It targets embedded control in industrial automation and office equipment.

For engineers reviewing the HD64F7144F50V datasheet, HD64F7144F50V pinout, HD64F7144F50V application, or HD64F7144F50V equivalent, key selection criteria include Flash memory size, 112-pin LQFP package compatibility, 3.3 V operation, and support for single-chip mode with internal clock generation.

Technical Context

The HD64F7144F50V implements the SH-2 instruction set architecture with 32-bit data path, 16 general-purpose registers, and hardware multiply/divide unit. It supports four MCU operating modes - including single-chip mode - and integrates a programmable clock pulse generator with crystal oscillator input and oscillator halt detection.

Its peripheral set includes three 16-bit timer units (each with capture/compare/PWM), two asynchronous serial communication interfaces (SCI), a 10-channel DMA controller, and 80 general-purpose I/O pins. All peripherals are memory-mapped and accessible via 32-bit address space with configurable wait states.

FAQ

What is the maximum operating frequency of the HD64F7144F50V?

The HD64F7144F50V operates at a maximum frequency of 50 MHz, as confirmed by Renesas Hardware Manual Rev.4.00. This rating applies under specified 3.3 V supply and −20 °C to +75 °C ambient conditions. The device uses an internal PLL to multiply the input crystal or external clock, enabling high-speed instruction execution while maintaining timing integrity across all on-chip peripherals.

Does the HD64F7144F50V include on-chip Flash memory, and what is its capacity?

Yes, the HD64F7144F50V integrates 256 KB of on-chip Flash memory, as documented in the SH7144 Group Hardware Manual. This Flash is used for program storage and supports in-system programming, sector erase, and byte-level writes. It eliminates the need for external nonvolatile memory in most standalone embedded applications and enables field firmware updates without removing the HD64F7144F50V from the target board.

What package type and pin count does the HD64F7144F50V use?

The HD64F7144F50V is packaged in a 112-pin LQFP (Low-Profile Quad Flat Package) with 0.65 mm lead pitch and 20 mm × 20 mm body size. This package is explicitly defined in Section 1.3 (Pin Arrangement) of the Renesas SH7144 Group Hardware Manual Rev.4.00 and is shared across the SH7144F series, ensuring consistent PCB footprint and thermal characteristics for HD64F7144F50V deployments.

Which communication interfaces are integrated into the HD64F7144F50V?

The HD64F7144F50V integrates two asynchronous serial communication interfaces (SCI), each supporting full-duplex UART operation with programmable baud rates, framing error detection, and multiple clock source options. It also includes a 10-channel DMA controller to handle data transfers autonomously. No CAN, I²C, or USB controllers are included - those functions require external components or higher-pin-count variants like the HD64F7145F50V.

Is the HD64F7144F50V pin-compatible with other SH7144 Group members?

The HD64F7144F50V shares the same 112-pin LQFP package and pinout with other SH7144F-series devices such as HD64F7144F40V, making them mechanically and electrically interchangeable on the same PCB footprint. However, functional differences - including maximum clock frequency and certain peripheral timing limits - must be verified in system-level validation. Firmware remains binary-compatible across SH7144F variants due to identical SH-2 core and memory map.
