Intel's 8-bit MCS® 51 family of microcontrollers is a leading choice for embedded control. This Classic family consists of CHMOS versions of all the original 8-bit microcontrollers that introduced the MCS 51 microcontroller family. Intel offers a wide variety of on-board memory in EPROM, ROM and OTP, as well as CPU-only microcontrollers. Intel's proven CHMOS technology provides lower power, higher integration and higher performance.
On-chip peripherals (timer/counters, serial ports, PCA, etc.)
High integration. Enables low-cost and I/O ports, low-chip count designs

These products are now offered with frequencies of up to 24 MHz @ 20% Vcc and 33 MHz @ 10% Vcc. Packages include 44Ld PLCC, 44Ld QFP, 40Ld P-Dip and 40Ld CerDip.
The new offerings are specially designed to accommodate increased
frequency performance required in MCS 51 microcontroller applications.
All products mentioned above are available at the lower speed of 16Mhz as well.
Wafer Program
Another benefit you have with these products is that they are now available in wafer form. If you are in need of bare die or the product in a package that Intel does not offer, then your solution is to purchase wafers.
