Product details
Overview
R5F101PGAFB#10 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, no data flash, and industrial-grade operation up to +105°C - designed for battery-powered sensor nodes, smart meters, and embedded control requiring RTC, ADC, and multiple serial interfaces.
For engineers reviewing the R5F101PGAFB#10 datasheet, R5F101PGAFB#10 pinout, R5F101PGAFB#10 application, or R5F101PGAFB#10 equivalent, key selection criteria include its 96 KB code flash / 8 KB RAM allocation, absence of on-chip data flash, LFQFP-100 package with 0.5-mm pitch, -40°C to +105°C industrial temperature grade (G suffix), and support for UART/LIN, I²C, CSI, 16-bit timers, and 10-bit ADC across 26 channels.
Technical Context
The R5F101PGAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.
Its analog subsystem includes a 10-bit A/D converter with 26 input channels, internal 1.45 V reference, and integrated temperature sensor (enabled only in HS mode); digital peripherals include up to 10 I²C/Simplified I²C channels, 4 UART/LIN interfaces, and 8 CSI (SPI-compatible) channels - all operating within 1.6–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC CPU with 3-stage pipeline and variable instruction timing |

FAQ
What is the flash and RAM configuration of the R5F101PGAFB#10?
The R5F101PGAFB#10 features 96 KB of code flash memory and 8 KB of on-chip RAM. It does not include data flash memory - unlike the R5F100xx series - so nonvolatile parameter storage requires external EEPROM or FRAM. This configuration targets applications where firmware size exceeds 64 KB but runtime data logging is handled externally or via backup registers.
Does the R5F101PGAFB#10 support data flash programming during runtime?
No, the R5F101PGAFB#10 does not include data flash memory and therefore lacks background data flash programming (BGO) capability. Its flash library supports only code flash self-programming. For applications requiring field-updatable parameters, designers must integrate external nonvolatile memory and manage write endurance and wear leveling in firmware.
What is the operating temperature range and qualification grade of the R5F101PGAFB#10?
The R5F101PGAFB#10 is rated for -40°C to +105°C operation and carries the 'G' suffix, indicating industrial-grade qualification per Renesas specifications. This makes it suitable for under-hood automotive modules, industrial PLC I/O, and outdoor utility equipment where extended thermal resilience is mandatory.
Which serial communication interfaces are available on the R5F101PGAFB#10?
The R5F101PGAFB#10 supports up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. These interfaces can operate concurrently, enabling simultaneous communication with displays, sensors, radio modules, and legacy industrial buses - all while maintaining low-power operation via peripheral clock gating.
Is the R5F101PGAFB#10 pin-compatible with other RL78/G13 100-pin variants?
Yes, the R5F101PGAFB#10 shares identical pinout and package (100-pin LFQFP, 0.5 mm pitch) with all other RL78/G13 devices in the same pin-count group, including R5F100PGAFB#10 and R5F101PJAFB#10. This allows drop-in replacement within the same memory/peripheral subset, provided firmware accounts for differences in flash size, RAM, and data flash presence.
