Product details
Overview
HD6473297FE16 from Hitachi is a mask-ROM-based 16-bit microcontroller in the H8/3297 Series, featuring an H8/300 CPU core, 60 KB on-chip ROM, 2 KB RAM, three timer modules (16-bit free-running + two 8-bit), 10-bit A/D converter with 8 input channels, and asynchronous/synchronous serial interface. It operates at up to 20 MHz and targets embedded motor control and industrial I/O systems.
For engineers reviewing the HD6473297FE16 datasheet, HD6473297FE16 pinout, HD6473297FE16 application, or HD6473297FE16 equivalent, key selection criteria include ROM size, integrated A/D resolution, timer architecture, serial protocol support, and single-chip mode operation without external bus expansion.
Technical Context
The HD6473297FE16 implements the H8/300 CPU core with 16-bit data bus and 24-bit address space, supporting 15 addressing modes and 128 instructions. Its memory map includes fixed ROM/RAM regions, peripheral register fields, and configurable wait-state control for external access.
Hardware peripherals are memory-mapped: the 16-bit free-running timer supports input capture and output compare with four capture registers; dual 8-bit timers provide PWM and interval timing; the A/D converter uses software- or external-triggered conversion with per-channel result registers ADDRA–ADDRD.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3297FV | ZTAT™ version with flash-based 60 KB program memory - supports field firmware updates | Preferred for prototyping or products requiring post-deployment code revisions | Select HD64F3297FV when firmware flexibility outweighs cost and security constraints of mask-ROM |
| HD6433297 | Same core and peripheral set but 48 KB ROM and 2 KB RAM - lower-cost variant with reduced code space | Suitable for simpler control tasks where full 60 KB is unused, e.g., basic timer-based sequencers | Choose HD6433297 if application binary fits within 48 KB and BOM cost reduction is critical |
Compared with HD6473297FE16, HD64F3297FV trades mask-ROM permanence for field-programmability, while HD6433297 reduces ROM capacity without altering peripheral functionality - both retain identical pinout, clock architecture, and A/D/timer specifications.

FAQ
What is the maximum operating frequency of the HD6473297FE16?
The HD6473297FE16 supports a maximum system clock frequency of 20 MHz, derived from an external crystal (XIN/XOUT) or clock source. This frequency governs CPU instruction execution, A/D conversion timing, and timer overflow rates. The device's internal wait-state controller ensures reliable access to on-chip ROM and RAM at this speed without external glue logic.
Does the HD6473297FE16 support in-circuit programming or firmware updates?
No, the HD6473297FE16 uses mask-ROM for program storage, which is permanently programmed during fabrication and cannot be modified in the field. For reprogrammable alternatives, consider the HD64F3297FV - a ZTAT™ flash-based variant of the same H8/3297 family that supports in-system programming via on-chip bootloader.
How many analog input channels does the HD6473297FE16 A/D converter support?
The HD6473297FE16 integrates a 10-bit successive-approximation A/D converter with 8 multiplexed input channels (AD0–AD7), mapped to port P20–P27. These pins default to analog input after reset and can be configured individually for single-shot or scan-mode conversions triggered by software or external signal on P47.
What package type is used for the HD6473297FE16?
The HD6473297FE16 is supplied in a 100-pin plastic quad flat package (QFP) with 0.65 mm lead pitch, designated FP-100 by Hitachi. This package supports surface-mount assembly and provides full access to all I/O ports, timer, serial, and A/D interface signals without requiring ball-grid array or exposed-pad thermal enhancements.
Can the HD6473297FE16 operate without external memory or bus interface?
Yes, the HD6473297FE16 is designed for single-chip mode operation: all 60 KB ROM, 2 KB RAM, and peripherals are integrated on-die. No external address/data bus, memory chips, or bus controllers are needed - enabling compact, low-noise PCB layouts ideal for space-constrained industrial modules.
