Renesas R5F51308AGFN#30

Overview

R5F51308AGFN#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), two 8-bit D/A outputs, capacitive touch sensing (36 channels), and IEC60730-compliant safety functions for industrial control and consumer HMI applications.

For engineers reviewing the R5F51308AGFN#30 datasheet, R5F51308AGFN#30 pinout, R5F51308AGFN#30 application, or R5F51308AGFN#30 equivalent, key selection criteria include its −40°C to +105°C extended temperature rating, 80-pin LFQFP package (PLQP0080KB-B), integrated RTC and low-power timer, and support for event-driven peripheral operation via ELC without CPU wake-up.

Technical Context

The R5F51308AGFN#30 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its on-chip clock system includes high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and clock accuracy measurement circuit (CAC) for real-time calibration.

Peripheral coordination is managed by the Event Link Controller (ELC), which enables direct module-to-module triggering-e.g., MTU timer events initiating A/D conversion-while the CPU remains in deep sleep. The Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes activated by 47 configurable event sources.

FAQ

What is the maximum operating frequency and voltage range supported by the R5F51308AGFN#30?

The R5F51308AGFN#30 operates at up to 32 MHz when powered from 2.7 V to 5.5 V, 16 MHz at 2.4–2.7 V, and 8 MHz at 1.8–2.4 V. Its high-speed on-chip oscillator delivers 32 MHz ±1% accuracy, and flash memory accesses incur zero wait states across the full speed range. This ensures deterministic real-time performance in thermally demanding environments up to +105°C.

Does the R5F51308AGFN#30 include hardware support for functional safety standards like IEC60730?

Yes, the R5F51308AGFN#30 integrates dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic A/D converter tests, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via the Data Operation Circuit (DOC), and analog input disconnection detection. These are documented in the hardware manual and supported by Renesas' safety application notes.

How many capacitive touch channels does the R5F51308AGFN#30 support, and what configurations are available?

The R5F51308AGFN#30 includes a dedicated Capacitive Touch Sensing Unit (CTSUa) supporting up to 36 channels. It operates in self-capacitance mode (one pin per key, up to 36 keys) or mutual-capacitance matrix mode (36 pins forming up to 324 keys). The unit provides hardware-accelerated scanning, noise suppression, and automatic baseline adjustment-enabling robust touch interfaces without CPU overhead.

What communication interfaces are integrated into the R5F51308AGFN#30, and how many instances of each are available?

The R5F51308AGFN#30 integrates seven Serial Communications Interface (SCI) channels (six SCIg + one SCIh), one I²C bus interface (RIICa), one Serial Peripheral Interface (RSPIa), and one Remote Control Signal Receiver (REMC) with two units. SCI supports UART, SPI, I²C, LIN, and smart card modes; RSPI achieves up to 16 Mbps; RIIC complies with SMBus and fast-mode I²C (400 kbps).

What is the package type and pin count of the R5F51308AGFN#30, and is it pin-compatible with other RX130 variants?

The R5F51308AGFN#30 uses an 80-pin LFQFP package (PLQP0080KB-B), measuring 12 × 12 mm with 0.5 mm pitch. It is pin-compatible with other RX130 Group members in the same 80-pin footprint-including R5F51308ADFN#30 and R5F51307AGFN#30-but not with 48-, 64-, or 100-pin variants due to differing peripheral mappings and I/O counts.
