Product details
Overview
R5F100PKDFB#X0 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and operation from −40°C to +85°C. It integrates a 32-MHz RL78 CPU core (41 DMIPS), 16-bit timers (12 channels), 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100PKDFB#X0 datasheet, R5F100PKDFB#X0 pinout, R5F100PKDFB#X0 application, or R5F100PKDFB#X0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, 256 KB code flash with self-programming, 26-channel 10-bit ADC for sensor interfacing, LIN-capable UART for automotive body electronics, and verified operation across industrial temperature range without external regulators.
Technical Context
