Special Environment Product Overview Intel's controllers have smooth upgrade paths and extensive on-chip integration. Intel continues to produce leading edge controllers and offers these products over the rugged temperature grades required of today's demanding industries. Architecture Overview Intel's 8-bit MCS® 51 microcontroller family consists of CHMOS versions of the original 8-bit microcontrollers. The MCS 51 microcontroller architecture is optimized for control-oriented applications. A variety of fast addressing modes for accessing the internal RAM facilitates byte processing and numerical operations on small data structures. The instruction set provides a convenient menu of 8-bit arithmetic instructions, including multiply and divide instructions. Extensive on-chip support is provided for 1-bit variables as a separate data type, allowing direct bit manipulation and testing in control and logic systems that require Boolean processing. Intel offers a wide variety of MCS 51 controllers with different levels of on-chip peripherals and memory. The MCS 51 microcontroller family includes versions with on-chip EPROM, One-Time Programmable (OTP) and ROM memory, as well as CPU-only microcontrollers. Intel's proven CHMOS technology provides lower power, higher integration and higher performance in this line of controllers. FEATURES BENEFITS 8-bit CPU optimized for event control Efficient.
