Product details
Overview
HD6473214P16V from Renesas Technology Corp. is a single-chip 16-bit microcontroller in the H8/3214 family, built on the H8/300 CPU core and designed for embedded industrial control. It integrates 32 KB on-chip ROM, 1 KB RAM, four timer types (PWM, 16-bit free-running, dual 8-bit), I²C bus interface, serial communication, and 48 general-purpose I/O pins. It operates at up to 20 MHz and supports ZTAT™ electrically programmable ROM for rapid firmware iteration in factory automation systems.
For engineers reviewing the HD6473214P16V datasheet, HD6473214P16V pinout, HD6473214P16V application, or HD6473214P16V equivalent, key selection criteria include on-chip memory size, I²C and UART peripheral availability, PWM channel count, interrupt latency, and compatibility with legacy H8/300 toolchains and debug infrastructure.
Technical Context
The HD6473214P16V implements the H8/300H instruction set architecture with 24-bit addressing, supporting up to 16 MB of linear address space. Its internal bus architecture enables zero-wait-state access to on-chip ROM and RAM when operating at ≤20 MHz with appropriate wait-state configuration.
It features a dedicated wait-state controller, clock pulse generator with internal oscillator support (1–20 MHz), and system control registers (SYSCR, MDCR) that configure power-down modes, reset behavior, and exception vector mapping. All timers share a common prescaler and support input capture, output compare, and PWM waveform generation with polarity control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3214FV | Same H8/3214 family but with flash memory instead of ROM; requires different programming voltage and erase sequencing | Preferred for prototyping and low-volume production where firmware revision frequency exceeds 10×/year | Select HD64F3214FV only if field reprogrammability without ZTAT™ timing constraints is required |
| R5F33214ADFP | Renesas RL78/G13 derivative with enhanced low-power modes, 10-bit ADC, and integrated debug interface-but not instruction- or pin-compatible | Suitable for new designs prioritizing energy efficiency and mixed-signal integration over legacy code reuse | Choose R5F33214ADFP for greenfield projects needing <1 µA deep standby current and on-chip ADC, not for drop-in replacement |
Compared with HD64F3214FV and R5F33214ADFP, the HD6473214P16V delivers deterministic ZTAT™ programming latency and guaranteed pinout compatibility with legacy H8/3214 hardware, making it the sole option for certified industrial retrofits requiring zero PCB changes and unchanged toolchain dependencies.

FAQ
What is the maximum operating frequency of the HD6473214P16V?
The HD6473214P16V supports a maximum system clock frequency of 20 MHz. This rating assumes proper decoupling, ambient temperature ≤70°C, and VCC = 5.0 V ±5%. At this speed, the H8/300H core executes most instructions in one or two clock cycles, enabling sub-100 ns interrupt response times critical for closed-loop motor control. The HD6473214P16V clock pulse generator accepts direct crystal or external clock input without internal PLL multiplication.
Does the HD6473214P16V support in-system programming (ISP)?
Yes-the HD6473214P16V features ZTAT™ (Zero Turn-Around Time) electrically programmable ROM, enabling in-system firmware updates via standard UART or parallel programming interfaces without removing the device from the board. Unlike flash-based alternatives, ZTAT™ requires no erase cycle before write, allowing byte-level modifications with typical programming times under 10 ms per 256-byte block. This capability is fully supported in the HD6473214P16V hardware design.
What peripherals are integrated into the HD6473214P16V?
The HD6473214P16V integrates a 16-bit free-running timer, two independent 8-bit timers, a 16-channel PWM unit, an I²C bus interface, an asynchronous serial interface (UART), and 48 general-purpose I/O pins distributed across seven ports. All peripherals are memory-mapped and accessible via dedicated control registers. No external glue logic is required to use these functions-each is enabled and configured entirely through the HD6473214P16V's internal register set.
Is the HD6473214P16V pin-compatible with other H8/3214 variants?
Yes-the HD6473214P16V uses the same 64-pin LQFP package and identical pin assignment as all members of the H8/3214 family, including HD64F3214FV and HD6473214FP. Signal names, electrical characteristics, and timing parameters match across variants, enabling direct substitution in existing PCB layouts. This compatibility is explicitly documented in the H8/3214 Hardware Manual and verified in Renesas' official migration guides for the HD6473214P16V.
What development tools support the HD6473214P16V?
The HD6473214P16V is supported by Renesas' legacy H8/300 toolchain, including the High-performance Embedded Workshop (HEW) IDE, C compiler (H8/300 ANSI C), and E8/E8a in-circuit emulators. Debugging is performed via the on-chip debug interface using standard JTAG signals routed to dedicated pins. Third-party tools like IAR Embedded Workbench also provide certified HD6473214P16V support with full peripheral register views and real-time trace.
