Product details
Overview
HD6473802PV from Renesas Technology Corp. is an 8-bit single-chip microcontroller in the H8/3802 Group, featuring a 16 kB mask ROM, 1 kB RAM, and a 16 MHz maximum operating frequency at 4.5–5.5 V supply. It integrates 51 general-purpose I/O pins, one 10-bit A/D converter with four channels, one UART (SCI), three timers (Timer A, Timer F, AEC), and a watchdog timer. It targets low-power embedded control applications such as industrial sensor interfaces and appliance motor controllers.
For engineers reviewing the HD6473802PV datasheet, HD6473802PV pinout, HD6473802PV application, or HD6473802PV equivalent, this page delivers verified technical identity, package mapping to FP-64A, confirmed pin functions including P95–P90 output port and IRQAEC interrupt input, real-time clocking options (external crystal or ceramic resonator), and two validated alternative parts for design continuity.
Technical Context
The HD6473802PV implements the H8/300L CPU core with full instruction set compatibility to the H8/300, enabling legacy code reuse. Its on-chip peripheral set includes a 10-bit × 4-channel ADC, UART-based SCI interface, and three independent timers supporting PWM generation, event counting, and system supervision.
It operates in five power modes-active, sleep, subactive, subsleep, and watch-with programmable standby timing (up to 8,192 states) and supports external crystal (4–10 MHz) or ceramic resonator (4.193 MHz typical) clock sources. The device lacks on-chip oscillator, POR, or LVD circuits-features reserved for the H8/38104 Group.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300L 8-bit RISC core, instruction-compatible with H8/300 for seamless migration |
| ROM Size | 16 kB mask ROM - fixed firmware storage, no field reprogramming capability |
| RAM Size | 1 kB SRAM (address range H'FB80–H'FF7F) - sufficient for real-time control stacks and buffers |
| Max Clock Frequency | 16 MHz at 4.5–5.5 V - enables deterministic 62.5 ns instruction cycle time |
| I/O Pins | 51 total I/O: 9 input-only, 6 output-only, 51 bidirectional - supports mixed-signal peripheral interfacing |
| A/D Converter | 10-bit resolution × 4 channels - suitable for analog sensor acquisition (e.g., temperature, voltage) |
| Serial Interface | 1-channel SCI (UART mode only) - provides asynchronous host communication without hardware flow control |
| Timers | Timer A (clock), Timer F (compare), AEC (asynchronous event counter) - enables PWM, timebase, and edge-triggered wake-up |
Pinout & Package
HD6473802PV is housed in a 64-pin plastic flat package (FP-64A), compliant with JEDEC MS-026AC, with 0.5 mm lead pitch and exposed thermal pad. Pin assignment follows standard H8/3802 Group layout; NC pins must remain unconnected per Renesas handling guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply inputs | Core logic supply (4.5–5.5 V); multiple VSS pins ensure low-impedance ground return |
| OSC1, OSC2 | Crystal/resonator interface | Connects external 4–10 MHz crystal or ceramic resonator; internal feedback circuit enables self-oscillation |
| RES | Active-low reset input | Asynchronous reset assertion halts CPU and initializes registers; requires ≥10 system clock cycles low pulse |
| P95–P90 | Output-only port | 6-bit high-voltage, large-current port (H8/3802-specific); drives LEDs, relays, or discrete transistors directly |
| IRQAEC | Asynchronous event counter input | Edge-triggered interrupt pin for external pulse counting (e.g., encoder signals, tachometer inputs) |
| PB3–PB0 | Analog input / external interrupt | Four-channel 10-bit ADC inputs with IRQ1 capability; PB0/PB1 also serve as LVD reference inputs on other variants (not active on HD6473802PV) |
Key Features
| Feature | Design Value |
|---|---|
| Low-power operation modes | Five configurable states (active, sleep, subactive, subsleep, watch) with programmable wake-up latency up to 8,192 clock cycles |
| On-chip A/D converter | 10-bit resolution across four channels with sample-and-hold; conversion time ≤ 25 µs at 16 MHz |
| Hardware SCI interface | Full-duplex UART supporting baud rates from 1,200 to 19,200 bps; no RS-232 level shifting required |
| Dedicated high-drive I/O | P95–P90 output port delivers >20 mA sink/source per pin - eliminates need for external driver transistors |
| Watchdog timer | Configurable timeout period using φ/8,192 or φw/32 clock source - prevents software lockup in safety-critical loops |
Applications
| Industrial Sensor Node | Home Appliance Motor Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F38004 | 32 kB flash memory instead of 16 kB mask ROM; supports in-system programming | Field-upgradable firmware; suited for prototyping and low-volume production | Select when firmware updates are required post-deployment or during development iteration |
| HD64338002 | 16 kB mask ROM, same RAM and peripherals, but packaged in DP-64S (die form) - no leaded package | Intended for custom hybrid modules or embedded die-on-PCB integration | Select only for OEM applications with internal assembly capability and no requirement for standard surface-mount packaging |
Compared with HD6473802PV, HD64F38004 offers field-programmable flash at the cost of higher minimum order quantities and longer write/erase cycles, while HD64338002 sacrifices standard FP-64A packaging for die-level integration-neither is pin-compatible, but both share identical register maps and peripheral behavior.

FAQ
What is the maximum operating frequency and supply voltage range for HD6473802PV?
The HD6473802PV operates at up to 16 MHz with a supply voltage range of 4.5 V to 5.5 V. This specification is defined in the H8/3802 Group Hardware Manual Rev. 4.00, and applies strictly to the HD6473802PV variant-not the H8/38104 or H8/38004 Groups which support wider voltage ranges. Operation outside this window may cause undefined behavior or failure to execute instructions correctly.
Does HD6473802PV include an on-chip oscillator or power-on reset (POR) circuit?
No, HD6473802PV does not include an on-chip oscillator or POR circuit. These features are exclusive to the H8/38104 Group per the Hardware Manual Rev. 4.00. HD6473802PV requires an external crystal or ceramic resonator connected to OSC1/OSC2 and relies on external reset circuitry for reliable power-on initialization.
Can HD6473802PV be programmed in-system like flash-based variants?
No, HD6473802PV contains 16 kB of mask ROM, which is factory-programmed and read-only. In-system programming is not supported. For field-upgradable firmware, consider HD64F38004 (32 kB flash) or HD64F38002 (16 kB flash), both of which share the same H8/3802 architecture and peripheral set as HD6473802PV.
What are the key differences between HD6473802PV and HD64F38004?
HD6473802PV uses 16 kB mask ROM and is OTP/fixed-function; HD64F38004 uses 32 kB flash memory, enabling firmware updates. Both share identical I/O count, timer resources, ADC specs, and FP-64A packaging-but HD64F38004 requires different programming voltages and erase procedures. Their register maps and instruction sets are fully compatible.
Is the P95–P90 port on HD6473802PV capable of driving high-current loads directly?
Yes, the P95–P90 port on HD6473802PV is a dedicated high-voltage, large-current output port (per H8/3802 Group documentation), capable of sourcing/sinking >20 mA per pin. This allows direct connection to LEDs, small relays, or MOSFET gates without external buffer transistors-unlike standard GPIO ports on most 8-bit MCUs.
