GENERAL DESCRIPTION

The Z86116 Wireless Controller is a member of the Z8® single-chip microcontroller family based on Zilog’s 8-bit microcontroller core. The Z86116 is designed with specific features for wireless spread spectrum applications using direct sequence pseudo-noise (PN) modulation.

Three address spaces, the Program Memory, Register File, and Expanded Register File (ERF), support a wide range of memory configurations. Through the ERF, the designer has access to three additional control registers that provide extra peripheral devices, I/O ports, and register addresses.

For applications demanding powerful I/O capabilities, the Z86116s dedicated input and output lines are grouped into two ports, and are configurable under software control to provide timing, status signals, or parallel I/O.
