APPENDIX A  A-1
The Intel microcontroller family now has three new
members: the Intel 8031, 8051, and 8751 single-chip
microcomputers. 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.
