Product details
Overview
R5F100PLDFB#X0 from Renesas is a 100-pin LFQFP (14 × 14 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 32 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V across –40°C to +105°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), and integrates real-time clock, 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, and DMA - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F100PLDFB#X0 datasheet, R5F100PLDFB#X0 pinout, R5F100PLDFB#X0 application, or R5F100PLDFB#X0 equivalent, key selection considerations include its 100-pin LFQFP-0.5mm package, industrial temperature rating (–40°C to +105°C), integrated data flash with background operation, and support for LIN bus and hardware CRC.
Technical Context
The R5F100PLDFB#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 subsystem clock). It includes on-chip debug, self-programming with boot swap and flash shield window functions, and BGO-capable data flash for concurrent code execution during rewrites.
Power management integrates POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE low-power modes, and dedicated low-speed oscillator for watchdog timer. Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× 12-bit interval timer, and 3× I²C/Simplified I²C channels - all configurable via register-based control logic without external timing components.
