Product details
Overview
R5F100PJDFB#X0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit MCU with 192 KB code flash, 8 KB data flash, 16 KB RAM, and operation from −40°C to +85°C. It integrates a 32-MHz RL78 CPU core (41 DMIPS), 16-bit timers (12 channels), 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100PJDFB#X0 datasheet, R5F100PJDFB#X0 pinout, R5F100PJDFB#X0 application, or R5F100PJDFB#X0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, 192 KB flash/8 KB data flash allocation, integrated LIN-capable UARTs for automotive body electronics, and verified support for BGO data flash rewriting during program execution.
Technical Context
The R5F100PJDFB#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four register banks. Its memory subsystem includes 192 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 16 KB RAM - all operating across 1.6–5.5 V supply.
Peripheral integration includes dual DMA controllers (4 channels), 16-bit timer array (12 channels), real-time clock with calendar/alarm/correction, 10-bit ADC with internal reference (1.45 V) and temperature sensor, and three serial interface types: CSI (SPI-compatible), UART/LIN (4 channels), and I²C/Simplified I²C (up to 10 channels).

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100PJDFB#X0?
The R5F100PJDFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas documentation (R01DS0131EJ0380 Rev.3.80).
Does the R5F100PJDFB#X0 support background data flash rewriting while executing application code?
Yes, the R5F100PJDFB#X0 supports background operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory concurrently with data flash erase/write operations - critical for seamless firmware updates or runtime parameter storage without interrupting real-time tasks.
What LIN protocol compliance does the R5F100PJDFB#X0 provide through its UART peripherals?
The R5F100PJDFB#X0 integrates UART modules compliant with LIN 2.2 and ISO 17987-4 specifications when configured in LIN mode. Its hardware supports automatic sync-break detection, checksum calculation, and timing tolerances required for robust automotive sub-network communication - confirmed in the RL78/G13 hardware manual.
How much on-chip RAM is allocated for the flash library during self-programming of the R5F100PJDFB#X0?
The R5F100PJDFB#X0 reserves 256 bytes of RAM starting at address FAF00H for use by the Flash Self-Programming Library during data flash rewriting. This allocation is fixed per device variant and documented in the RL78/G13 Flash Library User's Manual (R20UT2944).
What is the minimum supply voltage and associated low-power mode current for the R5F100PJDFB#X0?
The R5F100PJDFB#X0 operates down to 1.6 V and achieves 0.57 μA typical current in STOP mode with only RTC and LVD enabled. This ultra-low quiescent current enables decade-long battery life in energy-constrained applications such as wireless sensors or portable medical devices.
