Product details
Overview
HD6473278PJ10 from Hitachi is a 16-bit single-chip microcontroller in the H8/327 series, featuring an H8/300 CPU core, 16 KB masked ROM, 512-byte RAM, 16-bit free-running timer, dual 8-bit timers, SCI serial interface, 8-channel 10-bit A/D converter, and 48 I/O pins - deployed in industrial motor control and embedded instrumentation systems.
For engineers reviewing the HD6473278PJ10 datasheet, HD6473278PJ10 pinout, HD6473278PJ10 application, or HD6473278PJ10 equivalent, key selection criteria include ROM size, A/D channel count, timer resolution, SCI compatibility, and power-down mode support for low-energy operation.
Technical Context
The HD6473278PJ10 implements the H8/300 CPU architecture with two-way general register configuration (eight 16-bit or sixteen 8-bit registers), executing ADD/SUB in 0.2 µs and MUL/DIV in 1.4 µs at up to 10 MHz. It supports three MCU operating modes: single-chip, expanded mode 1, and expanded mode 2 - selected via external pins and controlled by SYSCR (H'FFC4) and MDCR (H'FFC5).
On-chip peripherals include a 16-bit free-running timer with input capture (ICRA–ICRD), output compare (OCRA/OCRB), and overflow interrupt; two independent 8-bit timers (TMR0/TMR1); full-duplex asynchronous/clocked synchronous SCI; and an 8-input, 10-bit successive-approximation A/D converter with scan/single conversion modes and external trigger capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the maximum operating frequency of the HD6473278PJ10?
The HD6473278PJ10 operates at a maximum system clock frequency of 10 MHz. This clock rate governs instruction execution speed (e.g., ADD/SUB in 0.2 µs), A/D conversion timing, and peripheral module timing. The device uses an external crystal or ceramic resonator connected to the XIN/XOUT pins, with internal oscillator circuitry supporting stable startup and jitter-free operation within industrial temperature ranges.
Does the HD6473278PJ10 include an on-chip A/D converter, and what are its specifications?
Yes, the HD6473278PJ10 integrates an 8-channel, 10-bit successive-approximation A/D converter. It supports both single-conversion and scan modes, with a maximum conversion time of 22.2 µs and ±1 LSB integral nonlinearity. Inputs AN0–AN7 accept 0–5 V analog signals, and conversion can be triggered internally or by external events such as timer overflow or external interrupt - enabling precise synchronization in motor control applications.
What power-saving modes does the HD6473278PJ10 support, and how low is the standby current?
The HD6473278PJ10 supports three hardware-controlled power-down modes: Sleep, Software Standby, and Hardware Standby. In Hardware Standby mode, supply current drops below 10 µA at 5 V and 25°C - verified per Section 12.5 of the hardware manual. These modes are activated via SYSCR and MDCR register bits and retain RAM contents, allowing fast wake-up (<10 µs) on external interrupt or reset, making HD6473278PJ10 suitable for battery-powered instrumentation.
Is the HD6473278PJ10 pin-compatible with other devices in the H8/327 series?
Yes, the HD6473278PJ10 shares identical pinout, package (64-pin PQFP), and memory map with all members of the H8/327 family, including HD6433278 and HD6413278. This allows direct substitution in PCB layouts when migrating between masked ROM, ZTAT™, or ROMless variants - provided external circuitry (e.g., pull-ups, clock source) matches the operational mode requirements specified in Section 2 of the hardware manual.
What development tools and documentation are available for the HD6473278PJ10?
Official support for the HD6473278PJ10 includes the H8/329 Series Hardware Manual (OMC942723054), H8/300 Series Programming Manual, and evaluation boards such as the E07722 (H8/327 target board). Renesas provides legacy toolchains including the High-performance Embedded Workshop (HEW) IDE and associated C compiler and debugger.
