Product details
Overview
R5F101GJDFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 192 KB code flash, 8 KB data flash, and 16 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered sensor nodes and smart meters.
For engineers reviewing the R5F101GJDFB#X0 datasheet, R5F101GJDFB#X0 pinout, R5F101GJDFB#X0 application, or R5F101GJDFB#X0 equivalent, key selection criteria include its integrated real-time clock with calendar/alarm, 26-channel 10-bit ADC, dual UART/LIN support, and 16-channel 16-bit timer suite - all validated for -40°C to +105°C operation in industrial control and IoT edge devices.
Technical Context
The R5F101GJDFB#X0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (4 channels), and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes up to 10 I²C/Simplified I²C channels, 8 CSI/SPI channels, and 4 UART/LIN interfaces - all accessible via dedicated SFRs and supported by background operation during data flash rewriting. The device uses a unified 1 MB address space and supports boot swap and flash shield window security functions.
