Product details
Overview
R5F100LCAFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 512 KB flash, 8 KB data flash, and 32 KB RAM, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100LCAFB#30 datasheet, R5F100LCAFB#30 pinout, R5F100LCAFB#30 application, or R5F100LCAFB#30 equivalent, key selection criteria include industrial-grade temperature support, integrated data flash with 1M rewrite cycles, background operation during program execution, real-time clock with calendar/alarm, and hardware DMA for sensor/data acquisition systems.
Technical Context
The R5F100LCAFB#30 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 features on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog timer operation.
Power management includes HALT, STOP, and SNOOZE modes; voltage detector (LVD) with 14 interrupt/reset levels; and POR circuit. Memory subsystem comprises 512 KB code flash (1 KB block size), 8 KB data flash with BGO capability, and 32 KB RAM - all accessible under single-supply 1.6–5.5 V operation.
