It operates at up to 54 MHz (88.56 DMIPS), integrates 384 KB on-chip flash, 32 KB SRAM, 8 KB data flash, a 12-bit 24-channel ADC (0.83 µs conversion), and dual 12-bit DACs. It supports USB 2.0 full-speed host/function/OTG, CAN, SCI, I²C, RSPI, and capacitive touch sensing - deployed in smart home controllers and industrial HMI panels.

For engineers reviewing the R5F52317AGNE#00 datasheet, R5F52317AGNE#00 pinout, R5F52317AGNE#00 application, or R5F52317AGNE#00 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm) package, −40 to +105°C operating range (G version), integrated TSIP-Lite encryption engine (AES-128/256), RTC with battery backup support, and ELC-driven low-power event-triggered operation without CPU wake-up.

Technical Context

The R5F52317AGNE#00 belongs to the RX231 Group and implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 32×32-bit hardware multiplier, and 32-bit divider (2-cycle min). Its memory subsystem includes no-wait SRAM at 54 MHz, flash with ROM accelerator, and background operation (BGO) for data flash writes during code execution.

Peripherals are orchestrated via the Event Link Controller (ELC), enabling direct inter-module triggering (e.g., timer → ADC start) while the CPU remains in deep sleep. The MCU supports three low-power modes - sleep, deep sleep, and software standby - with the low-power timer (LPT) active in standby using the 32.768 kHz sub-clock or IWDT oscillator.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52317AGNE#00?

The R5F52317AGNE#00 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS. Its RXv2 CPU core includes a 32-bit hardware multiplier, 32-bit divider (2-cycle minimum), and IEEE 754-compliant single-precision FPU - enabling deterministic floating-point math for real-time control loops without software emulation overhead in the R5F52317AGNE#00.

Does the R5F52317AGNE#00 support USB host functionality, and what are the electrical requirements?

Yes, the R5F52317AGNE#00 integrates a USB 2.0 full-speed host/function/OTG module with an on-chip transceiver. It supports 12 Mbps operation and requires only USB_DP and USB_DM pins with standard 27 Ω series resistors. When VCC is 4.0–5.5 V, the internal USB regulator powers VCC_USB - eliminating the need for an external 3.3 V USB supply in the R5F52317AGNE#00 design.

What low-power modes does the R5F52317AGNE#00 support, and which peripherals remain active during sleep?

The R5F52317AGNE#00 supports three low-power modes: sleep, deep sleep, and software standby. In software standby, the low-power timer (LPT) and RTC continue operating using the 32.768 kHz sub-clock or IWDT oscillator. The ELC can trigger peripheral actions (e.g., ADC conversion) without waking the CPU - enabling µA-level system power in battery-backed applications using the R5F52317AGNE#00.

How many analog-to-digital converter (ADC) channels does the R5F52317AGNE#00 provide, and what is its conversion speed?

The R5F52317AGNE#00 includes a 12-bit successive-approximation ADC with 24 input channels. At maximum ADCLK = 54 MHz, it achieves a minimum conversion time of 0.83 µs per channel. Sampling time is configurable per channel, and conversion triggers may originate from software, timers (MTU/TPU), external pins, or the ELC - ensuring precise timing control in the R5F52317AGNE#00's signal acquisition pipeline.

Is the R5F52317AGNE#00 compatible with Renesas' TSIP-Lite security features, and what cryptographic algorithms does it support?

Yes, the R5F52317AGNE#00 integrates TSIP-Lite - Renesas' trusted secure IP engine. It supports AES-128 and AES-256 in ECB, CBC, GCM, and CTR modes; CMAC and XTS for authentication; SHA-256 hashing; and a true random number generator. Keys are protected against physical and side-channel attacks, and unauthorized access to the engine is disabled - providing foundational security for firmware updates and data confidentiality in the R5F52317AGNE#00.
