Product details
Overview
HD64F7045FI28V from Renesas Electronics is a 32-bit RISC microcontroller based on the SH-2 CPU core, featuring 256 kB on-chip flash memory, 32-bit external bus interface, and ±4 LSB A/D conversion accuracy at 28 MHz operation. It integrates timers, SCI serial interfaces, DMA controller, and 8-channel 10-bit A/D converter - deployed in industrial control panels requiring deterministic real-time response and field-upgradable firmware.
For engineers reviewing the HD64F7045FI28V datasheet, HD64F7045FI28V pinout, HD64F7045FI28V application, or HD64F7045FI28V equivalent, this page delivers verified technical context, package mapping to QFP2020-144, confirmed flash-programmable architecture, and validated alternatives for legacy SH7045-series migration paths.
Technical Context
The HD64F7045FI28V implements the SuperH RISC engine SH-2 core with single-cycle instruction execution, 1-kbyte on-chip cache, and 32-bit internal bus architecture. It supports external memory access via a 32-bit data bus and 22-bit address bus (A0–A21), enabling direct connection to DRAM and SRAM without glue logic.
Its integrated peripherals include four multifunction timer units (MTU) with PWM and capture/compare capability, two asynchronous/synchronous serial communication interfaces (SCI0/SCI1), and a 16-channel interrupt controller with priority encoding. The device operates in user mode and user program mode for flash programming, with dedicated FLMCR registers controlling erase/verify sequences.

FAQ
What is the maximum operating frequency of the HD64F7045FI28V?
The HD64F7045FI28V is rated for a maximum CPU clock frequency of 28 MHz, as specified in its electrical characteristics table under standard 5 V operation. This frequency enables 28 MIPS throughput and supports real-time tasks such as multi-axis motion control with sub-millisecond loop timing. The device does not support overclocking beyond this rated speed.
Does the HD64F7045FI28V support in-system programming of its flash memory?
Yes, the HD64F7045FI28V supports full in-system programming via software commands executed in user program mode. Its flash memory can be erased and reprogrammed using dedicated FLMCR registers and verified through built-in program/erase verify logic - eliminating the need for external programmers during field firmware updates.
What package type and pin count does the HD64F7045FI28V use?
The HD64F7045FI28V uses a 144-pin plastic quad flat package (QFP2020-144) with 0.5 mm pitch and copper leadframe, as documented in Renesas' SH7040 Series Hardware Manual Rev.6.00. This package is mechanically and electrically identical to the standard QFP2020-144 but incorporates copper for improved thermal performance.
Can the HD64F7045FI28V operate with a 3.3 V supply?
No - the HD64F7045FI28V is a 5 V-only device. Its absolute maximum ratings, DC characteristics, and recommended operating conditions specify a Vcc range of 4.5 V to 5.5 V. It is not compatible with 3.3 V logic families without level translation, and internal regulators do not support lower core voltages.
What is the A/D converter resolution and accuracy of the HD64F7045FI28V?
The HD64F7045FI28V features an 8-channel, 10-bit successive-approximation A/D converter with ±4 LSB integral nonlinearity (INL) and ±4 LSB offset error, as specified for the "Mid-Speed" variant in the SH7040 Series documentation.
