GENERAL DESCRIPTION

The Z86318 is a member of the Z8 microcontrollers. This device offers on-board pull-up and pull-down resistors (ROM mask-option programmable on a nibble basis), a scalable trip-point buffer to accommodate opto-transistor outputs, and high drive ports capable of up to 20 mA current sinking per pin (3 pins maximum).

The Z86318 features I/O Ports (IOL = 20 mA at VOL =

0.8V, 3 pins max.) to provide increased current sinking capabilities. These devices also offer users a selection of ROM mask options, which include a permanently enabled Watch-Dog Timer that ensures operational reliability across a broad range of application environments.

For applications requiring powerful I/O capabilities, the Z86318 provides dedicated input and output lines that are grouped into three ports. These ports can be configured by means of ROM mask options (nibble-programmable) as pull ups, pull downs, or neither. There are two basic address spaces available. Program Memory, and 124 bytes of general-purpose registers.

ESD Protection Circuitry

The Z86318 devices provide two on-chip 8-bit programmable counter/timers with a large number of user-selectable modes. Each counter/timer is driven by its own 6-bit programmable prescaler. The Z86318 counter/timers off-load system real-time tasks such as counting/timing and input/output data communications for increased system efficiency.

Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; operation of the device at any condition above those indicated in the operational sections of these specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
