GENERAL DESCRIPTION
The Z86217/C17 are members of Zilog's Z8® family of
microcontrollers designed to reduce external system com-
ponents and offer easy software/hardware development
tools for pointing device and trackball applications.
The devices feature on-board pull-up resistors, and a
scalable trip-point buffer to accommodate opto-transistor
outputs. The high drive ports are capable of up to 20 mA
(at VOL = 0.8-volt) current sinking per pin, with three pins
maximum, providing extra sinking current capability.
The Z86217/C17's permanently enabled Watch-Dog Timer
(WDT) operates upon power-up of the MCU, and provides
added operational reliability for pointing device and
trackball environments.
An oscillator filter assists in separating out high-frequency
noise from the oscillator input pin.
Two on-chip counter/timers with a large number of
selectable modes, offload the system of administering
real-time tasks such as counting/timing and I/O data
communications.
Notes:
Refer to the DC electrical characteristics for detailed specification of the
sinking current.
On the Z86C17, P24-P27 has a 20K pull-up, and P32 has a 47K pull-
down. The Z86217 does not have these functions.
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:
