    AT89S8253-24AU Typical application Circuitry Schematics


    The AT89S8253-24AU, an 8-bit microcontroller from Microchip, has various interfaces, including ISP (In-System Programming), 3-level program memory lock, 2 expanded 16-bit timer/counters (TC2), and a programmable watchdog timer. Here's a general overview of an AT89S8253-24AU application circuit:

    1. Power Supply: Connect VCC to a 4.0-5.5V power supply and connect GND to the system ground. Put a decoupling capacitor (often 100nF) between VCC and GND as closely as you can.

    2. Reset Circuit: Connect a push-button switch to the RST pin for manual reset. Connect the RST pin on one end, and ground on the other. It's also good practice to add a pull-up resistor (10k ohm typical) between RST and VCC.

    3. Clock Circuit: Interconnect XTAL1 and XTAL2 with an external crystal oscillator. To stop the oscillation, connect two capacitors (typically 22pF) from each of these pins to ground.

    4. I/O Ports: The AT89S8253-24AU has three 8-bit I/O ports (Port 0, Port 2, and Port 3). Depending on your application, these can be interfaced with LEDs, switches, other ICs, etc.

    5. ISP (In-System Programming): For programming the flash memory, connect the MOSI, MISO, SCK, and RESET pins of your programmer to the corresponding pins on the AT89S8253-24AU.

    6. UART Interface: For serial communication, connect your device (like a computer or a GPS module) to the TxD and RxD pins on Port 3.

    7. External Memory Interface: If your application requires more memory, connect the address/data bus pins (Port 0 and Port 2) and control pins (RD, WR, ALE, PSEN) to your external memory.

    This is a basic application circuit and might need modifications based on the specific needs of your project. For a comprehensive understanding, refer to the AT89S8253-24AU datasheet and user manual. They will provide more detailed information including accurate component values and comprehensive design guidelines.
