Texas Instruments Inc has announced the TACT82S411, a new single chip implementation of all the support circuitry surrounding the CPU in an AT-alike, operating at up to 20MHz for 80286 and 80386SX laptops and notebooks: the new chip will integrate system logic and most peripheral functions, including interrupt controller, timer and real-time clock, so that only seven logic devices, as well as memory, processor and math co-processor are needed on a 80286 or 80386SX motherboard; the chip features 128-byte CMOS configuration RAM, two-way and four-way page interleave mode with 64Kb, 256Kb, 1Mb and 4Mb dynamic RAM, and support for up to 32Mb memory; sampling starts this month, with volume in the fourth quarter.
