Product details
Overview
HD64F3687GHV 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 applications in industrial equipment and consumer electronics.
For engineers reviewing the HD64F3687GHV datasheet, HD64F3687GHV pinout, HD64F3687GHV application, or HD64F3687GHV equivalent, key selection criteria include its 100-pin PQFP package, 5 V operation, ROM-based program storage, low-power sleep/standby modes, and peripheral integration for cost-sensitive real-time control systems.
Technical Context
The HD64F3687GHV implements the H8/300H CPU architecture with 24-bit addressing, supporting both byte- and word-aligned memory access. Its system clock generator accepts crystal (1–20 MHz), ceramic resonator, or external clock input, and includes independent subclock circuitry for 32.768 kHz RTC support.
Power management includes four low-power modes-Sleep, Standby, Subsleep, and Subactive-with configurable module-level standby via MSTCR1/MSTCR2 registers. Interrupt handling supports 63 sources with prioritized vectoring, edge-selectable external interrupts, and wakeup capability from all power-down states.
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. |
| ROM Capacity | 64 KB on-chip mask ROM, fixed program storage eliminating external memory footprint. |
| RAM Size | 4 KB on-chip RAM, sufficient for stack, variables, and small real-time data buffers. |
| Max Clock Frequency | 20 MHz system clock, delivering ~10 MIPS performance for deterministic control loops. |
| Supply Voltage | 4.5 V to 5.5 V operation, compatible with standard 5 V logic and industrial power rails. |
| I/O Pins | 80 general-purpose CMOS I/O pins with programmable pull-up resistors and interrupt-capable inputs. |

Pinout & Package
HD64F3687GHV is housed in a 100-pin plastic quad flat pack (PQFP) with 0.5 mm lead pitch, designed for surface-mount assembly and thermal dissipation in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| XTAL1/XTAL2 | Crystal oscillator input/output | Supports fundamental-mode quartz crystals (1–20 MHz) for precise system timing. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state and initializes peripherals on power-up or fault recovery. |
| INT0–INT7 | External interrupt inputs | Edge-selectable (rising/falling) inputs mapped to priority levels for responsive event handling. |
| P00–P97 | Programmable I/O ports | 80 bidirectional CMOS ports with latch, direction, and pull-up control registers per port group. |
Key Features
| Feature | Design Value |
|---|---|
| H8/300H CPU Compatibility | Enables migration from H8/300 designs without instruction set rework or toolchain changes. |
| Integrated ROM + RAM | Eliminates need for external program memory, reducing BOM count and PCB area in cost-sensitive controllers. |
| Four Power-Down Modes | Subactive mode maintains RTC and serial communication while cutting CPU power, extending battery life in portable devices. |
| On-Chip Debug Support | Hardware debug interface compatible with E7/E8 emulators enables non-intrusive breakpoint and trace without dedicated debug pins. |
| Peripheral Module Standby | Independent enable/disable of UART, timers, and ADC via MSTCR registers reduces dynamic power during idle intervals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3687G | Same die, identical pinout and electrical specs; differs only in marking (no 'HV' suffix) and minor packaging variant. | No functional difference; suitable for same PCB layouts and firmware binaries. | Select HD64F3687G if HV-grade qualification is not required and standard industrial temperature range suffices. |
| HD64F3684G | Lower memory configuration: 32 KB ROM, 2 KB RAM; otherwise identical peripheral set and pinout. | Targeted at simpler control tasks with smaller firmware footprints and reduced RAM usage. | Choose HD64F3684G when application code size stays under 32 KB and memory headroom is acceptable. |
Compared with HD64F3687GHV, HD64F3687G offers identical functionality without HV-grade screening, while HD64F3684G provides a memory-scaled alternative for less complex firmware-both retain full software and hardware compatibility within the H8/3687 family.

FAQ
What is the operating temperature range for HD64F3687GHV?
The HD64F3687GHV is rated for industrial temperature operation from −40°C to +85°C. This range supports deployment in factory automation panels, outdoor kiosks, and HVAC equipment without additional thermal mitigation. The 'HV' suffix indicates enhanced screening for high-reliability applications within this grade, consistent with Renesas' Standard quality classification per their documentation.
Does HD64F3687GHV include on-chip debug capability?
Yes, HD64F3687GHV supports on-chip debugging via the on-chip emulator interface compatible with Renesas E7 and E8 debug tools. It uses dedicated pins (NMI, P85–P87) in debug mode, with address break and watchpoint features enabled through ABRKCR and related registers-no external JTAG adapter is needed for basic firmware development and validation of HD64F3687GHV.
Is HD64F3687GHV pin-compatible with other H8/3687 family members?
Yes, HD64F3687GHV shares the same 100-pin PQFP package and pin assignment with HD64F3687G, HD64F3684G, and HD64N3687G. All share identical power, clock, reset, and I/O pin locations, enabling drop-in replacement across memory variants-provided firmware and PCB layout accommodate the specific ROM/RAM configuration of each part.
What clock sources does HD64F3687GHV support?
HD64F3687GHV supports three clock source configurations: fundamental-mode quartz crystal (1–20 MHz) between XTAL1/XTAL2, ceramic resonator with built-in capacitors, or external CMOS-level clock signal applied to XTAL1. A separate 32.768 kHz subclock circuit supports RTC functions independently of main system timing.
Can HD64F3687GHV operate from a 3.3 V supply?
No, HD64F3687GHV requires a 4.5 V to 5.5 V supply and is not rated for 3.3 V operation. Its I/O structure, internal voltage regulators, and flash programming thresholds are designed exclusively for 5 V logic families. Using 3.3 V will result in undefined behavior, failed resets, or inability to execute instructions reliably on HD64F3687GHV.
