SAB 8052B-P Single-Chip Microcontroller IC 8Bit PDIP-40
The SAB 8052B-P is a high-performance 8-bit single-chip microcontroller, a member of the SAB 8052/8032 family. It is fabricated in an advanced N-channel, silicon-gate Siemens MYMOS technology, and it comes in a 40-pin plastic dual-in-line package (P-DIP-40). This microcontroller is fully backward compatible with the SAB 8051/8031, providing a seamless upgrade path with enhanced features. It integrates an 8Kx8 ROM, 256×8 RAM, 32 I/O lines, three 16-bit timers, and a full-duplex serial channel. It is a powerful and cost-effective solution for a wide range of applications that require up to 64 Kbytes of program and data memory.
The Siemens SAB8052B-P is an 8-bit microcontroller from Siemens’ SAB8050 family, fully compatible with the MCS-51 instruction set. Designed for embedded control applications, this device combines on-board program memory (ROM), data memory (RAM), timer/counters, programmable I/O ports, and full serial I/O support in a single PDIP-40 IC. Exceptional instruction throughput and flexible peripherals make it suitable for industrial control, consumer electronics, communication interfaces, and intelligent peripherals. The architecture supports complex control algorithms while maintaining low power consumption and ease of programming.
