Renesas R5F51306ADFL#30

Overview

R5F51306ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), supporting 10-channel 12-bit A/D conversion in 1.4 µs, dual 8-bit D/A outputs, and capacitive touch sensing for up to 24 keys - deployed in industrial HMI and consumer appliance control systems.

For engineers reviewing the R5F51306ADFL#30 datasheet, R5F51306ADFL#30 pinout, R5F51306ADFL#30 application, or R5F51306ADFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-B, 48-pin LFQFP), confirmed peripheral count (3 SCI channels, 1 RIIC, 1 RSPI, 2 REMC, 2 CMT, 2 CMPB), real-time clock omission, and low-power standby current (0.37 µA) with 4.8 µs wake-up.

Technical Context

The R5F51306ADFL#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling single-cycle 32×32-bit multiply and 64-bit accumulator operations. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and IWDT-dedicated 15 kHz oscillator, with independent ICLK/PCLK/FCLK domains.

Peripheral integration includes ELC for event-driven module chaining without CPU intervention, DTC for interrupt-triggered transfers across four modes, and MPC for flexible pin function assignment. The device omits RTC and REMC per its 48-pin package configuration, as confirmed in Table 1.2 of the datasheet.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51306ADFL#30?

The R5F51306ADFL#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS performance using the 32-bit RXv1 CPU core. Its 5-stage pipeline, single-cycle 32×32-bit multiply, and 64-bit accumulator enable deterministic real-time control. Performance is sustained across the full 1.8–5.5 V supply range, with frequency scaling tied to VCC voltage per datasheet Table 1.1.

Does the R5F51306ADFL#30 include a real-time clock (RTC) module?

No, the R5F51306ADFL#30 does not include an RTC module. As confirmed in Table 1.2 of the datasheet, RTC is supported only in 100-pin and 80-pin RX130 packages; the 48-pin PLQP0048KB-B variant (R5F51306ADFL#30) omits RTC while retaining the sub-clock oscillator (XCIN/XCOUT) for use with the low-power timer (LPT) or custom timing functions.

How many capacitive touch channels does the R5F51306ADFL#30 support?

The R5F51306ADFL#30 supports 24 capacitive touch sensing channels, as specified in Table 1.2 for the 48-pin package. These are implemented via the CTSU module using TS0–TS23 pins, enabling either self-capacitance (24 independent keys) or mutual-capacitance matrix configurations - sufficient for compact appliance control panels without external touch controllers.

What communication interfaces are available on the R5F51306ADFL#30?

The R5F51306ADFL#30 provides three SCI channels (SCI0, SCI5, SCI6), one I2C bus interface (RIIC0), and one serial peripheral interface (RSPI). It does not include SCI12 or REMC units - both are excluded in the 48-pin variant per Table 1.2. All active interfaces support ELC triggering and operate at full 32 MHz PCLKB, enabling concurrent high-speed sensor and actuator communication.

What is the standby current consumption and wake-up time for the R5F51306ADFL#30?

The R5F51306ADFL#30 achieves 0.37 µA supply current in software standby mode with the low-power timer (LPT) active, and recovers to full 32 MHz operation in 4.8 µs. This behavior is measured under VCC = 3.3 V and –40°C to +85°C conditions, and relies on sub-clock or IWDTCLK as the LPT source - enabling ultra-low-power sensing intervals in battery-backed applications.
