MCS® 51 Microcontroller Family, High Speed

Product Overview
The MCS® 51 high speed microcontrollers provide the current MCS 51 microcontroller product lines with increased frequency performances of up to 24 MHz and 33 MHz. For most MCS 51 customer designs that run at 12 MHz or 16 MHz today, performance can now be doubled with the new 24 MHz and 33 MHz versions. They are code and pin compatible with existing MCS 51 microcontrollers and therefore allow easy upgrade paths to all MCS 51 microcontroller applications that require a faster running part. The MCS 51 high speed microcontrollers bring you all the benefits you would expect from the original innovator of the MCS 51 microcontroller family.

The Intel MCS 51 high speed microcontrollers are based on the MCS 51 microcontroller architecture. They are code and pin compatible with the existing MCS 51 microcontrollers and therefore are direct "drop-in" replacements to existing MCS 51 microcontroller applications.

The MCS 51 high speed microcontrollers will make ideal performance upgrade paths for all existing MCS 51 microcontroller applications requiring increased frequency performance, such as CD-ROM drives, scanners, fax/modems, card readers, and etc.

The MCS 51 high speed microcontrollers offer customers an easy upgrade path to increased frequency performance required in MCS 51 microcontroller applications. This proliferation is an extension to the existing MCS 51 microcontroller family of products to allow embedded customers the ability to double the performance of their 12 MHz and 16 MHz applications. To achieve even higher performance, the new MCS® 251 microcontroller can provide customers with up to 5X per-formance on the same MCS 51 microcontroller code and up to 15X with the use of the new instruction set.
