Product details
Overview
R5F51305ADNE#20 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (10 channels), two 8-bit D/A outputs, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions - deployed in low-power consumer appliance control and industrial HMI interfaces.
For engineers reviewing the R5F51305ADNE#20 datasheet, R5F51305ADNE#20 pinout, R5F51305ADNE#20 application, or R5F51305ADNE#20 equivalent, key selection criteria include its 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch), –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, and integrated event-link controller (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51305ADNE#20 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiplication. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and clock accuracy measurement circuit (CAC) for real-time calibration.
Power management includes three low-power modes - sleep, deep sleep, and software standby (0.37 µA, 4.8 µs wake-up) - supported by low-power timer (LPT) and module stop control. Peripheral coordination uses Event Link Controller (ELC) to trigger MTU, RTC, or A/D conversion without CPU intervention.
