Product Overview
Intel P8052AH-BASIC 8-bit microcontroller in a 40-pin plastic dual in-line package (DIP-40). This MCS-51 architecture chip contains a factory mask-programmed 8 KB ROM containing the Intel BASIC-52 interpreter (Version 1.1), 256 bytes of internal RAM, 32 programmable I/O lines across four 8-bit ports, three 16-bit timer/counters, and an integrated full-duplex UART serial port.

Applications
- Restoring or maintaining legacy MCS-51 industrial control systems and single-board computers
- Building standalone 8052 retrocomputing development boards running the embedded BASIC-52 interpreter directly over a serial terminal
- Replacing failed microcontrollers in vintage laboratory instrumentation and automated test fixtures
- Prototyping embedded hardware experiments without requiring an external cross-compiler or dedicated programmer
Frequently Asked Questions
Does this microcontroller require an external EPROM to run BASIC code?
No. The Intel BASIC-52 interpreter is factory mask-programmed directly into the chip's internal 8 KB ROM. It boots straight to the interactive BASIC interpreter over its serial UART upon reset.
What package format is this component?
This unit is housed in a standard 40-pin dual in-line package (DIP-40) for through-hole mounting or socket installation.
Why buy this specific pull over unverified surplus lots?
You receive the exact Intel P8052AH-BASIC DIP-40 microcontroller shown in the photos, with intact pins and crisp Version 1.1 markings clearly documented. Orders leave our Idaho warehouse the same or next business day.
Plug in a serial terminal, hit reset, and take full control with classic embedded BASIC without needing an external compiler. For retrocomputing builds and industrial system upkeep, this vintage Intel silicon delivers original 8052 execution right out of the socket.
