HD64F3687GFPV - H8/300H 16-bit MCU, 56KB Flash, 20MHz | Renesas
MPN: HD64F3687GFPV ✓ Hoạt độngHD64F3687GFPV Tóm tắt
What is an H8/300H microcontroller? The H8/300H is Renesas' enhanced 16-bit CISC CPU family, upward-object-code-compatible with the original H8/300 while adding a wider 16-bit register file and richer addressing modes. Tiny-Series derivatives such as the H8/3687 Group position this MCU in the hierarchy: H8 family -> H8/300 CPU -> H8/300H Tiny -> H8/3687 Group, used as mainstream microcontrollers -> embedded systems -> semiconductor ICs. The Flash variant (-F suffix) integrates user-programmable Flash memory suitable for prototyping and field-upgradable production firmware.
Key features include on-chip Flash program memory, RAM, multiple timers (16-bit and 8-bit), a watchdog timer, and serial interfaces including SCI (asynchronous/synchronous) and I2C bus. The H8/300H core executes most instructions in 2 to 4 states at 20 MHz, achieving roughly 5 to 10 MIPS sustained throughput. The 64-LQFP package exposes a wide parallel I/O bus and dedicated peripheral pins, enabling direct LED/segment-LCD driving, motor control PWM, and external memory interfacing when required.
Typical applications include white-goods motor control (washing machines, air conditioners), consumer appliance key-scan user interfaces, industrial sensor signal conditioning, and small home appliances requiring deterministic real-time control. The integrated timers and SCI/I2C allow direct connection to sensors, inverters, and operator panels without external glue logic.
When designing with this device, follow the H8/3687 Group hardware manual for unused-pin handling (tie all unused CMOS inputs to VCC or GND to prevent pass-through current). Designers migrating from earlier H8/300 parts benefit from object-level upward compatibility for firmware reuse.

Ứng dụng tiêu biểu
HD64F3687GFPV phù hợp cho 6 Áp dụngs: White-Goods Motor Control, Consumer Appliance User Panels, Industrial Sensor Signal Conditioning, Small Home Appliance Control, HVAC Climate Control Units, Office Equipment Embedded Control.
White-Goods Motor Control
The HD64F3687GFPV drives single-phase induction and brushless-DC motors in washing machines, dishwashers, and air conditioners. Its 16-bit timer generates complementary PWM with dead-time insertion, while the 53 I/O pins route direction-control signals and current-sense inputs. The 5V tolerance and 4-5.5V supply align with rectified-15V/5V-rail white-goods power trees. Compared with 8-bit MCUs, the H8/300H core delivers roughly 5-10 MIPS at 20 MHz, providing deterministic interrupt latency under simultaneous UART, timer, and ADC servicing typical of inverter control firmware.

Consumer Appliance User Panels
Front-panel key-scan, LED/segment-LCD driving, and rotary-encoder decoding on microwaves, rice cookers, and refrigerators use the HD64F3687GFPV's 53 I/O pins to multiplex 7-segment displays, scan 4x4 key matrices, and drive status LEDs directly. The H8/300H core handles debounce, menu navigation, and SCI-safe timers concurrently. Its 5V I/O tolerance matches indicator LEDs and optocouplers without level shifters, reducing BOM cost.

Industrial Sensor Signal Conditioning
Factory-automation sensor hubs and process-control transmitters use the HD64F3687GFPV to digitize thermocouple, RTD, and 4-20 mA loop inputs while running PID loops at deterministic rates. The 16-bit timer triggers ADC conversions, and the SCI/I2C blocks route processed values to upstream PLCs or HMI panels. The 4.0-5.5V supply accommodates industrial 24V->5V buck rails, and 53 I/O pins support multiple sensor channels per board.

Small Home Appliance Control
Coffee machines, robotic vacuums, and air purifiers use the HD64F3687GFPV to coordinate pump drivers, valve solenoids, heater PWM, and UART-linked sensors. The watchdog timer plus hardware interrupt prioritization handles brown-out events in variable-line-voltage environments. I2C links to environmental sensors (temperature, humidity, gas), and SCI provides diagnostic logging to service tools, simplifying field maintenance.

HVAC Climate Control Units
Split-system air-conditioner indoor units and thermostat controllers use the HD64F3687GFPV to read NTC temperature sensors, IR remote receivers, and triac-fired fan/damper actuators. The H8/300H core executes fuzzy-control algorithms at 20 MHz with sub-millisecond response. SCI links to outdoor-unit communication, while the 16-bit timer generates zero-crossing-synchronized triac triggers for silent fan-speed control.

Office Equipment Embedded Control
Printers, copiers, and label-makers integrate the HD64F3687GFPV to manage stepper-motor paper feeds, thermal printheads, and keypad/display panels. The 53 I/O pins drive parallel printhead strobes and read multiple paper-presence sensors concurrently. SCI provides RS-232/RS-485 service-port connectivity for factory calibration, while I2C links to EEPROM for user-preference storage. The 5V tolerance suits legacy printer power supplies.

Ghi chú thiết kế
Place a 0.1 uF ceramic decoupling capacitor as close as possible to each VCC/AVCC pin pair, with a bulk 10 uF tantalum or aluminum-polymer capacitor near the package. Route the crystal traces (XTAL/EXTAL) short and symmetric, with a guard ground plane underneath to reduce EMI pickup. Keep the reset (RES) trace short and add a 0.1 uF cap near the pin to filter noise.
Per the H8/3687 Group hardware manual, all unused CMOS input pins MUST be tied to either VCC or GND. Leaving them floating induces intermediate levels that cause internal pass-through current and possible malfunction. Also configure the mode pins (MD0/MD1/MD2) correctly before applying power; boot mode selection must match your application (single-chip vs extended).
Estimated: at 20 MHz CPU clock with all peripherals active, core current draw is typically 30-50 mA; sleep-mode current drops below 10 uA when using software standby. Power-decouple the AVCC pin separately from digital VCC with a ferrite bead if ADC channels are used, preventing digital switching noise from coupling into analog references.
When routing SCI/UART lines to RS-232 or RS-485 transceivers, keep trace lengths under 50 mm and add series-termination resistors (22-33 ohm) close to the MCU pins for signals above 1 Mbps. I2C lines should include 4.7 kohm pull-ups to VCC; for bus lengths over 100 mm use 2.2 kohm pull-ups and reduce clock to 100 kHz standard mode.
