Product details
Overview
R5F100PJAFA#X0 from Renesas is a 100-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces. It operates from 1.6 V to 5.5 V and delivers 41 DMIPS at 32 MHz for embedded control in HVAC, motor drives, and smart appliances.
For engineers reviewing the R5F100PJAFA#X0 datasheet, R5F100PJAFA#X0 pinout, R5F100PJAFA#X0 application, or R5F100PJAFA#X0 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C industrial temperature grade, 256 KB code flash with self-programming, 26-channel 10-bit ADC, and hardware LIN support - all critical for resource-constrained, low-power industrial control designs.
Technical Context
The R5F100PJAFA#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-power mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Power management includes HALT, STOP, and SNOOZE modes enabling 66 μA/MHz active current and 0.57 μA RTC+LVD retention. Memory subsystem features background operation (BGO) for data flash rewriting while executing program code, plus flash shield window and boot swap functions for secure firmware updates.
