It delivers 31 DMIPS at 24 MHz, operates from 1.6 V to 5.5 V, and achieves 0.64 µA RTC+LVD halt current - enabling battery-powered smart meters and portable medical displays.
For engineers reviewing the R5F10RFCAFP#V0 datasheet, R5F10RFCAFP#V0 pinout, R5F10RFCAFP#V0 application, or R5F10RFCAFP#V0 equivalent, key selection criteria include integrated LCD controller (35 seg × 8 com), on-chip 24 MHz ±1% oscillator, 10-bit ADC with internal 1.45 V reference, and IEC 60730 safety features for Class B compliance.
Technical Context
The R5F10RFCAFP#V0 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and CISC instruction set - enabling 86% of instructions in 1–2 clock cycles. Its low-power design integrates voltage regulator (REGC), POR/LVD, and snooze mode for dynamic power scaling.
It embeds an LCD controller supporting capacitor split, internal boost, and resistance division methods with 16-step contrast control and blinking. The peripheral set includes UART, two CSI (SPI-compatible) interfaces, I²C, 8-channel timer array, RTC with calendar/alarm, and DMA with background data flash operation.
