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.
■ Watch-Dog Timer (WDT)/Power-On Reset (POR)
■ On-Chip Oscillator that Accepts a RC, or External
Clock Drive
■ Low-Voltage Protection / Low-EMI Option
®
For applications demanding powerful I/O capabilities, the
Z86116's 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.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
Power connections follow conventional descriptions below:
