These devices, shown in Figure 1, will allow whole new classes of products to benefit from recent advances in Integrated Electronics. Thanks to Intel's new HMOS technology, they provide larger program and data memory spaces, more flexible I/O and peripheral capabilities, greater speed, and lower system cost than any previous-generation single-chip microcomputer.
