Overview

HD64F7017FI28V from Renesas Electronics is a 32-bit RISC microcontroller in the SuperH™ SH7017F 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 timer/pulse unit (MTU), DMA controller, and interrupt controller. It targets real-time embedded control in industrial instrumentation and motor drive systems.

For engineers reviewing the HD64F7017FI28V datasheet, HD64F7017FI28V pinout, HD64F7017FI28V application, or HD64F7017FI28V equivalent, key selection considerations include its F-ZTAT™ flash memory architecture, 112-pin FP package with multiplexed address/data bus, external memory interface timing, and support for cycle-steal DMA transfers with DACK handshake.

Technical Context

The HD64F7017FI28V implements the SH-1 core architecture with single-cycle instruction execution for most operations and a 32-bit internal bus. Its on-chip 1 kB cache improves performance during external memory access, while the bus state controller supports DRAM, SRAM, and peripheral device interfacing via CS0–CS3 chip selects.

Peripheral integration includes two independent serial communication interfaces (SCI) supporting asynchronous and clock-synchronous modes, an 8-channel 10-bit A/D converter with sample-and-hold, and a multifunction timer/pulse unit capable of PWM generation, input capture, and phase counting - all synchronized to a common clock domain with programmable prescalers.

FAQ

What is the operating temperature range specified for the HD64F7017FI28V?

The HD64F7017FI28V is rated for an extended industrial temperature range of −40°C to +85°C, validated per Renesas Electronics' Standard quality grade specifications. This range supports deployment in unventilated control cabinets, outdoor enclosures, and environments with significant thermal cycling - unlike the standard-grade HD64F7017F28 variant, which is limited to −20°C to +75°C. The HD64F7017FI28V maintains full electrical performance across this range without derating.

Does the HD64F7017FI28V include on-chip flash memory, and what is its capacity?

Yes, the HD64F7017FI28V integrates on-chip F-ZTAT™ flash memory, enabling in-system programming and field firmware updates without external hardware programmers. While the exact flash capacity is not explicitly stated in the provided hardware manual, Renesas documentation confirms the "F" suffix denotes flash-based variants within the SH7017F family, and functional equivalence with mask-ROM versions confirms full program storage capability. The HD64F7017FI28V uses this flash for boot code and application firmware storage.

How many A/D converter channels does the HD64F7017FI28V support, and what is their resolution?

The HD64F7017FI28V supports eight analog input channels (AN0–AN7) connected to a single 10-bit successive-approximation A/D converter with built-in sample-and-hold circuitry. Each channel can be individually selected for conversion, and the converter supports both software-triggered and timer-triggered sampling modes. This resolution meets IEC 62053 Class 1 accuracy requirements for energy metering and provides sufficient dynamic range for motor current sensing and temperature monitoring in industrial control applications.

Can the HD64F7017FI28V generate multi-phase PWM signals, and how is synchronization achieved?

Yes, the HD64F7017FI28V's multifunction timer/pulse unit (MTU) supports up to seven-phase PWM output by configuring channels 0–2 in PWM mode 2 and synchronizing them using the TGR0A register as a common clear source. This synchronization ensures precise phase alignment between output waveforms - critical for driving multi-phase inverters in BLDC motor control. The MTU's TIOC pins (e.g., TIOC0A–TIOC2B) serve as dedicated PWM output terminals with programmable duty cycles and dead-time insertion capability.

What external memory interface capabilities does the HD64F7017FI28V provide?

The HD64F7017FI28V provides a 16-bit multiplexed address/data bus (A0–A17, D0–D15) with four independent chip select outputs (CS0–CS3), each configurable for different bus widths (8/16-bit), wait states, and address ranges. It supports DRAM, SRAM, and peripheral device interfacing through dedicated control signals including RD, WRH/WRL, RAS/CAS, and DACK/DREQ for DMA handshaking. The bus state controller manages timing parameters to accommodate diverse memory access profiles without CPU overhead.
