Product details
Overview
HD6473297FJ16 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 types (16-bit free-running, dual 8-bit, watchdog), 10-bit A/D converter, serial communication interface (UART/SIO), and 56 I/O pins - deployed in industrial motor control and factory automation systems.
For engineers reviewing the HD6473297FJ16 datasheet, HD6473297FJ16 pinout, HD6473297FJ16 application, or HD6473297FJ16 equivalent, key selection criteria include ROM/RAM size, integrated A/D resolution, timer architecture, serial interface mode support, and single-chip mode operation without external bus expansion.
Technical Context
The HD6473297FJ16 implements the H8/300 CPU core with 24-bit address space, supporting single-chip mode (Mode 3) via SYSCR configuration and enabling direct access to on-chip ROM/RAM without wait states when operating at ≤16 MHz. Its memory map includes dedicated register fields for peripheral control, with SYSCR and MDCR governing operating mode selection and system initialization.
Peripheral integration follows a unified register-mapped I/O architecture: timers use dedicated control/status registers (e.g., TCSR, OCRx, ICRx), the A/D converter employs ADDRA–ADDRD data registers and ADCSR/ADCR for conversion control, and the serial interface supports both asynchronous UART and synchronous SIO modes via SMR/SCR/BRR configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3297FJ16 | Flash-based variant with same pinout and peripheral set; supports in-system programming | Used where firmware updates in field are required; not suitable for cost-sensitive high-volume mask-ROM deployments | Select HD64F3297FJ16 only if reprogrammability outweighs higher unit cost and reduced ROM density |
| HD6473294FJ16 | Lower-spec variant: 32 KB ROM, 1 KB RAM, same CPU/peripherals but reduced memory capacity | Applicable in simpler control tasks with smaller code footprint and fewer runtime variables | Choose HD6473294FJ16 when application fits within 32 KB ROM and does not require full 2 KB RAM buffer space |

FAQ
What is the maximum operating frequency of the HD6473297FJ16?
The HD6473297FJ16 operates at up to 16 MHz system clock frequency when using an external crystal connected to XIN/XOUT. Its internal clock generator supports direct drive from 1–16 MHz crystals, and wait-state control allows zero-wait access to on-chip ROM/RAM at this frequency. The HD6473297FJ16 does not support PLL-based frequency multiplication beyond the crystal input rate.
Does the HD6473297FJ16 support in-system programming (ISP)?
No, the HD6473297FJ16 uses mask-ROM for program storage and cannot be reprogrammed after fabrication. Firmware is permanently embedded during manufacturing. For ISP capability, engineers should consider the flash-based HD64F3297FJ16, which shares the same pinout and peripheral set but replaces mask-ROM with rewritable flash memory.
How many analog input channels does the HD6473297FJ16 A/D converter support?
The HD6473297FJ16 integrates a 10-bit successive-approximation A/D converter with 8 analog input channels (AD0–AD7), all mapped to Port 3 pins P30–P37. It supports both single-conversion and continuous scan modes, with conversion time of 16 µs per channel under typical conditions using the internal clock source.
Can the HD6473297FJ16 operate in low-power modes?
Yes, the HD6473297FJ16 supports software-controlled power-down states via the STOP instruction and system control registers. In power-down mode, the CPU halts while selected peripherals (e.g., watchdog timer, serial interface) remain active. Wake-up is triggered by external interrupts or watchdog timeout, enabling energy-efficient operation in battery-backed or standby applications.
Is the HD6473297FJ16 pin-compatible with other H8/3297 Series devices?
Yes, all H8/3297 Series variants including HD6473297FJ16, HD6473294FJ16, and HD64F3297FJ16 share identical 80-pin PQFP packaging and pin assignments. This allows hardware design reuse across memory variants and technology nodes (mask-ROM vs. flash), provided firmware accommodates differences in ROM size and boot behavior.
