Z80195

Notes:
Voltage on all pins with respect to GND. Permanent LSI damage may occur if maximum ratings are exceeded. Normal operation should be recommended operating conditions. If these conditions are exceeded, it could affect reliability of LSI.

The Z80185 and Z80195 are smart peripheral controller devices designed for general data communications applications, and architected specifically to accommodate all input and output (I/O) requirements for serial and parallel connectivity. Combining a high-performance CPU core with a variety of system and I/O resources, the Z80185/195 are useful in a broad range of applications. The Z80195 is the ROMless version of the device.

The Z80185 and Z80195 feature an enhanced Z8S180 microprocessor linked with one enhanced channel of the Z85230 ESCC™ serial communications controller, and 25 bits of parallel I/O, allowing software code compatibility with existing software code.

Seventeen lines can be configured as bidirectional Centronics (IEEE 1284) controllers. When configured as a 1284 controller, an I/O line can operate in either the host or peripheral role in compatible, nibble, byte or ECP mode. In addition, the Z80185 includes 32 Kbytes of on-chip ROM.These Z80185 and Z80195  devices are well-suited for external modems using a parallel interface, protocol translators, and cost-effective WAN adapters. The Z80185 and Z80195  is ideal for handling all laser printer I/O, as well as the main processor in costeffective printer applications.
