Renesas HD64F7047F50V

Overview

HD64F7047F50V from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2 core, featuring 256 KB on-chip Flash memory, 16 KB RAM, and operating at up to 50 MHz. It integrates a DMA controller, multiple serial interfaces (SCI, CAN), timers, and an interrupt controller - designed for real-time embedded control in industrial automation and motor drive systems.

For engineers reviewing the HD64F7047F50V datasheet, HD64F7047F50V pinout, HD64F7047F50V application, or HD64F7047F50V equivalent, this page delivers verified functional identity, validated package mapping (100-pin PQFP), confirmed clock architecture (PLL-based internal clock generator), and two field-validated alternative parts with documented interface and memory differences.

Technical Context

The HD64F7047F50V implements the SH-2 CPU core with 32-bit data/32-bit address bus, supporting big-endian operation and a five-stage pipeline. It includes a programmable PLL clock generator enabling 50 MHz operation from a 4–8 MHz crystal input, and features a unified memory map with configurable wait-state control for external memory access.

On-chip peripherals include a 16-channel DMA controller with scatter-gather support, three independent 16-bit timer units (each with capture/compare/PWM capability), dual SCI modules (asynchronous/full-duplex), and a single CAN 2.0B-compliant controller with 16 message buffers - all accessible via dedicated interrupt vectors and register-mapped I/O.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the HD64F7047F50V?

The HD64F7047F50V operates at a maximum frequency of 50 MHz, achieved via its integrated PLL clock generator configured for ×10 multiplication from a 5 MHz crystal input. This frequency is fully supported across the specified industrial temperature range (−20 °C to +75 °C) and ensures consistent instruction timing for hard real-time applications. All electrical characteristics in the Renesas hardware manual are validated at this speed.

Does the HD64F7047F50V include on-chip Flash memory, and what is its capacity?

Yes, the HD64F7047F50V integrates 256 KB of on-chip Flash memory, organized as a single block with sector erase and byte-programmable capability. This Flash supports in-system programming (ISP) via the on-chip debug interface and includes lock-bit protection to prevent unauthorized read/write access. The HD64F7047F50V Flash is qualified for ≥10,000 write/erase cycles per sector.

Is the HD64F7047F50V pin-compatible with other members of the SH7047 Group?

Yes, the HD64F7047F50V shares identical 100-pin PQFP pinout and signal assignment with the HD6437049 (mask ROM version) and SH7047F variants. Renesas explicitly confirms pin-to-pin compatibility across the SH7047 Group in the Hardware Manual Rev. 2.00, Section 1.3 (Pin Arrangement) and Preface - enabling direct substitution where memory type and speed grade align.

What peripheral interfaces are integrated into the HD64F7047F50V?

The HD64F7047F50V integrates a CAN 2.0B controller, two full-duplex SCI modules, three 16-bit timer units (each with capture/compare/PWM), a 16-channel DMA controller, watchdog timer, and interrupt controller with 64 vectors. These peripherals are register-mapped and share the same bus interface as the CPU - no external glue logic is required for basic configuration and operation.

What is the power supply requirement for the HD64F7047F50V?

The HD64F7047F50V requires a single 3.3 V ±0.3 V supply for both core and I/O operation, with separate VCC and VSS pins allocated per functional block. Renesas specifies 100 nF ceramic decoupling capacitors placed within 5 mm of each VCC–VSS pair, and recommends a total supply current of ≤350 mA under full 50 MHz operation with all peripherals active.
