Renesas HD6473867HV

Overview

HD6473867HV from Renesas Technology Corp. is a 16-bit single-chip microcomputer in the H8/3867 Series, featuring an integrated LCD controller/driver, six timers, 14-bit PWM, dual-channel SCI, and 8-channel 10-bit A/D converter. It operates at up to 16 MHz with on-chip step-up power supply (5 V) for LCD bias, targeting embedded display systems requiring self-contained timing and drive capability.

For engineers reviewing the HD6473867HV datasheet, HD6473867HV pinout, HD6473867HV application, or HD6473867HV equivalent, key selection criteria include its integrated LCD power supply, subclock support (32.768 kHz), sleep/standby/wake modes, and compatibility with H8/300L instruction set - all critical for low-power portable instrumentation and industrial HMI designs.

Technical Context

The HD6473867HV implements the H8/300L CPU core with full instruction set compatibility and supports multiple clock sources: main system clock (up to 16 MHz), subclock (32.768 kHz or 38.4 kHz), and internal oscillator. Its power management includes five operating modes - active, subactive, sleep, standby, and subsleep - each with distinct clock gating and peripheral enable control.

Hardware peripherals are tightly coupled to the CPU via on-chip bus architecture: Port 3 supports segment/common LCD drive outputs, Port 1–8 provide configurable I/O with MOS input pull-up, and SCI3 supports both asynchronous and synchronous serial communication with programmable bit rates up to 1 Mbps at 16 MHz.

FAQ

What is the operating temperature range for HD6473867HV?

The HD6473867HV is specified for industrial temperature operation from −40°C to +85°C. This rating ensures reliable performance in factory automation equipment, outdoor meters, and other harsh-environment applications where thermal stability is critical. The HD6473867HV maintains full functionality across this range, including LCD drive output accuracy and A/D conversion linearity.

Does HD6473867HV include on-chip flash memory?

No, HD6473867HV contains mask-programmed ROM, not flash memory. It is a fixed-function microcontroller intended for high-volume production where firmware is finalized before manufacturing. For reprogrammable variants, consider the HD64F3867HV, which shares the same pinout and peripheral set but uses on-chip flash instead of mask ROM.

Can HD6473867HV drive a 1/4-duty, 1/3-bias LCD without external components?

Yes, HD6473867HV integrates a step-up DC-DC converter that generates a stable 5 V LCD bias supply, enabling direct drive of 1/4-duty, 1/3-bias LCDs up to 32 segments × 4 commons. No external charge pump or voltage regulator is required, reducing bill-of-materials and layout complexity in compact display modules.

What clock sources does HD6473867HV support?

HD6473867HV supports three clock domains: main system clock (1–16 MHz via XTAL/EXTAL), subclock (32.768 kHz or 38.4 kHz via CLKIN/CLKOUT), and internal RC oscillator. The subclock enables RTC and ultra-low-power subsleep mode, while the main clock drives CPU and peripherals at full speed.

Is HD6473867HV pin-compatible with other H8/3867 Series devices?

Yes, HD6473867HV shares the same 100-pin PQFP package and pin assignment with other members of the H8/3867 Series, including HD64F3867HV and HD6433867. This allows hardware design reuse across mask ROM, flash, and commercial-grade variants - though firmware and temperature qualification must be verified per part number.
