Product details
Overview
R5F10RBCAFP#50 from Renesas is a 32-pin LQFP 7×7 mm ultra-low-power 16-bit RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver (up to 35 seg × 8 com), and 31 DMIPS performance at 24 MHz. It operates from 1.6 V to 5.5 V and delivers 62.5 µA/MHz active current and 0.64 µA RTC+LVD standby for battery-powered LCD instrumentation.
For engineers reviewing the R5F10RBCAFP#50 datasheet, R5F10RBCAFP#50 pinout, R5F10RBCAFP#50 application, or R5F10RBCAFP#50 equivalent, this device is selected for cost-sensitive, low-power LCD-based embedded systems requiring on-chip timing, analog sensing (10-bit ADC, 10 channels), serial interfaces (UART/I²C/CSI), and functional safety features compliant with IEC/UL 60730.
Technical Context
The R5F10RBCAFP#50 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and CISC instruction set enabling 86% of instructions in 1–2 clock cycles. It integrates a high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature) and supports multiple clock sources including external crystal (X1/X2) and subsystem clock (XT1/XT2).
Its peripheral set includes an 8-channel timer array with RTC (full calendar + alarm), 12-bit interval timer, windowed watchdog, DMA controller (2 channels), and LCD driver supporting capacitor-split, internal-boost, and resistance-division methods - all optimized for single-supply operation and low-voltage retention across −40°C to +85°C ambient.
