Overview
R5F100LFABG#U0 from Renesas is a 64-pin VFBGA-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 12-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI) for embedded control in industrial temperature range (−40°C to +105°C).
For engineers reviewing the R5F100LFABG#U0 datasheet, R5F100LFABG#U0 pinout, R5F100LFABG#U0 application, or R5F100LFABG#U0 equivalent, key selection criteria include its VFBGA-64 package footprint, industrial-grade thermal rating, integrated data flash rewrite capability (1M cycles), low-voltage operation down to 1.6 V, and hardware-accelerated peripheral set optimized for battery-powered and space-constrained industrial sensing and actuation.
Technical Context
The R5F100LFABG#U0 implements the RL78 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), and includes on-chip debug, self-programming with boot swap, and background operation during data flash rewriting.
It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, watchdog timer with dedicated low-speed oscillator, DMA controller (4 channels), and 16-bit × 16-bit multiply-accumulate unit - all designed for deterministic real-time control in resource-constrained environments without external timing or memory support.
Key Specifications
