Product details
Overview
HD6473614PV from Renesas Electronics is a single-chip 16-bit microcontroller based on the H8/300L CPU core, featuring 128 KB mask ROM, 4 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 in industrial sensors and motor drives.
For engineers reviewing the HD6473614PV datasheet, HD6473614PV pinout, HD6473614PV application, or HD6473614PV equivalent, key selection criteria include its integrated 14-bit PWM resolution, dual asynchronous serial channels with independent clocking, 10-bit A/D conversion accuracy, and support for ZTAT™ (Zero Time Access Technology) ROM variants with identical timing behavior.
Technical Context
The HD6473614PV implements the H8/300L 16-bit CISC architecture with 24-bit addressing space, 16 general-purpose registers, and hardware-supported exception handling including reset, maskable interrupts, and internal exception vectors. Its peripheral set includes five 16-bit timers (A–E), programmable I/O ports with pull-up MOS control, and system-level clock generators supporting main/subclock switching.
It integrates dedicated hardware blocks for serial communication (SCI1/SCI2), analog-to-digital conversion (10-bit, 10-channel, 1.6 µs conversion time), and high-resolution pulse-width modulation (14-bit, 4-channel output). All peripherals are memory-mapped and accessible via fixed register addresses defined in the H8/3614 Series Hardware Manual (OMC942723157).

| AD0–AD9 | Analog input channels | 10 dedicated pins mapped to internal 10-bit A/D converter - require external signal conditioning per channel |
| TO0–TO3 | PWM output terminals | Four dedicated outputs from 14-bit PWM module - support complementary mode with dead-time insertion for motor gate drive |
Key Features
| Feature | Design Value |
|---|---|
| ZTAT™ ROM technology | Enables zero-wait-state execution at 20 MHz without external wait-state generation logic |
| Five 16-bit timers (A–E) | Support input capture, output compare, PWM generation, and interval counting with independent prescalers |
| Dual SCI interfaces | Each SCI has separate baud-rate generators, status/control registers, and interrupt sources - allows concurrent host and peripheral communication |
| Low-power operation modes | Sleep (CPU halted, peripherals active), Standby (all clocks stopped except subclock), Watch (subclock only, RTC-capable) - reduces current to <10 µA |
| On-chip debug interface | Supports background debugging via dedicated pins and BDM protocol - no emulator required for firmware development |

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 uses Flash ROM (256 KB) instead of mask ROM; requires different programming workflow and has higher standby current | Preferred for prototyping and low-volume production where firmware updates are required; not suitable for cost-sensitive high-volume mask-ROM deployments | Select HD64F3614FV when field firmware upgrades or design iteration are needed; HD6473614PV remains optimal for fixed-function, high-volume industrial controllers. |
| HD6433614FP | Identical mask ROM size and peripheral set, but in 80-pin PQFP package - lacks 20 pins including 4 A/D channels and 2 SCI control signals | Used in space-constrained designs with reduced analog I/O count and single SCI requirement; incompatible with full-feature HD6473614PV PCB layouts | Choose HD6433614FP only if application omits AD5–AD9 and SCI2 functionality; verify pin compatibility before migration. |
Compared with HD64F3614FV and HD6433614FP, the HD6473614PV offers the highest analog integration (10-channel A/D), full dual-SCI capability, and lowest unit cost in high-volume mask-ROM production - making it the preferred choice for fixed-feature industrial control applications requiring long-term supply stability.

FAQ
What is the maximum operating frequency of the HD6473614PV?
The HD6473614PV supports a maximum system clock frequency of 20 MHz, enabling instruction execution at up to 10 million instructions per second (MIPS) with zero wait states when using ZTAT™ mask ROM. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) and requires a stable 5 V ±10% supply with proper decoupling.
Does the HD6473614PV include an on-chip debug interface?
Yes, the HD6473614PV integrates a background debug mode (BDM) interface compatible with Renesas E8/E8a emulators. It uses dedicated pins (BKGD, RES#) to support non-intrusive program download, breakpoint setting, and real-time register inspection without requiring additional JTAG hardware or code instrumentation.
How many analog input channels does the HD6473614PV A/D converter support?
The HD6473614PV features a 10-bit successive approximation A/D converter with 10 dedicated analog input channels (AD0–AD9), each mapped to a physical pin. These channels support simultaneous sampling control via software trigger or timer event, with conversion results stored in the A/D Result Register (ADRR) and interrupt generation upon completion.
What low-power modes are available on the HD6473614PV?
The HD6473614PV provides five low-power modes: Active (full operation), Sleep (CPU halted, peripherals active), Standby (all clocks stopped except subclock), Watch (subclock only, RTC-enabled), and Subactive (reduced-speed main clock). Current consumption drops to less than 10 µA in Watch mode, making it suitable for battery-backed monitoring applications.
Is the HD6473614PV pin-compatible with other H8/3614 family members?
No - the HD6473614PV is specifically packaged in a 100-pin PQFP and is not pin-compatible with 80-pin variants like HD6433614FP. Pin assignments for A/D inputs, SCI signals, and timer outputs differ across package options. Migration requires PCB layout revision and validation of signal routing, power integrity, and thermal performance.
