Product details
Overview
HD6473032VFJ12 from Renesas Electronics (formerly Hitachi) is a 16-bit single-chip microcontroller based on the H8/300H CPU core, featuring 128 KB on-chip ROM, 8 KB RAM, a 16-bit ITU timer, programmable TPC, SCI serial interface, 10-bit A/D converter, and watchdog timer. It operates at up to 20 MHz and supports single-chip and expanded modes for industrial control and embedded instrumentation.
For engineers reviewing the HD6473032VFJ12 datasheet, HD6473032VFJ12 pinout, HD6473032VFJ12 application, or HD6473032VFJ12 equivalent, key selection criteria include its 100-pin QFP package, 1 Mbyte address space, integrated peripheral set, and legacy industrial firmware compatibility.
Technical Context
The HD6473032VFJ12 implements the H8/300H 32-bit internal architecture with sixteen 16-bit general-purpose registers and a linear 1 Mbyte address space - not 16 Mbyte as in higher-end H8 variants. Its CPU supports three operating modes (Mode 1–3), each configuring external bus behavior and memory mapping via MDCR and SYSCR registers.
On-chip peripherals include a 16-bit Integrated Timer Unit (ITU) supporting PWM, phase counting, and complementary output modes; a Programmable Timing Pattern Controller (TPC) for precise waveform generation; and an SCI module compatible with asynchronous serial communication at configurable baud rates. All modules are memory-mapped and accessible via 16-bit or 8-bit I/O instructions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3032FV | Same pinout and memory map; flash-based (not mask ROM); requires external programming voltage | Enables field firmware updates but increases BOM cost and board complexity | Select when firmware revision flexibility outweighs production cost and security requirements |
| R5F100LEA | RL78/G13 16-bit core; lower power (1.8–5.5 V), smaller footprint (64-pin LQFP); no TPC or ITU PWM complement mode | Suitable for battery-powered or space-constrained designs where advanced motor timing is not required | Select for new low-power designs where legacy H8 toolchain compatibility is not mandatory |
Compared with HD6473032VFJ12, HD64F3032FV offers field-programmable flash but lacks mask-ROM security and cost efficiency at volume, while R5F100LEA reduces power and size but omits TPC and complementary PWM - making HD6473032VFJ12 irreplaceable for legacy industrial motor drives requiring hardware-dead-time control.

FAQ
What is the maximum operating frequency of the HD6473032VFJ12?
The HD6473032VFJ12 operates at a maximum clock frequency of 20 MHz. This rating is validated across the full industrial temperature range (−40°C to +85°C) and 4.5 V to 5.5 V supply voltage. The CPU's instruction cycle time is 50 ns at this frequency, enabling sub-1 µs interrupt response for time-critical control tasks. HD6473032VFJ12 does not support overclocking beyond this specification.
Does the HD6473032VFJ12 include on-chip flash memory?
No, the HD6473032VFJ12 uses mask-programmed ROM for program storage, not flash memory. Its 128 KB ROM is programmed during wafer fabrication and cannot be reprogrammed in-system. This provides immunity to accidental overwrite and ensures firmware integrity in harsh environments - a key requirement for industrial safety-critical applications where HD6473032VFJ12 is deployed.
Can the HD6473032VFJ12 generate complementary PWM signals with programmable dead time?
Yes, the HD6473032VFJ12's Integrated Timer Unit (ITU) supports Complementary PWM Mode, allowing generation of paired high-side/low-side gate drive signals. However, dead time insertion is implemented in software via timer compare register updates - the hardware does not provide automatic dead-time generation. This capability is explicitly documented in Section 8.4.6 of the H8/3032 Hardware Manual for HD6473032VFJ12.
What serial communication protocols does the HD6473032VFJ12 support?
The HD6473032VFJ12 includes a Serial Communication Interface (SCI) module supporting asynchronous full-duplex UART-style communication only. It does not implement SPI, I²C, CAN, or LIN protocols. Baud rate is programmable via internal divisor registers, and the SCI supports framing error detection, parity checking, and break detection - features confirmed for HD6473032VFJ12 in Section 11 of the official hardware manual.
Is the HD6473032VFJ12 pin-compatible with other H8/3032 family members?
HD6473032VFJ12 is pin-compatible with HD64F3032FV (flash variant) in the same 100-pin QFP package, sharing identical pin functions, power sequencing, and reset behavior. It is not pin-compatible with smaller-package variants (e.g., 80-pin versions) or unrelated H8 families like H8/3048. This compatibility is verified in the Pin Arrangement section (1.3.1) of the HD6473032VFJ12 hardware manual.
