Renesas HD64F7017F28V

Overview

HD64F7017F28V from Renesas Electronics is a 32-bit RISC microcontroller in the SuperH™ SH7017 family, featuring a 28 MHz CPU clock, 1 kB on-chip cache, 3 kB RAM, and integrated peripherals including dual SCI, 8-channel 10-bit A/D converter, multifunction timers with PWM/phase counting modes, and DMA controller. It targets real-time industrial control systems requiring deterministic response and external memory interfacing.

For engineers reviewing the HD64F7017F28V datasheet, HD64F7017F28V pinout, HD64F7017F28V application, or HD64F7017F28V equivalent, key selection criteria include its F-ZTAT™ flash-based architecture, 112-pin FP package with multiplexed address/data bus, DRAM control support, and compatibility with SH-1 instruction set for legacy code reuse.

Technical Context

The HD64F7017F28V implements the SH-1 core with single-cycle RISC execution and 32-bit internal bus architecture, enabling high throughput in real-time embedded applications. It integrates a direct memory access controller supporting cycle-steal and burst modes, an interrupt controller with programmable priority registers (IPRA–IPRH), and a bus state controller managing CS0/CS1 chip selects and DRAM timing via DCR register.

Peripheral integration includes two serial communication interfaces (SCI) with full-duplex asynchronous operation, a 10-bit A/D converter with 8 input channels and sample-and-hold, and a multifunction timer unit (MTU) offering four independent channels with input capture, output compare, PWM mode 1/2, and phase counting modes 1–4 - all synchronized to internal clock or external sources.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the HD64F7017F28V?

The HD64F7017F28V operates at a maximum CPU clock frequency of 28 MHz, derived from an external crystal (EXTAL/XTAL) multiplied by the on-chip PLL. This frequency is guaranteed across the commercial temperature range (0°C to +70°C) and defines the upper limit for instruction execution speed, peripheral timing, and bus cycle rates in external memory interfaces.

Does the HD64F7017F28V include on-chip flash memory?

Yes, the HD64F7017F28V features F-ZTAT™ on-chip flash memory, enabling in-system programming and field firmware updates. This eliminates the need for external EPROM sockets or UV erasers and supports secure bootloader implementations - a key differentiator from the ROMless HD64F7014F28V and mask-ROM HD64F7016F28V variants in the same family.

How many A/D input channels does the HD64F7017F28V support?

The HD64F7017F28V integrates an 8-channel, 10-bit successive-approximation A/D converter with sample-and-hold circuitry. Inputs map directly to PF0–PF7 pins, supporting simultaneous sampling control and conversion completion interrupts - essential for synchronized multi-sensor acquisition in closed-loop control systems using the HD64F7017F28V.

What package type is used for the HD64F7017F28V?

The HD64F7017F28V is housed in a 112-pin Fine Pitch (FP) plastic QFP package with 0.5 mm lead pitch. This package provides full access to the multiplexed 22-bit address bus (A0–A21), 16-bit data bus (D0–D15), and all peripheral I/O ports (PA, PB, PE, PF), while meeting industrial thermal dissipation requirements under continuous 28 MHz operation.

Is the HD64F7017F28V pin-compatible with other SH7017 variants?

Yes, the HD64F7017F28V shares identical pinout and electrical characteristics with other SH7017 family members including HD64F7017F32V and HD64F7017F20V. Differences are limited to maximum clock rating and internal flash configuration - allowing drop-in replacement across speed grades without PCB redesign, provided system timing constraints are verified for the target frequency.
