Overview
R5F100ACASP#30 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G13 microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (6 channels), and integrated real-time clock - deployed in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F100ACASP#30 datasheet, R5F100ACASP#30 pinout, R5F100ACASP#30 application, or R5F100ACASP#30 equivalent, key selection criteria include its 30-pin LSSOP-30 package, 16 KB code flash + 4 KB data flash allocation, 10-bit ADC input count, RTC calendar support, and STOP/HALT/SNOOZE power mode sequencing.
Technical Context
The R5F100ACASP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation for data flash rewriting.
Its peripheral set includes up to 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 2–4 channel DMA, and serial interfaces: CSI (SPI-like), UART/LIN, and I²C - all configurable under single-supply 1.6–5.5 V operation across –40°C to +85°C ambient.
