MCS® 251 microcontroller line gets richer, better
Intel recently introduced three new products from the MCS® 251 microcontroller family: the 8xC251SA, 8xC251SP and 8xC251SQ. Based on the high-performance MCS® 251 microcontroller architecture, all provide significant performance improvements over MCS® 51 microcontroller architecture, more RAM and ROM memory options, and new price options. They represent the easiest way to upgrade performance of existing MCS 51 microcontroller applications, delivering up to 15 times the performance.
The 8xC251SA, SP and SQ share the MCS 251 controller's advanced register-based CPU architecture and also have pipelined instruction execution units. They use the powerful MCS 251 microcontroller instruction set, with many enhanced 8-, 16- and 32-bit instructions available. They also execute C code efficiently. Most importantly, the 8xC251SA, SP and SQ are binary code and pin-compatible with existing MCS 51 microcontrollers.
Flexible RAM, ROM/EPROM and PricingThe new MCS 251 microcontrollers range in price from $5.50 to $6.50 in 100K unit direct OEM pricing for ROM products. All are available as standard 5V 16 MHz parts and are available in commercial as well as extended temperature range. Product options are:
8xC251SA—8K ROM/OTPROM and 1K RAM
8xC251SB—16K ROM/OTPROM and 1K RAM
8xC251SP—8K ROM/OTPROM and 512K RAM
8xC251SQ—16K ROM/OTPROM and 512K RAM
Romless versions are also available
PackagingThe 8xC251 microcontrollers are available in 40-pin PDIP and 44-pin PLCC packages. Fast, Easy Development
Intel and its third party vendors offer a variety of hardware and software development tools to make your MCS 251 controller development as fast as possible. Intel's ApBUILDER interactive programming software shortens your learning curve, reduces your total design time, and speeds your migration to the MCS 251 architecture. 8XC251SA, 8XC251SB, 8XC251SP, 8XC251SQ Embedded Microcontroller User's Manual (.pdf 3,118,443 bytes)
