Overview
R5F72147HDFP#V1 from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring 512 KB on-chip Flash memory, 64 KB RAM, and integrated peripherals including SCI, I²C, CAN 2.0B controller, MTU2S timer, and 10-bit ADC. It operates at up to 64 MHz and targets industrial control and motor drive applications requiring deterministic real-time response.
For engineers reviewing the R5F72147HDFP#V1 datasheet, R5F72147HDFP#V1 pinout, R5F72147HDFP#V1 application, or R5F72147HDFP#V1 equivalent, key selection criteria include CAN interface support, Flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with Renesas' HEW and e2 studio development tools.
Technical Context
The R5F72147HDFP#V1 implements the SH-2A CPU core with FPU support, executing instructions in a five-stage pipeline with branch prediction. It integrates a Clock Pulse Generator (CPG) supporting multiple clock sources-including crystal resonator, external clock, and internal PLL-with programmable frequency division for system, peripheral, and USB clocks.
Its interrupt architecture includes an Interrupt Controller (INTC) with 128 vector entries and priority levels (0–15), enabling fast context switching. The on-chip CAN controller complies with ISO 11898-1:2003 and supports both standard and extended frames, mailbox-based transmission/reception, and error confinement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | SH-2A 32-bit RISC with FPU, 64 MHz max operation - enables floating-point math for motor control algorithms without software emulation. |
| Memory | 512 KB Flash (10K erase/write cycles), 64 KB RAM - sufficient for field-upgradable firmware and real-time data buffering. |
| CAN Interface | One CAN 2.0B controller with 32 message buffers - supports multi-node industrial networks with prioritized message arbitration. |
| ADC | 10-bit SAR ADC, 16 channels, 1.25 µs conversion time - suitable for analog sensor acquisition in closed-loop motor control. |
