Fast applications), fax, voice messaging and other communications applications. It uses the Z80180 microprocessor (Z8S180 MPU core) linked with two channels of the industry standard Z85230 ESCC (Enhanced Serial Communications Controller), 24 bits of parallel I/O, and a 16550 MIMIC for direct connection to the IBM PC, XT, AT bus. The Z80182/Z8L182 allows complete flexibility for both internal PC and external applications. Also current PC modem software compatibility can be maintained with the Z80182/Z8L182 ability to mimic the 16550 UART chip. The Z80180 acts as an interface between the ESCC™ and ...
