The MC68HC705P6ECP is an 8-bit microcontroller manufactured by Freescale Semiconductor (now NXP). It's part of the MC68HC05 family, popular for their cost-effectiveness and use in a wide range of embedded applications. The P6 variant is specifically designed for low-power and cost-sensitive applications.

Applications

• Low-power consumer electronics (e.g., battery-operated toys, remote controls).
• Simple appliance control (e.g., timers, basic motor control).
• Security systems (e.g., entry-level alarm systems).
• Industrial control applications (e.g., sensor interfaces, basic process control).
• Automotive applications (e.g., simple dashboard functions).

Features

• 8-bit CPU core (MC68HC05 architecture).
• 3776 bytes of EPROM for program storage.
• 176 bytes of RAM for data storage.
• 20 Input/Output (I/O) pins, configurable for various functions.
• 8-bit Timer with prescaler.
• Serial Communications Interface (SCI) for UART communication.
• On-chip oscillator.
• Low-voltage inhibit (LVI) for preventing operation at insufficient voltage levels.
• Power-saving STOP and WAIT modes.

Benefits

• Cost-effective solution for embedded control.
• Easy to program and use due to the well-documented MC68HC05 architecture.
• Integrated peripherals reduce the need for external components, simplifying design.
• Very low power consumption, ideal for battery-powered applications.
• EPROM allows for program updates and modifications.

Additional Details

The MC68HC705P6ECP typically operates at clock speeds up to 4 MHz. The 'ECP' suffix indicates a specific package type, likely a PDIP (Plastic Dual In-line Package). It requires a 5V power supply. Consult the Freescale/NXP datasheet for complete specifications, timing diagrams, and pinout information. Key design considerations include minimizing power consumption through effective use of the STOP and WAIT modes, managing interrupt routines, and configuring the I/O ports appropriately.
