Product details
Overview
HD6473614HV from Renesas Electronics is a single-chip 16-bit microcontroller in the H8/3614 Series, featuring an H8/300L CPU core, 128 KB mask ROM, 8 KB RAM, 14-bit PWM, dual SCI interfaces (SCI1/SCI2), and a 10-channel 10-bit A/D converter. It operates at up to 20 MHz and supports multiple low-power modes including Sleep, Standby, and Watch modes for embedded control applications.
For engineers reviewing the HD6473614HV datasheet, HD6473614HV pinout, HD6473614HV application, or HD6473614HV equivalent, key selection criteria include on-chip memory size, peripheral integration (dual serial interfaces + PWM + ADC), clock flexibility (main/subclock generators), and industrial-grade temperature range (–40°C to +85°C) with HV-grade voltage tolerance.
Technical Context
The HD6473614HV implements the H8/300L CPU architecture with 16-bit data bus, 24-bit address space (16 MB), and Harvard-style memory mapping. It integrates system-level peripherals including five independent timers (Timer A–E), programmable I/O ports (Ports 0, 1, 2, 4, 8, 9, A), and dedicated clock pulse generators for main and subclock domains.
Peripheral control is managed via memory-mapped registers with defined reset values and bit-field access conventions. The device supports exception handling with 16 priority levels, vectorized interrupts, and configurable stack usage per mode-critical for deterministic real-time response in motor control and industrial automation systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3614FV | Same H8/3614 architecture but with 128 KB flash memory instead of mask ROM; supports in-system programming. | Preferred for prototyping and low-volume production where firmware updates are required. | Select HD64F3614FV when field firmware upgrades or iterative development are needed; HD6473614HV is optimal for high-volume, fixed-function deployments. |
| HD6433614 | Identical pinout and peripheral set, but rated for commercial temperature range (0°C to +70°C) and standard voltage (4.0–5.5 V). | Suitable for cost-sensitive consumer or office equipment where extended temperature and HV tolerance are unnecessary. | Choose HD6433614 for non-industrial environments; HD6473614HV adds reliability margin for harsh electrical/thermal conditions. |
Compared with HD64F3614FV and HD6433614, the HD6473614HV trades flash programmability and commercial grading for higher voltage tolerance and industrial temperature qualification - making it the preferred choice for unattended, long-lifecycle embedded systems where firmware stability and environmental resilience are critical.

FAQ
What is the maximum operating frequency of the HD6473614HV?
The HD6473614HV operates at a maximum CPU clock frequency of 20 MHz, achieved using the on-chip PLL driven by an external crystal connected to XIN/XOUT. This frequency is supported across the full industrial temperature range (–40°C to +85°C) and supply voltage range (4.5 V to 5.5 V), ensuring deterministic timing for real-time control loops in motor and power applications.
Does the HD6473614HV support in-system programming (ISP)?
No, the HD6473614HV contains 128 KB of mask ROM, which is factory-programmed and not reprogrammable in the field. For ISP capability, consider the flash-based HD64F3614FV variant, which shares the same peripheral set and pinout but replaces mask ROM with 128 KB on-chip flash memory.
How many A/D input channels does the HD6473614HV have, and what is their resolution?
The HD6473614HV integrates a 10-bit successive-approximation A/D converter with 10 analog input channels (AD0–AD9), mapped across Ports 8 and 9. Conversion time is guaranteed at ≤10 μs per sample, and triggering can be performed via software, timer match, or external signal - enabling synchronized sampling in sensor-rich industrial applications.
What low-power modes are available on the HD6473614HV?
The HD6473614HV supports five low-power modes: Active, Sleep, Standby, Watch, and Subactive. In Watch mode, the subclock (32.768 kHz) remains active to maintain RTC functionality while CPU and most peripherals halt, drawing less than 10 μA. This makes HD6473614HV suitable for battery-backed monitoring applications with multi-year runtime requirements.
Is the HD6473614HV pin-compatible with other H8/3614 family members?
Yes, the HD6473614HV shares identical pinout and package (100-pin LQFP) with HD6433614 and HD64F3614FV. All three variants support the same peripheral register map and memory layout, allowing hardware design reuse across mask ROM, flash, and commercial-grade versions - though voltage and temperature ratings differ.
