### **Descriptions:**  
The **SAB80C515A-N18-T3** is an enhanced 80C51 microcontroller with extended features for industrial and embedded applications. It includes a built-in watchdog timer, power-saving modes (idle and power-down), and supports external memory expansion.  

### **Features:**  
- **80C51 Core:** Fully compatible with the MCS-51 instruction set.  
- **On-Chip ROM:** 16 KB for program storage.  
- **Extended RAM:** 512 bytes for data storage.  
- **Three 16-bit Timers:** For timing and event counting.  
- **Serial Port (UART):** Full-duplex communication.  
- **Power Management:** Idle and power-down modes for low-power operation.  
- **Watchdog Timer:** For system reliability.  
- **PLCC-44 Package:** Suitable for surface-mount applications.  

This microcontroller is commonly used in industrial control, automotive, and embedded systems requiring 80C51 compatibility.

Application Scenarios & Design Considerations

8-Bit CMOS Single-Chip Microcontroller

Alternative Part Number

  • N80C515A --: Original 80C515 microcontroller from Intel with compatible 8051 core, same 18 MHz speed grade, and pin-compatible PLCC package; the SAB80C515A is a licensed second-source of this device.
  • P80C515A --: NXP (formerly Philips) 80C515A variant with identical 8051 architecture, 18 MHz operation, and same peripheral set; a well-established drop-in replacement for the Infineon SAB80C515A.
  • TMP80C515A --: Toshiba second-source 80C515A microcontroller with matching 8051 core, 18 MHz speed, and compatible pinout; suitable as a functional equivalent when the Infineon part is unavailable.
