Z86E0812PSG1866 Datasheet PDF - Zilog

The Z86E0812PSG1866 is an One-time programmable (OTP) 8-bit Microcontroller based on single-chip Z8® MCU family that allow easy software development, debug, prototyping and small production runs not economically desirable with masked ROM versions. For applications demanding powerful I/O capabilities, the dedicated input and output lines are grouped into three ports and are configurable under software control to provide timing, status signals or parallel I/O. Two on-chip counter/timers, with a large number of user selectable modes, offload the system of administering real-time tasks such as counting/timing and I/O data communications.

● 14 Input/Output lines

● Six vectored, prioritized interrupts (3 falling edge, 1 rising edge, 2 timers)

● Two analog comparators

● Low noise, ROM protect, Auto latch, Watch-dog timer, EPROM/Test mode disable

● Two programmable 8-bit counter/timers, each with 6-bit programmable prescaler

● Power-on reset (POR)

● On-chip oscillator that accepts XTAL, ceramic resonance, LC, RC or external clock

● Clock-free WDT reset

● Low-power consumption (50mw typical)

● Fast instruction pointer (1µs at 12MHz)
