Product details
Overview
R5F100JCGFA#V0 from Renesas is a 52-pin LQFP-0.65mm, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 256 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (24 channels), UART/I²C/CSI interfaces, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode). It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100JCGFA#V0 datasheet, R5F100JCGFA#V0 pinout, R5F100JCGFA#V0 application, or R5F100JCGFA#V0 equivalent, key selection criteria include its G-grade temperature rating, 52-pin LQFP package with 24-channel analog input support, background data flash rewriting capability, and hardware real-time clock with calendar and alarm functions.
Technical Context
The R5F100JCGFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer, and DMA controller with 4 channels for efficient peripheral-to-memory transfers in 2 clock cycles.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable). The device supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates without external programming hardware.
