Product details
Overview
R5F51306BDFL#30 from Renesas is a 32-bit RX130 Group microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS) across 1.8–5.5 V supply. It integrates a 12-bit A/D converter (10 channels), two 8-bit D/A outputs, capacitive touch sensing (24 keys), RTC, low-power timer, and dual SCI/I²C/RSPI interfaces - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F51306BDFL#30 datasheet, R5F51306BDFL#30 pinout, R5F51306BDFL#30 application, or R5F51306BDFL#30 equivalent, key selection criteria include its 48-pin LFQFP package (PLQP0048KB-B), –40°C to +85°C temperature grade, IEC60730-compliant self-test features, and support for event-driven low-power operation via ELC and software standby mode (0.37 µA).
Technical Context
The R5F51306BDFL#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling single-cycle 32×32 multiply and 64-bit accumulator operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven autonomy: ELC links 47 event sources directly to modules (e.g., MTU, A/D) without CPU intervention; DTC supports chain transfers triggered by interrupts; and REMC (not present in 48-pin variant) is omitted per Table 1.2, while CTSU retains 24-channel capacitive touch capability.

FAQ
What is the maximum operating frequency and power supply range for the R5F51306BDFL#30?
The R5F51306BDFL#30 operates at a maximum frequency of 32 MHz across a single 1.8 V to 5.5 V supply rail. Its voltage-frequency scaling is tiered: 8 MHz at 1.8–2.4 V, 16 MHz at 2.4–2.7 V, and full 32 MHz only above 2.7 V - ensuring reliable operation under varying input conditions while minimizing active power draw.
Does the R5F51306BDFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F51306BDFL#30 includes hardware-assisted self-test features required for IEC60730 Class B: A/D converter diagnostics, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) validation, RAM test support via DOC, and analog input disconnection detection - enabling certified safety firmware without external components.
How many capacitive touch channels does the R5F51306BDFL#30 support, and what is the physical pin mapping?
The R5F51306BDFL#30 supports 24 capacitive touch sensing channels via its CTSU module, mapped to TS0 through TS23. These pins are multiplexed general-purpose I/Os and require no external RC networks - each can be configured as a standalone electrode for self-capacitance measurement in space-constrained HMI layouts.
What communication interfaces are available on the R5F51306BDFL#30, and which are excluded compared to larger RX130 variants?
The R5F51306BDFL#30 provides SCI (3 channels), I²C (1 channel), and RSPI (1 channel). It omits SCI12 (LIN-capable), REMC (remote control receiver), and the fourth SCI channel found in 64+ pin variants - consistent with its 48-pin package limitations per Table 1.2 of the datasheet.
What is the endurance and access method for the on-chip data flash in the R5F51306BDFL#30?
The R5F51306BDFL#30 includes 8 KB of on-chip data flash rated for 1,000,000 program/erase cycles (typical).
