MAB 8031AH-12P 8-bit Single Chip Microcontroller DIP-40 IC
The MAB 8031AH-12P is a high-performance, 8-bit microcontroller from Philips Semiconductors. It is based on N-channel silicon-gate MOS technology and is part of the MAB8031AH family. This model, marked with the ‘A’ suffix, is a ROM-less version, meaning it does not have built-in program memory. It supports up to 64KB of external program memory and 64KB of external data memory using standard TTL-compatible memory chips. The ’12P’ indicates it operates at a frequency of 12MHz and comes in a plastic Dual In-Line Package (DIP-40). The microcontroller operates within a temperature range of 0°C to +70°C.
Features:
- High-performance, ROM-less 8-bit microcontroller.
- Industry-standard 8051 architecture.
- Operating frequency of 12MHz (as per title designation).
- On-chip 128×8 RAM.
- 32 I/O lines across four 8-bit ports.
- Two 16-bit timer/event counters.
- High-performance full-duplex serial channel.
