P8052AH** is a microcontroller manufactured by **Intel**.

The P8052AH is a microcontroller manufactured by Intel. Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: Intel
  • Part Number: P8052AH
  • Core Architecture: 8-bit
  • CPU: 8051-based
  • Clock Speed: Up to 12 MHz
  • Program Memory (ROM): 8 KB (mask-programmed)
  • RAM: 256 bytes
  • I/O Ports: Four 8-bit ports (P0, P1, P2, P3)
  • Timers/Counters: Three 16-bit timers (Timer 0, Timer 1, Timer 2)
  • Serial Communication: UART (full-duplex)
  • Interrupts: Six interrupt sources with two priority levels
  • Power Supply: 5V ±10%
  • Operating Temperature: Commercial (0°C to 70°C)
  • Package: 40-pin DIP (Dual In-line Package)

Descriptions:

  • The P8052AH is an enhanced version of the Intel 8051 microcontroller with additional features, including an extra timer (Timer 2) and expanded memory.
  • It is a mask-ROM variant, meaning the program memory is factory-programmed and not user-erasable.
  • Suitable for embedded control applications requiring a robust and reliable 8-bit microcontroller.

Features:

  • Enhanced 8051 Core: Fully compatible with the 8051 instruction set.
  • Extended Timer (Timer 2): Provides additional functionality for PWM, capture, and baud rate generation.
  • On-Chip UART: Supports serial communication (RS-232, RS-485).
  • Multiple Interrupt Sources: Six interrupt vectors for efficient event handling.
  • Low EMI Emission: Designed for noise-sensitive applications.
  • Wide Operating Voltage: 5V ±10% tolerance.

This microcontroller was widely used in industrial control, automation, and consumer electronics before newer flash-based variants became prevalent.
