Technical Context

The R5F52305AGFP#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit single-precision FPU, 88.56 DMIPS performance at 54 MHz, and Harvard architecture with 5-stage pipeline. It supports little-endian data arrangement and includes memory protection unit (MPU) for safety-critical execution.

Its clock system integrates main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL enabling concurrent 54 MHz system clock and 48 MHz USB clock. Real-time clock (RTCe) operates on sub-clock with calendar mode, alarm, and time-capture functions.

FAQ

What is the maximum operating frequency of the R5F52305AGFP#30?

The R5F52305AGFP#30 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance. This speed is achievable across its full 1.8–5.5 V supply range, with no wait states on SRAM and accelerated flash access via ROM accelerator hit. The R5F52305AGFP#30 uses a PLL-based clock generation circuit that accepts 4–12.5 MHz input to generate the 54 MHz ICLK.

Does the R5F52305AGFP#30 include a CAN interface?

Yes, the R5F52305AGFP#30 integrates a single-channel RSCAN module compliant with ISO11898-1, supporting data rates up to 1 Mbps and 16 configurable message boxes. This CAN interface is fully functional in the G-version part and is electrically isolated from USB and other high-speed peripherals via dedicated clock domains. The R5F52305AGFP#30 provides CAN_TX and CAN_RX pins on dedicated package terminals for direct connection to an external CAN transceiver.

What is the flash memory capacity of the R5F52305AGFP#30?

The R5F52305AGFP#30 contains 128 KB of on-chip flash memory for program code and constants. It supports in-system programming via USB or asynchronous serial interface, and features background operation (BGO) allowing code execution during flash write/erase cycles. The R5F52305AGFP#30 flash is rated for 100,000 program/erase cycles and operates down to 1.8 V, enabling low-voltage field updates without external power rail changes.

Is the R5F52305AGFP#30 qualified for automotive temperature ranges?

Yes, the R5F52305AGFP#30 is the G-version part, qualified for operation from −40°C to +105°C ambient temperature. This qualification aligns with AEC-Q100 stress test requirements for Grade 2 automotive components and supports deployment in under-hood and cabin control modules. The R5F52305AGFP#30 maintains full functionality - including USB, CAN, and CTSU - across this extended range without derating.

Does the R5F52305AGFP#30 support USB On-The-Go (OTG)?

Yes, the R5F52305AGFP#30 includes a USB 2.0 host/function/OTG module compliant with USB specification v2.0. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, and Battery Charging Specification 1.2 (BC1.2). The R5F52305AGFP#30 integrates internal USB transceiver termination and VCC_USB power generation - eliminating need for external USB PHY or charge-pump circuitry.
