5 µs @ 4 MHz ESD Protection Circuitry s s GENERAL DESCRIPTION The Z86318 is a member of the Z8® MCU family of CMOS 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.
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 effici...
