Product details
Overview
HD64F3672FYIV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 64 KB on-chip ROM, 4 KB RAM, and integrated peripherals including UART, timer/counters, and I/O ports. It operates at up to 20 MHz and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the HD64F3672FYIV datasheet, HD64F3672FYIV pinout, HD64F3672FYIV application, or HD64F3672FYIV equivalent, key selection considerations include its 80-pin QFP package, flash memory programmability, low-power sleep/standby modes, and support for on-board programming via single power supply.
Technical Context
The HD64F3672FYIV implements the H8/300H CPU architecture with 24-bit addressing, supporting both byte and word data access. Its memory map includes 64 KB of on-chip ROM (flash), 4 KB of RAM, and dedicated register areas for peripheral control - all accessible without external bus expansion.
It integrates system-level functions including a programmable clock generator with crystal/ceramic resonator support, three 16-bit timer/counters (one with input capture/output compare), two asynchronous serial interfaces (UART), and 64 general-purpose I/O pins configurable as inputs, outputs, or peripheral function pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300, enabling legacy code reuse and toolchain continuity. |
| ROM Capacity | 64 KB on-chip flash memory, supporting in-system programming and erase-verify cycles for field firmware updates. |
| RAM Size | 4 KB on-chip SRAM, sufficient for real-time stack, variables, and interrupt service routine context storage. |
| Max Operating Frequency | 20 MHz system clock, achievable using external crystal (up to 20 MHz) or ceramic resonator with internal PLL prescaling. |
| I/O Pins | 64 programmable bidirectional I/O pins across Ports A–H, with individual direction and pull-up control per pin. |
| Peripherals | Two UART channels, three 16-bit timers (including one with input capture), watchdog timer, and on-chip voltage regulator for internal logic. |
| Power Modes | Three low-power states: Sleep (CPU halted, peripherals active), Standby (CPU/peripherals halted, RAM retained), Subsleep (deep retention with wake-on-interrupt). |
Pinout & Package
HD64F3672FYIV is housed in an 80-pin plastic quad flat package (QFP) with 0.65 mm lead pitch, compliant with JEDEC MS-026 standard. The package supports surface-mount reflow assembly and provides full signal access to all on-chip resources.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs for analog/digital separation; decoupling required within 10 mm for stable 5 V operation. |
| XTAL1/XTAL2 | Crystal oscillator input/output | Connects to 4–20 MHz crystal or ceramic resonator; internal feedback resistor enables self-oscillation without external components. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers and initializes I/O port states; internal pull-up ensures defined startup behavior. |
| INT0–INT7 | External interrupt inputs | Edge-selectable (rising/falling) inputs mapped to priority-controlled interrupt vectors; support wake-from-standby functionality. |
| TXD0/RXD0 | UART0 transmit/receive | Full-duplex asynchronous serial interface compatible with RS-232/RS-485 level shifters; baud rate programmable via timer-derived clock. |
| PORTA0–PORTA7 | General-purpose I/O port A | 8-bit bi-directional port with individually controllable direction bits and weak pull-up resistors; usable as data bus in expanded mode. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash Memory | 64 KB reprogrammable flash with hardware/software write protection and sector erase capability for secure firmware updates. |
| Single-Supply On-Board Programming | Supports flash programming and erasure using only the main 5 V supply - no high-voltage VPP required - simplifying production and field service. |
| Low-Power Operation | Subsleep mode draws ≤10 µA at 5 V; wake-up latency <10 µs from standby, enabling battery-powered sensor node designs. |
| Integrated Clock Generation | Configurable system clock source selection (crystal, ceramic, or external clock) with programmable prescalers for flexible timing tree design. |
| Hardware Watchdog Timer | Dedicated independent watchdog with windowed timeout detection and reset output, enhancing system reliability in unattended operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3687FV | Same H8/3672 family but with 128 KB flash, 8 KB RAM, and additional CAN controller; 100-pin LQFP package. | Targeted at more complex systems requiring CAN bus connectivity and larger firmware footprint. | Select HD64F3687FV when CAN protocol support and >64 KB code space are mandatory; not pin-compatible with HD64F3672FYIV. |
| HD64F3664FV | Lower-density variant: 32 KB flash, 2 KB RAM, same 80-pin QFP; lacks UART1 and one timer channel. | Suitable for cost-sensitive, functionally minimal control tasks where dual UART or extra timer is unnecessary. | Choose HD64F3664FV for simplified BOMs and reduced PCB layer count; shares identical pinout and footprint with HD64F3672FYIV. |
Compared with HD64F3672FYIV, HD64F3664FV offers identical packaging and mechanical compatibility but reduced memory and peripheral count, while HD64F3687FV delivers higher integration at the cost of package and layout redesign.

FAQ
What is the maximum operating frequency of the HD64F3672FYIV?
The HD64F3672FYIV supports a maximum system clock frequency of 20 MHz. This is achieved using an external crystal or ceramic resonator connected to XTAL1/XTAL2, or via external clock input. The internal clock generator includes prescalers that allow flexible division of the base oscillator frequency to meet specific timing requirements across different peripherals.
Does the HD64F3672FYIV support in-system programming of its flash memory?
Yes, the HD64F3672FYIV supports in-system programming (ISP) of its 64 KB on-chip flash memory using only the standard 5 V supply - no external VPP voltage is required. Programming and erasure can be performed in user program mode or boot mode, with hardware and software protection mechanisms preventing accidental writes.
What power-saving modes does the HD64F3672FYIV offer?
The HD64F3672FYIV provides three low-power modes: Sleep (CPU halted, peripherals active), Standby (CPU and peripherals halted, RAM retained), and Subsleep (deep retention with wake-on-interrupt). Subsleep mode draws less than 10 µA at 5 V, making it suitable for battery-backed applications requiring extended idle periods.
Is the HD64F3672FYIV pin-compatible with other devices in the H8/3672 group?
Yes, the HD64F3672FYIV shares the same 80-pin QFP package and pin assignment with the HD64F3664FV, enabling direct substitution in designs where reduced memory and peripheral count are acceptable. However, it is not pin-compatible with higher-pin-count variants like the HD64F3687FV (100-pin LQFP).
What development tools are supported for the HD64F3672FYIV?
The HD64F3672FYIV is supported by Renesas' High-Performance Embedded Workshop (HEW) IDE, E8 in-circuit emulator, and the H8/300H Series C/C++ Compiler. Debugging via the on-chip emulator uses dedicated pins (NMI reserved, address ranges H'4000–H'4FFF and H'F780–H'FB7F restricted), and requires adherence to hardware setup guidelines in the Hardware Manual Rev.4.00.
