Product details
Overview
R5F100MKAFB#V0 from Renesas is an RL78/G13 80-pin, 384 KB flash, 8 KB data flash, 20 KB RAM ultra-low-power 16-bit MCU operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with 66 μA/MHz active current and RTC+LVD standby at 0.57 μA - used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100MKAFB#V0 datasheet, R5F100MKAFB#V0 pinout, R5F100MKAFB#V0 application, or R5F100MKAFB#V0 equivalent, key selection criteria include integrated RTC with calendar/alarm, background data flash rewriting (1M write cycles), 16-bit A/D converter with 26-channel input, and LFQFP-80 (12 × 12 mm, 0.5-mm pitch) package compatibility for space-constrained control modules.
Technical Context
The R5F100MKAFB#V0 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 integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
It features a 2-channel DMA controller (2-cycle transfer between SFR and RAM), 16×16→32-bit multiplier/accumulator, and mixed-signal peripherals including 12-bit interval timer, real-time clock with calendar and correction, and 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor.
