Z8673316PSC Datasheet



The Z86E33/733/E34/E43/743/E44 8-bit CMOS One-Time Programmable (OTP) microcontrollers are members of Zilogs Z8® single-chip microcontroller family featuring enhanced wake-up circuitry, programmable Watch-Dog Timers, Low Noise EMI options, and easy hardware/software system expansion capability.
Four basic address spaces support a wide range of memory configurations. The designer has easy access to register mapped peripheral and I/O circuits.
For applications demanding powerful I/O capabilities, the Z86E33/733/E34 have 24 pins and the Z86E43/743/E44 have 32 pins of dedicated input and output. These lines are grouped into four ports, eight lines per port, and are configurable under software control to provide timing, status signals, and parallel I/O with or without handshake, and address/data bus for interfacing external memory.
