Product details
Overview
HD64F7145F50V from Renesas Electronics is a 32-bit RISC microcontroller in the SH7145 Group, featuring a SuperH™ CPU core, 256 KB on-chip Flash memory, 144-pin LQFP package, and operation up to 50 MHz - designed for embedded control in industrial automation and motor drive systems.
For engineers reviewing the HD64F7145F50V datasheet, HD64F7145F50V pinout, HD64F7145F50V application, or HD64F7145F50V equivalent, key selection criteria include its 50 MHz max clock frequency, integrated 10-bit ADC with 16 channels, dual CAN 2.0B controllers, and support for single-chip mode with external bus interface capability.
Technical Context
The HD64F7145F50V implements the SH-2 instruction set architecture with 32-bit data/32-bit address bus, supports both little-endian and big-endian modes, and integrates a programmable interrupt controller with 128 vector entries. Its on-chip peripherals include two 32-bit timer units (MTU), a serial communication interface (SCI) with UART/IrDA support, and a watchdog timer with independent clock source.
It features a 4-stage pipeline execution unit, 16 KB on-chip RAM, and memory protection unit (MPU) with 8 regions - enabling real-time deterministic response in safety-critical industrial firmware. The device operates from a single 3.3 V supply and supports low-power standby and sleep modes with wake-up via external interrupt or internal timer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | SH-2 32-bit RISC core with 4-stage pipeline and 32×32-bit integer ALU - enables deterministic real-time instruction execution at 50 MHz. |
| Max Clock Frequency | 50 MHz - defines maximum instruction throughput of ~50 MIPS and timing resolution for PWM and capture functions. |
| On-Chip Memory | 256 KB Flash (programmable in-system), 16 KB SRAM - supports field firmware updates without external programming hardware. |
| Analog Peripherals | 10-bit ADC with 16 input channels and 1.2 μs conversion time - suitable for closed-loop motor current/voltage sensing. |
| Communication Interfaces | Dual CAN 2.0B controllers + 3x SCI (UART/IrDA) + I²C - enables robust multi-node industrial network integration. |
| Package & Pin Count | 144-pin LQFP (20 × 20 mm, 0.5 mm pitch) - provides full external bus interface (address/data multiplexed) and dedicated peripheral pins. |
| Supply Voltage | 3.3 V ±0.3 V - requires single-rail power design with decoupling per power domain (core/I/O/ADC). |
Pinout & Package
HD64F7145F50V is housed in a 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows SH7145 Group standard layout, supporting single-chip and expanded bus modes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pins per power domain (core, I/O, ADC) - require separate decoupling and PCB plane partitioning. |
| CLK, EXTAL, XTAL | External clock input | Supports crystal (1–20 MHz) or external clock source - used to generate internal 50 MHz PLL output. |
| RESET | Active-low reset input | Asynchronous, level-sensitive reset - must be held low ≥1024 cycles after power stabilization before release. |
| AD0–AD15 | Address/data multiplexed bus | 16-bit bidirectional bus for external memory/peripheral expansion in expanded mode - requires external latch control. |
| INTA–INTL | Interrupt request inputs | 12 dedicated edge-triggered interrupt pins - support prioritized nested interrupt handling with vector table lookup. |
| TXA0/RXA0, TXA1/RXA1 | SCI channel 0/1 serial I/O | Full-duplex UART with programmable baud rate generator - supports RS-232/RS-485 interface with external transceivers. |
| CAN0TX/CAN0RX, CAN1TX/CAN1RX | CAN controller I/O | Dual independent CAN 2.0B physical layer interfaces - require external CAN transceivers (e.g., TJA1050) for bus connection. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CAN 2.0B Controllers | Dual independent CAN modules with message buffers and error counters - enable distributed control networks without external protocol ICs. |
| On-Chip Flash Memory (256 KB) | Single-power-supply reprogrammable Flash with sector erase and 100K-cycle endurance - eliminates need for external EEPROM or boot ROM. |
| 10-Bit 16-Channel ADC | Simultaneous sampling not supported, but configurable trigger sources (timer, external event) - allows synchronized analog acquisition across motor phases. |
| Memory Protection Unit (MPU) | 8-region MPU with read/write/execute permissions per region - enforces firmware partitioning and prevents accidental code overwrite or stack overflow corruption. |
| Low-Power Operating Modes | Four modes: Sleep, Standby, Wait, and Stop - reduce current to ≤50 μA in Stop mode while retaining RAM content and wake-up capability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F7145F40V | Same SH7145 architecture and pinout, but rated for 40 MHz max clock - lower performance, reduced power consumption. | Suitable for cost-sensitive applications where 50 MHz timing margin is unnecessary (e.g., basic HVAC sequencers). | Select HD64F7145F40V only when system timing budget permits 20% lower instruction throughput and lower thermal dissipation is critical. |
| R5F57145ADFP | RX71M series successor: 32-bit RXv2 core, 120 MHz, 512 KB Flash, enhanced CAN FD support - not pin-compatible. | Enables migration path to higher performance, functional safety (IEC 61508 SIL2-ready), and CAN FD for future-proofed designs. | Choose R5F57145ADFP for new designs requiring extended lifecycle, safety certification support, or bandwidth beyond CAN 2.0B. |
Compared with HD64F7145F40V, the HD64F7145F50V delivers 25% higher deterministic throughput for time-critical control loops; compared with R5F57145ADFP, it offers mature toolchain support and lower BOM cost but lacks CAN FD and functional safety features.

FAQ
What is the maximum operating frequency of the HD64F7145F50V?
The HD64F7145F50V is rated for a maximum operating frequency of 50 MHz, achieved using an internal PLL that multiplies an external crystal or clock input. This frequency determines the instruction execution rate (~50 MIPS), PWM resolution, and ADC sampling timing precision. Operation above 50 MHz is not guaranteed and violates the device's electrical specifications.
Does the HD64F7145F50V support CAN FD or only classical CAN 2.0B?
The HD64F7145F50V supports only CAN 2.0B - it includes two fully compliant CAN 2.0B controllers with message objects, error handling, and bit-rate configuration up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. For CAN FD, consider the newer RX71M series like R5F57145ADFP.
Is the HD64F7145F50V pin-compatible with other SH7145 Group variants?
Yes, the HD64F7145F50V shares identical pinout and package (144-pin LQFP) with all other SH7145 Group members including HD6437145 (masked ROM) and HD6417145 (ROM-less). Differences lie in memory configuration and factory-programmed options - not pin function or mechanical footprint - enabling drop-in replacement within the same group.
What development tools are officially supported for the HD64F7145F50V?
Renesas officially supports the HD64F7145F50V with the High-performance Embedded Workshop IDE, C/C++ Compiler for SuperH (CCS), and Simulator/Debugger for Windows. Legacy tools like the E8 emulator are compatible, and third-party GCC-based toolchains (e.g., sh-elf-gcc) are community-supported but not validated by Renesas for production use.
What is the qualified quality grade for the HD64F7145F50V according to Renesas documentation?
Per Renesas documentation, the HD64F7145F50V is classified as "Standard" grade, intended for applications including industrial robots, factory automation equipment, office machinery, and test/measurement instruments - not for automotive, medical life-support, or aerospace use without explicit written consent from Renesas Electronics.
