Overview
R5F10RFAGFP#30 from Renesas is a 44-pin LQFP, industrial-grade (−40°C to +105°C) RL78/L12 16-bit microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver (up to 39 seg × 4 com), and ultra-low-power operation (0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD instrumentation, smart meters, and industrial HMI panels requiring on-chip timing, analog sensing, and low-voltage robustness.
For engineers reviewing the R5F10RFAGFP#30 datasheet, R5F10RFAGFP#30 pinout, R5F10RFAGFP#30 application, or R5F10RFAGFP#30 equivalent, key selection criteria include its 24 MHz high-speed on-chip oscillator (±1% accuracy), 10-bit ADC with internal 1.45 V reference, 8-channel timer array with RTC calendar/alarm, and dual SPI/I²C/UART interfaces - all within a 10 × 10 mm LQFP package.
Technical Context
The R5F10RFAGFP#30 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and CISC instruction set delivering 31 DMIPS at 24 MHz. Its power management includes multiple low-power modes (Stop, Halt, Snooze), POR/LVD with 14 voltage thresholds, and regulator-capacitor (REGC) support for stable internal voltage generation.
It integrates a full-featured LCD controller supporting capacitor-split, internal-boost, and resistor-division drive methods; up to 44 total I/O pins including 11 dedicated LCD segment/com drivers; and safety features compliant with IEC/UL 60730 including flash CRC, RAM parity, SFR write protection, and illegal memory access detection.
