Overview
R5F51303AGFL#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller optimized for low-power, touch-enabled consumer and industrial applications. It operates at up to 32 MHz (50 DMIPS), integrates 64 KB flash, 10 KB SRAM, 8 KB data flash, dual 8-bit DACs, 12-bit ADC with 17 channels, capacitive touch sensing (24 keys), and supports –40°C to +105°C operation in a 48-pin LFQFP package.
For engineers reviewing the R5F51303AGFL#10 datasheet, R5F51303AGFL#10 pinout, R5F51303AGFL#10 application, or R5F51303AGFL#10 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts - all grounded in Renesas' official R01DS0273EJ0300 Rev.3.00 documentation.
Technical Context
The R5F51303AGFL#10 implements the 32-bit RXv1 core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling 1-cycle instruction execution and 50 DMIPS at 32 MHz. Its on-chip peripherals include MTU2 (6-channel 16-bit timer), CMT (2-channel 16-bit compare match), TMR (4-channel 8-bit timer), LPT (16-bit low-power timer), and ELC for event-driven peripheral coordination without CPU intervention.
It features dual-clock domain operation: ICLK (system clock, max 32 MHz), PCLKB (peripheral clock, max 32 MHz), and FCLK (FlashIF clock, max 32 MHz), with independent scaling. Power management includes three low-power modes, 0.37 µA software standby current, and 4.8 µs wake-up time - all supported by integrated LVD circuits and IWDT with dedicated 15 kHz oscillator.
