Product details
Overview
HD6433663FPJV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 64 KB on-chip ROM, 4 KB RAM, and integrated peripherals including UART, timer/counters, and I/O ports. It operates at up to 20 MHz and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the HD6433663FPJV datasheet, HD6433663FPJV pinout, HD6433663FPJV application, or HD6433663FPJV equivalent, key selection considerations include its 80-pin PQFP package, 5 V operation, on-chip flash programming capability, and support for low-power sleep/standby modes in resource-constrained systems.
Technical Context
The HD6433663FPJV implements the H8/300H CPU architecture with 16-bit data bus and 24-bit address space, supporting both big-endian and little-endian memory access via software configuration. It integrates a system clock generator with crystal, ceramic, or external clock input options, plus subclock circuitry for real-time clock functions using a 32.768 kHz resonator.
Peripheral modules include three 16-bit timer/counters (one with PWM output), two asynchronous serial interfaces (UART), and 64 general-purpose I/O pins configurable as inputs, outputs, or alternate-function signals. Power management is handled through SYSCR1/SYSCR2 registers enabling Sleep, Standby, Subsleep, and Subactive modes with defined wake-up sources and latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8/300H 16-bit RISC core, instruction-compatible with H8/300, enabling legacy code reuse and toolchain continuity. |
| ROM Capacity | 64 KB on-chip mask ROM - fixed program storage eliminating external memory footprint and boot time delays. |
| RAM Size | 4 KB on-chip RAM - sufficient for stack, variables, and small buffers in real-time control loops without external SRAM. |
| Max Operating Frequency | 20 MHz - supports deterministic timing for motor control, sensor polling, and communication protocols at industrial speeds. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic systems and tolerant of supply ripple in noisy environments. |
| I/O Pins | 64 programmable I/O pins - enables direct interface to displays, switches, sensors, and actuators without glue logic. |
| Package | 80-pin plastic quad flat pack (PQFP) - surface-mount compatible with standard reflow profiles and PCB assembly processes. |
Pinout & Package
HD6433663FPJV is housed in an 80-pin PQFP (Plastic Quad Flat Package) with 0.65 mm lead pitch, JEDEC MS-026 compliant, suitable for automated SMT placement and reflow soldering. Thermal resistance θJA = 45°C/W enables operation up to +70°C ambient without forced cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated power/ground pairs per quadrant reduce noise coupling and ensure stable core/peripheral voltage under dynamic load. |
| XTAL1/XTAL2 | Crystal oscillator input/output | Supports fundamental-mode quartz crystals (1–20 MHz) or ceramic resonators for precise system clock generation. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers and initializes I/O states; internal pull-up ensures defined startup without external resistor. |
| INT0–INT7 | External interrupt inputs | Edge-selectable (rising/falling) interrupts with dedicated vector addresses enable responsive event handling for buttons, encoders, or fault signals. |
| TXD0/RXD0 | UART channel 0 transmit/receive | Full-duplex asynchronous serial interface supporting RS-232/RS-485 level-shifting for diagnostics or host communication. |
| P00–P77 | General-purpose I/O ports | Eight 8-bit bi-directional ports with individual direction control and read-modify-write capability for flexible peripheral interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip ROM with boot mode selection | Enables secure, tamper-resistant firmware execution and eliminates external boot ROM dependency during power-on initialization. |
| Three 16-bit timer/counters with PWM output | Provides precise pulse-width modulation for DC motor speed control, LED dimming, or power converter gate drive without external ICs. |
| Dual UART with selectable baud rates | Supports simultaneous debug logging and host command interface at independent baud rates (e.g., 9600 bps for control, 115200 bps for telemetry). |
| Four power-down modes (Sleep, Standby, Subsleep, Subactive) | Reduces active current to <10 µA in Standby mode while retaining RAM content and enabling wake-up via external interrupt or timer match. |
| System clock generator with subclock support | Allows concurrent high-speed CPU operation and low-power RTC functionality using separate 32.768 kHz crystal for calendar/timekeeping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3664F | Same H8/3664 family but with 128 KB ROM and 8 KB RAM; identical pinout and peripheral set. | Higher memory capacity suits firmware with larger GUI or protocol stacks (e.g., Modbus TCP). | Select HD64F3664F when application requires >64 KB code space or extended data buffering without changing PCB layout. |
| HD6433662FPJV | Lower-density variant: 32 KB ROM, 2 KB RAM, same 80-pin PQFP package and peripheral complement. | Targeted at cost-sensitive designs with simpler control logic and minimal feature set. | Choose HD6433662FPJV for legacy replacement where existing firmware fits within reduced memory and no new features are needed. |
Compared with HD6433663FPJV, HD64F3664F offers double the ROM/RAM for future-proofing at identical pin compatibility, while HD6433662FPJV provides a lower-cost path for functionally equivalent but memory-constrained implementations-both retain full peripheral and timing compatibility.

FAQ
What is the maximum operating frequency of the HD6433663FPJV?
The HD6433663FPJV supports a maximum operating frequency of 20 MHz when powered at 4.5–5.5 V. This frequency is achieved using the on-chip system clock generator with an external crystal or ceramic resonator connected to XTAL1/XTAL2. The CPU executes instructions at this rate with deterministic timing, making HD6433663FPJV suitable for real-time control loops requiring sub-50 µs response intervals.
Does the HD6433663FPJV support in-system programming?
No, the HD6433663FPJV contains mask-programmed ROM and does not support in-system or field reprogramming. Firmware is permanently written during manufacturing. For field-upgradable alternatives, consider flash-based variants like HD64F3664F. HD6433663FPJV is intended for high-volume, fixed-function applications where code stability and security are prioritized over update flexibility.
What power management modes does the HD6433663FPJV offer?
The HD6433663FPJV provides four hardware-controlled power-down modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained), Subsleep (subclock active only), and Subactive (subclock running with limited CPU activity). Wake-up is supported via external interrupt, timer match, or NMI. In Standby mode, current drops below 10 µA, enabling battery-backed operation in portable equipment using HD6433663FPJV.
Is the HD6433663FPJV pin-compatible with other H8/366x devices?
Yes, HD6433663FPJV shares the same 80-pin PQFP package and pin assignment with other members of the H8/366x series, including HD6433662FPJV and HD64F3664F. Signal names, power/ground locations, and peripheral pin mappings are identical across these variants, allowing PCB reuse when migrating between memory sizes or ROM vs. flash configurations-provided firmware and system-level timing constraints are verified.
What development tools are recommended for the HD6433663FPJV?
Renesas recommends the E8 emulator for HD6433663FPJV hardware debugging and the High-performance Embedded Workshop IDE with H8/300H C/C++ compiler (REJ10B0026). Since HD6433663FPJV lacks on-chip debug interfaces beyond NMI and dedicated emulator pins (P85–P87), external emulation via E8 is required for full visibility into register states and memory. The H8/300H Series Software Manual (REJ09B0213) is essential for instruction-level optimization of HD6433663FPJV firmware.
