5-Volt Operating Range 0°C to 70°C Operating Temperature Range GENERAL DESCRIPTION The Z86217/C17 are members of Zilog's Z8® family of microcontrollers designed to reduce external system components 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 pulldown.
The Z86217 does not have these functions.
All Signals with a preceding front slash, "/", are active Low, e.
