Overview
R5F100LCAFB#10 from Renesas is a 64-pin, LFQFP-0.5 mm pitch, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LCAFB#10 datasheet, R5F100LCAFB#10 pinout, R5F100LCAFB#10 application, or R5F100LCAFB#10 equivalent, key selection criteria include its integrated real-time clock with calendar support, 26-channel 10-bit ADC, 16-channel 16-bit timer suite, and hardware UART/LIN, SPI, and I²C interfaces for embedded control and telemetry systems.
Technical Context
The R5F100LCAFB#10 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), and features a 1 MB address space with four banks of 8-bit general-purpose registers.
It integrates on-chip peripherals including a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, background operation-capable data flash (1M rewrite cycles), and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time response in resource-constrained environments.
