Product details
Overview
R5F100JCGFA#X0 from Renesas is a 52-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and targets battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100JCGFA#X0 datasheet, R5F100JCGFA#X0 pinout, R5F100JCGFA#X0 application, or R5F100JCGFA#X0 equivalent, key selection criteria include ultra-low-power operation (66 μA/MHz), integrated RTC with alarm/calendar, on-chip debug, self-programming flash with boot swap, and 52-pin LQFP package compatibility with industrial temperature range (−40°C to +105°C).
Technical Context
The R5F100JCGFA#X0 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), UART/LIN (up to 4 channels), I²C (up to 10 channels), and CSI (SPI-compatible serial interface) for flexible peripheral interfacing.
Power management includes HALT, STOP, and SNOOZE low-power modes, on-chip POR and LVD with 14 selectable voltage detection levels, and DMA controller with 4 channels enabling efficient memory-to-peripheral transfers in 2 clocks per 8/16-bit transfer. The device supports background operation during data flash rewriting (BGO) and features a high-accuracy ±1.0% on-chip oscillator across 1–32 MHz.
