
The R5F101PFAFB#30 supports up to 4 UART/LIN channels, as specified in the RL78/G13 datasheet Section 1.1. This enables simultaneous communication with multiple peripherals - such as a display (UART0), sensor hub (UART1), and diagnostics interface (LIN) - without external multiplexing.
