GENERAL DESCRIPTION

The Z80189/Z8L189 are cost-effective modem controllers

that address a new generation of data pumps having the

HDLC formatting feature. Data pumps of these types do

not require an HDLC interface; therefore, the Z80189 does

not need the ESCC^™. The addition of the PC DMA Mailbox

RegistersallowDMAdatatransferbetweenthePCmemory

andthemodemspeaker/microphoneCODEC.TheZ80189

is a smart peripheral controller chip for modem (in particu-

lar V.34 applications), fax, voice messaging, and other

communications applications.

TheintegrationofCOMPortDecodecircuitrytotheZ80189

allows the MIMIC to be selected for a specific COM Port

Address (PC COM Port Address 1-4). COM Port Decode

circuitry is simplified by allowing the user to select the

MIMIC COM Port addresses through software, in addition

to eliminating the need for external circuitry required for

COM Port Decode logic.

The PC DMA and I/O Mailbox Interface can be used to

provide communication paths between the PC Host and

theZ80189. Thesenewcommunicationpathscanbeused

for voice, DTAD, or jumperless COM Port selection.

The Z80189/Z8L189 consists of an enhanced Z8S180

microprocessor, a 16550 MIMIC with increased MIMIC

drivecapability fordirectconnectiontotheIBMPC, XT, AT

bus, and 24 bits of parallel I/O. Current PC modem soft-

ware compatibility can be maintained with the Z80189's

ability to mimic the 16550 UART chip. The Z80180 core is

the intelligent controller between the data pump and

16550 MIMIC interface when used in internal applications.

This intelligent controller performs the data compression

and error correction on outgoing and incoming data.

Notes:

All Signals with a preceding front slash, "/", are active Low, e.g.:

B//W (WORD is active Low); /B/W (BYTE is active Low, only).
