Intel Corporation Integrated Circuits (ICs) - Embedded - Microcontrollers P80C151SB16

The P80C151SB16 is a high-performance CHMOS microcontroller compatible with the MCS¬Æ 51 instruction set. It features a 16 MHz operating frequency and is available in both 40-pin PDIP and 44-lead PLCC packages. The device includes 256 bytes of on-chip RAM and offers options for 8 Kbytes or 16 Kbytes of on-chip ROM/OTPROM, or can be used without any ROM. This microcontroller supports a variety of user-selectable configurations, including external wait states and page mode, and provides a 64K external code and data memory space. It includes 32 programmable I/O lines, seven maskable interrupt sources with four programmable priority levels, and three flexible 16-bit timer/counters. Additionally, it features a hardware watchdog timer and a programmable serial I/O port with automatic address recognition. The operating temperature range for the commercial version is 0¬8C to 70¬8C, while the express version operates from -40¬8C to 85¬8C. The P80C151SB16 is suitable for applications requiring robust performance and flexibility in microcontroller design.
