Product details
Overview
R5F51303ADFM#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 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 for industrial control and appliance HMI applications.
For engineers reviewing the R5F51303ADFM#10 datasheet, R5F51303ADFM#10 pinout, R5F51303ADFM#10 application, or R5F51303ADFM#10 equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-C) package, –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, and integrated event link controller (ELC) enabling low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51303ADFM#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 (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and clock accuracy measurement (CAC) for real-time calibration.
Peripheral integration includes MTU2 (6-channel 16-bit timer with complementary PWM), SCIg (3 channels), RIIC (1 channel, up to 400 kbps), RSPI (1 channel, up to 16 Mbps), REMC (2 channels, 4-pattern matching), and CTSU (32-key mutual capacitance support). All operate under ELC-triggered event linkage, allowing autonomous module interaction during CPU sleep.

FAQ
What is the maximum operating frequency and power supply range for the R5F51303ADFM#10?
The R5F51303ADFM#10 operates at a maximum frequency of 32 MHz across a single 1.8 V to 5.5 V supply. Frequency scaling is voltage-dependent: 8 MHz at 1.8–2.4 V, 16 MHz at 2.4–2.7 V, and full 32 MHz above 2.7 V. This enables dynamic power/performance tuning without external regulators. The R5F51303ADFM#10 maintains no-wait-state flash access across all supported frequencies.
Does the R5F51303ADFM#10 support real-time clock (RTC) functionality?
No, the R5F51303ADFM#10 does not include RTC functionality. Per Table 1.2 of the datasheet, RTC is unavailable in 48- and 64-pin RX130 variants-including R5F51303ADFM#10-due to package pin constraints. RTC is only present in 80- and 100-pin versions (e.g., R5F51303ADFN#30 and R5F51303ADFP#30). The R5F51303ADFM#10 retains the low-power timer (LPT) for periodic wake-up events.
How many capacitive touch keys does the R5F51303ADFM#10 support, and what method is used?
The R5F51303ADFM#10 supports up to 32 capacitive touch keys using the mutual capacitance method, implemented via its CTSU module with a 36-pin interface (TS0–TS35 + TSCAP). This configuration enables matrix-based scanning for higher channel density and better noise immunity than self-capacitance. The R5F51303ADFM#10 does not support the 36-key self-capacitance mode, which requires different pin allocation.
What communication interfaces are integrated into the R5F51303ADFM#10?
The R5F51303ADFM#10 integrates three SCIg channels (SCI1, SCI5, SCI6), one I2C bus interface (RIIC0), one RSPI channel, and one SCIh channel (SCI12). It lacks the fourth SCIg channel and second I2C found in larger-package RX130 variants. All interfaces support ELC triggering for autonomous operation. The R5F51303ADFM#10 does not include CAN, USB, or Ethernet peripherals.
Is the R5F51303ADFM#10 qualified for industrial temperature operation?
Yes, the R5F51303ADFM#10 is rated for industrial temperature operation from –40°C to +85°C, indicated by the "D" suffix in its part number. It is not rated for extended temperature (–40°C to +105°C), which requires the "G" suffix variant (e.g., R5F51303AGFM#30). The R5F51303ADFM#10 meets JEDEC JESD22-A108 reliability standards for this temperature range.
