DESCRIPTION
The ST7554 is a single chip host signal processing
Modem/fax/voice controller that supports data rates
up to 56Kbps. All data pump and protocol functions
are executed on the host PC’s processor. This
product has been developed in cooperation with
Smart Link Ltd, who ported "USB-Modio", its host
based Modem and system software into ST system
and hardware platform. The ST7554 directly con-
nects to ST high performance Modem analog front-
end (MAFE) STLC7550 or to the highly integrated
MAFE+DAA chip-set ST75951/ST952. The ST7554
also features an Universal Serial Bus (USB) inter-
face for direct connection to the host PC for maxi-
mum flexibility and real plug & play operation.
