Renesas R5F51307ADFN#10

Overview

R5F51307ADFN#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller with 384 KB flash, 48 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), supporting capacitive touch sensing (36 channels), 12-bit A/D (17 channels), dual 8-bit D/A, RTC, and IEC60730-compliant safety features for industrial control panels and appliance HMI systems.

For engineers reviewing the R5F51307ADFN#10 datasheet, R5F51307ADFN#10 pinout, R5F51307ADFN#10 application, or R5F51307ADFN#10 equivalent, this page delivers verified package mapping (PLQP0080KB-B, 80-pin LFQFP), validated peripheral configuration (MTU2 ×6, SCIg ×3, RIIC ×1, RSPI ×1), confirmed low-power modes (software standby: 0.37 µA, 4.8 µs wake-up), and real-world design constraints including 1.8–5.5 V supply, –40 to +85°C operation, and ESD-tolerant I/O.

Technical Context

The R5F51307ADFN#10 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32 multiply. Its clock system integrates high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and CAC for frequency accuracy monitoring.

Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention-critical for deterministic motor control and low-latency sensor response. The Data Transfer Controller (DTC) supports chain transfer across four interrupt sources, while Multi-function Pin Controller (MPC) allows dynamic I/O function assignment per pin.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51307ADFN#10?

The R5F51307ADFN#10 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS (Dhrystone MIPS) performance using the 32-bit RXv1 CPU core. Its 5-stage pipeline, single-cycle 32×32 multiply, and variable-length instruction set enable efficient code density and deterministic real-time execution-verified in Renesas R01DS0273EJ0300 Rev.3.00.

Does the R5F51307ADFN#10 support capacitive touch sensing, and how many keys can it handle?

Yes, the R5F51307ADFN#10 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 36 self-capacitance keys (one pin per key) or 324 mutual-capacitance keys (matrix configuration). This capability is confirmed for the 80-pin PLQP0080KB-B package in Table 1.2 of the R5F51307ADFN#10 datasheet (R01DS0273EJ0300), making it suitable for touch-enabled appliance interfaces without external controllers.

What are the low-power consumption characteristics of the R5F51307ADFN#10 in software standby mode?

In software standby mode, the R5F51307ADFN#10 draws only 0.37 µA (typical) and recovers in 4.8 µs-enabled by the Low Power Timer (LPT) running off the sub-clock or IWDT-dedicated oscillator. This behavior is specified in Section 1.1 of R01DS0273EJ0300 and validated for the D-version (–40 to +85°C) device, supporting battery-operated sensor nodes and energy-efficient HMI designs.

Which communication interfaces are available on the R5F51307ADFN#10, and how many channels does each support?

The R5F51307ADFN#10 provides three SCIg channels (SCI1, SCI5, SCI6), one SCIh channel (SCI12), one I²C bus interface (RIIC0), and one Serial Peripheral Interface (RSPI). Per Table 1.2 in R01DS0273EJ0300, the 80-pin variant supports these exact counts-no SCI0/SCI8/SCI9 or second RIIC channel. All interfaces support ELC-triggered operation for CPU-free data transfers.

What is the flash and SRAM capacity of the R5F51307ADFN#10, and is background programming supported?

The R5F51307ADFN#10 contains 384 KB of on-chip flash memory and 48 KB of SRAM, both operating with zero wait states at 32 MHz. It also includes 8 KB of data flash with Background Operation (BGO) support-allowing concurrent program/erase cycles and CPU execution, as documented in Section 1.1 and Section 22 of R01DS0273EJ0300 Rev.3.00.
