GENERAL DESCRIPTION
●Zilog"s Z86E04/E08 Microcontrollers (MCU) are One-Time Programmable (OTP) members of Zilog’s 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 Z86E04/E08"s 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.
●FEATURES
●■ 14 Input/Output Lines
●■ Six Vectored, Prioritized Interrupts (3 falling edge, 1 rising edge, 2 timers)
●■ Two Analog Comparators
●■ Program Options:
● – Low Noise
● – ROM Protect
● – Auto Latch
● – Watch-Dog Timer (WDT)
● – EPROM/Test Mode Disable
●■ Two Programmable 8-Bit Counter/Timers, Each with 6-Bit Programmable Prescaler
●■ WDT/ Power-On Reset (POR)
●■ On-Chip Oscillator that Accepts XTAL, Ceramic Resonance, LC, RC, or External Clock
●■ Clock-Free WDT Reset
●■ Low-Power Consumption (50 mw typical)
●■ Fast Instruction Pointer (1µs @ 12 MHz)
●■ RAM Bytes (125)
