Product details
Overview
R5F101PJAFB#V0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit MCU with 96 KB flash, 8 KB RAM, no data flash, and -40°C to +85°C operation. It integrates a 32-MHz RL78 CPU core (41 DMIPS), 16-bit timers (12 channels), 10-bit 26-channel ADC, RTC, UART/LIN, I²C, and CSI interfaces - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F101PJAFB#V0 datasheet, R5F101PJAFB#V0 pinout, R5F101PJAFB#V0 application, or R5F101PJAFB#V0 equivalent, key selection criteria include its data-flash-free configuration, LFQFP-100 package with 0.5-mm pitch, industrial temperature range, and support for low-power SNOOZE/STOP modes down to 0.57 μA.
Technical Context
The R5F101PJAFB#V0 implements the RL78 CISC core with 3-stage pipeline, configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), and 1 MB address space. It supports background data flash operations only in data-flash-equipped variants - this part omits data flash entirely, relying on code flash for firmware storage and parameter retention via software-managed EEPROM emulation.
Its peripheral set includes 12 × 16-bit timers (with interval timer and RTC), 26-channel 10-bit ADC with internal 1.45-V reference and temperature sensor, and three serial interface types: CSI (SPI-compatible), UART/LIN (4 channels), and I²C (up to 10 channels). Power management features HALT, STOP, and SNOOZE modes with LVD interrupt/reset across 14 voltage levels.

FAQ
Does R5F101PJAFB#V0 include data flash memory?
No, R5F101PJAFB#V0 does not include data flash memory. The "101" in the part number explicitly denotes absence of data flash per Renesas' RL78/G13 naming convention. It provides 96 KB of code flash only, with parameter storage implemented via software-emulated EEPROM in code flash or external memory.
What is the maximum operating frequency and corresponding DMIPS rating for R5F101PJAFB#V0?
R5F101PJAFB#V0 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, confirmed in the RL78/G13 datasheet Rev. 3.80.
Which serial communication interfaces are supported by R5F101PJAFB#V0?
R5F101PJAFB#V0 supports three serial interface families: up to 4 UART/LIN channels (with LIN 2.1/2.2A compliance), up to 10 I²C/Simplified I²C channels, and 2–8 CSI channels compatible with SPI protocols. All are independently configurable and share no fixed pin conflicts in the 100-pin LFQFP package.
What power-saving modes are available on R5F101PJAFB#V0, and what is the lowest achievable current draw?
R5F101PJAFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA - verified across –40°C to +85°C. This enables multi-year operation on primary lithium batteries in metering and sensor applications.
