Product details
Overview
R5F100MLAFA#30 from Renesas is an RL78/G13 16-bit low-power MCU with 512 KB flash, 32 KB RAM, and 80-pin LQFP-0.65mm package, operating from 1.6–5.5 V at -40°C to +85°C (Industrial A-grade), delivering 41 DMIPS @ 32 MHz while consuming only 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100MLAFA#30 datasheet, R5F100MLAFA#30 pinout, R5F100MLAFA#30 application, or R5F100MLAFA#30 equivalent, key selection criteria include its integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, dual UART/LIN support, and hardware multiplier/divider for deterministic control-loop execution in resource-constrained embedded systems.
Technical Context
The R5F100MLAFA#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock), and features a unified 1 MB address space with four register banks of eight 8-bit registers each.
It integrates on-chip peripherals including up to 16 × 16-bit timers, one 12-bit interval timer, one calendar-capable RTC, one watchdog timer, two to four DMA channels, and serial interfaces comprising CSI (SPI-compatible), UART/LIN, and I²C - all configurable via dedicated SFRs without external glue logic.
