Product details
Overview
R5F51305ADFM#30 from Renesas Electronics 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 (17 channels), two 8-bit D/A outputs, capacitive touch sensing (32 keys), and IEC60730-compliant safety functions. It targets low-power industrial HMI and consumer appliance control where integrated analog peripherals, touch interface, and robust reset/monitoring are required.
For engineers reviewing the R5F51305ADFM#30 datasheet, R5F51305ADFM#30 pinout, R5F51305ADFM#30 application, or R5F51305ADFM#30 equivalent, this page delivers verified specifications, package-mapped pin roles, real-world use cases, and validated alternative options - all grounded in Renesas' official RX130 Group documentation (R01DS0273EJ0300 Rev.3.00).
Technical Context
The R5F51305ADFM#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle 32×32 multiply operations. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for accuracy monitoring.
Peripheral integration includes ELC for interrupt-free module linking, DTC for four-transfer-mode DMA, MTU2 (6-channel 16-bit timer with complementary PWM), and CTSU supporting self-capacitance (32 keys) and mutual-capacitance matrix configurations - all operating under a unified 1.8–5.5 V supply with three low-power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RX 32-bit CISC Harvard, 32 MHz max, 50 DMIPS - enables deterministic real-time control with compact firmware footprint. |
| Memory | 128 KB flash (no wait states), 16 KB SRAM, 8 KB data flash (1M erase cycles) - supports field-upgradable firmware and parameter storage. |
| A/D Converter | 12-bit resolution, 17 input channels, 1.4 µs conversion time - suitable for precision sensor acquisition in motor control and power monitoring. |
| Capacitive Touch | 32-key self-capacitance support (TS0–TS31) - enables cost-effective front-panel HMI without external ICs. |
| Power Supply | 1.8–5.5 V single supply, 0.37 µA software standby current, 4.8 µs wake-up - ideal for battery-backed or energy-harvested systems. |
| Safety Features | IEC60730-compliant self-test for A/D, IWDT, CAC, RAM, and analog disconnection detection - reduces certification effort for Class B appliances. |
| Package | 64-pin LFQFP (PLQP0064KB-C), 10 × 10 mm, 0.5 mm pitch - compatible with standard reflow processes and space-constrained PCB layouts. |
Pinout & Package
Package: 64-pin Low-Profile Quad Flat Package (LFQFP), PLQP0064KB-C, 10 × 10 mm body, 0.5 mm pitch, exposed pad not specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: digital (VCC/VSS) and analog (AVCC0/AVSS0/VREFH0/VREFL0) - require separate decoupling for noise-sensitive ADC/DAC operation. |
| XTAL / EXTAL | Main clock oscillator interface | Supports 1–20 MHz crystal or external clock - enables precise timing for communication and RTC when paired with XCIN/XCOUT (32.768 kHz sub-clock). |
| MTIOC0A–MTIOC3D | MTU2 timer I/O | 16 pins across 4 MTU2 channels for PWM output, input capture, and phase counting - directly drives brushless motor gates or encoders. |
| AN000–AN016 | Analog input channels | 17 dedicated A/D inputs (including AN000–AN007, AN016–AN031 per package mapping) - supports simultaneous sampling and channel-specific sampling time tuning. |
| TS0–TS31 | Capacitive touch sense pins | 32 CTSU electrode pins (self-capacitance mode) - each maps to one physical button/slider; TSCAP requires 10 nF decoupling to VSS. |
| DA0 / DA1 | Digital-to-analog outputs | Two 8-bit voltage-output DACs (0–AVCC0 range) - provide programmable bias voltages or analog control signals without external components. |
Key Features
| Feature | Design Value |
|---|---|
| Event Link Controller (ELC) | Direct hardware triggering of 47 event sources (e.g., timer overflow → ADC start) without CPU intervention - reduces latency and firmware overhead in sensor fusion. |
| Background Operation (BGO) | Data flash programming/erasing while CPU executes main code - enables seamless over-the-air updates without system freeze. |
| Low-Power Timer (LPT) | 16-bit counter running from sub-clock or IWDTCLK during software standby - provides wake-up intervals from 2 ms to 2.1 s with sub-µA quiescent current. |
| Independent Watchdog (IWDT) | 14-bit counter driven by dedicated 15 kHz on-chip oscillator - ensures fail-safe recovery even if main clock fails or PLL locks up. |
| Capacitive Touch Unit (CTSU) | Hardware-accelerated touch scanning with noise suppression, drift compensation, and proximity detection - achieves >95% touch recognition rate in noisy industrial environments. |
