33 MIPSの8051マイクロコントローラ、アプリケーション内でプログラマブルなフラッシュメモリを提供
DALLAS, TX—October 17, 2003—Dallas Semiconductor (NASDAQ: MXIM) introduces its latest ultra-high-speed microcontrollers, the DS89C430, DS89C440, and DS89C450. At one clock-per-machine cycle, these microcontrollers can achieve up to 33 MIPS, making the DS89C430 the fastest drop-in 8051 microcontroller available on the market. In addition, the DS89C430, DS89C440, and DS89C450 integrate 16kB, 32kB, and 64kB flash memories, respectively.
Available in 40-pin DIP, 44-pin PLCC, and 44-pin TQFP packages, the DS89C430/DS89C440/DS89C450 are pin and code compatible with the original 8051. Standard features include two full-duplex UARTs, 13 interrupt sources with five priority levels, variable length MOVX timing, programmable watchdog timer, and power-fail reset. Additional performance improvements include dual data pointers with auto increment/decrement that enable developers to quickly move data at rates in excess of 2Mbps.
Prices start at $7.00 (1000-up, FOB USA) with samples available now. For more information about the family of microcontrollers, contact any Maxim sales representative or visit http://www.maxim-ic.com/mcu.
