Product details
Overview
R5F101PJDFB#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 high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar, and ultra-low-power STOP mode (0.57 μA). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101PJDFB#V0 datasheet, R5F101PJDFB#V0 pinout, R5F101PJDFB#V0 application, or R5F101PJDFB#V0 equivalent, key selection criteria include its data flash omission, LFQFP-100 package compatibility, RTC+LVD low-power retention capability, and support for LIN-bus UART and background data flash programming in other RL78/G13 variants.
Technical Context
The R5F101PJDFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It features dual-clock domains: main system clock (up to 32 MHz) and subsystem clock (32.768 kHz), enabling independent RTC and LVD operation during STOP mode.
It includes 2 DMA channels, 16-bit timer array (12 channels), simplified SPI (CSI), UART/LIN (2 channels), I²C (3 channels), and hardware multiplier/divider. The absence of data flash means firmware must manage nonvolatile storage externally or via code flash wear-leveling.
Key Specifications
