GENERAL DESCRIPTION
The Z87100 Wireless Controller is a member of the Z8® single-chip microcontroller family and is manufactured in CMOS technology. Zilog’s CMOS Z87100 microcontroller offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
The Z87100 architecture is based on Zilog’s 8-bit microcontroller core with the addition of an Expanded Register File which allows access to register mapped peripheral and I/O circuits. The Z87100 offers a flexible I/O scheme and a number of ancillary features that are useful in many consumer, industrial, automotive, and advanced scientific applications.
