Descriptions

The GM16C550 is an asynchronous communications element (ACE) that is functionally equivalent to the GM16C450, and addition-ally incorporates a 16byte FIFOs are available on both the transmitter and receiver, and can be activated by placing the device in the FIFO mode. After a reset, the registers of the GM16C550 are identical to those of the GM16C450.

Features

● Fully compatible with GM16C450.

● Modem controm signals include CTS , RTS , DSR , DTR , RI and -DCD .

● Programmable serial characteristics:

—5-, 6-, 7- or 8-bit characters

— Even-, odd-, or no-parity bit generation and detection

—1-, 11/2- or 2-stop bit generation

— Baud rate generation (DC to 256K baud)

● 16 byte FIFO reduces CPU interrupts.

● Independent control of transmit, receive, line status, data set interrupts, FIFOs.

● Full status reporting capabilities

● Three-state, TTL drive capabilities for biderectional data bus and control bus.

● 40DIP/44PLCC
