73K222AU General Description

  The 73K222AU is a compact, high-performance modem which includes a 8250A/16C450 compatible UART with the 1200 bit/s modem function on a single chip. Based on the 73K222L 5V low power CMOS modem IC, the 73K222AU is the perfect modem/UART component for integral modem applications. It is ideal for applications such as portable terminals and laptop computers.

  The 73K222AU is the first fully featured modem IC which can function as an intelligent modem in integral applications without requiring a separate dedicated microcontroller. It provides for data communication at 1200, 600, and 300 bit/s in a multi-mode manner that allows operation compatible with both Bell 212A/103 and CCITT V.22/V.21 standards. The digital interface section contains a high speed version of the industry standard 8250A/16C450 UART, commonly used in personal computer products. A unique feature of the 73K222AU is that the UART section can be used without the modem function, providing an additional asynchronous port at no added cost. The 73K222AU is designed in CMOS technology and operates from a single +5V supply. Available packaging includes 40-pin DIP or 44-pin PLCC for surface mount applications.
