Product details
Overview
R5F51305ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller in the RX130 Group, 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 (17 channels), two 8-bit D/A channels, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions. It targets low-power industrial and consumer HMI applications requiring integrated analog peripherals and robust real-time control.
For engineers reviewing the R5F51305ADFL#30 datasheet, R5F51305ADFL#30 pinout, R5F51305ADFL#30 application, or R5F51305ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-B) package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and support for event-driven peripheral coordination via ELC without CPU intervention.
Technical Context
The R5F51305ADFL#30 implements a CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for high-efficiency signal processing. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for accuracy monitoring - all configurable per domain (ICLK/PCLK/FCLK).
Peripheral integration includes MTU2 (6-channel 16-bit timer with complementary PWM), SCIg (3 channels), RIIC (1 channel), RSPI (1 channel), REMC (2 channels), and CTSU (24-key capacitive touch). The ELC enables direct inter-module triggering (e.g., timer → ADC start), while DTC supports interrupt-driven transfers across 47 event sources - critical for deterministic low-power sensor hub operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: PLQP0048KB-B - 48-pin Low-Profile Quad Flat Package, 7 mm × 7 mm, 0.5 mm pitch, lead-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Single 1.8–5.5 V rail powers digital and analog sections; separate AVCC0/AVSS0 pins isolate noise-sensitive ADC/DAC domains. |

| DA0 / DA1 | Analog output | Two independent 8-bit voltage outputs referenced to AVCC0 - suitable for generating reference voltages or driving analog actuators. |
| TS0–TS23 | Capacitive touch sense pins | 24 GPIOs configured as CTSU electrodes - supports matrix or linear touch layouts with built-in noise immunity and auto-calibration. |
| SCI0_RXD / SCI0_TXD | Asynchronous serial interface | Full-duplex UART with fine-adjustable baud rate (0–255/255) - enables reliable communication with displays, sensors, or host controllers over noisy industrial lines. |
Key Features
| Feature | Design Value |
|---|---|

| Data Transfer Controller (DTC) | Four transfer modes (normal, repeat, block, chain) activated by interrupts - offloads memory-to-peripheral transfers (e.g., ADC buffer → RAM), freeing CPU for control tasks. |
| Capacitive Touch Sensing Unit (CTSU) | 24-key self-capacitance support with automatic drift compensation - enables robust touch interfaces in humid or dusty environments without shielded cables or external ICs. |
| IEC60730 Safety Functions | Integrated RAM test assistance, ADC self-test, clock accuracy measurement, and IWDT disconnection detection - reduces external component count and validation effort for safety-critical appliances. |
| Low-Power Timer (LPT) | 16-bit counter running on sub-clock or IWDTCLK during software standby - maintains accurate timekeeping and periodic wake-up events while consuming only 0.37 µA. |
