ST16C2450 - (ST16C2450 / ST16C2451) 2.97V TO 5.5V DUART

General Description

The ST16C2450 (2450) is a dual universal asynchronous receiver and transmitter (UART).

The ST16C2450 is an improved version of the ST16C2450 with lower operating voltage and 5 volt tolerant inputs.

The 2450 provides enhanced UART functions, a modem control interface and data rates up to 1.5 Mbps.

áç SEPTEMBER 2003 ST16C2450 2.97V TO 5.5V DUART REV. 4.0.0 GENERAL DESCRIPTION The ST16C2450 (2450) is a dual universal asynchronous receiver and transmitter (UART). The ST16C2450 is an improved version of the ST16C2450 with lower operating voltage and 5 volt tolerant inputs. The 2450 provides enhanced UART functions, a modem control interface and data rates up to 1.5 Mbps. Onboard status registers provide the user with error indications and operational status. Independent programmable baud rate generators are provided to select transmit and receive clock rates up to 1.5 Mbps. An internal loopback capability allows onboard diagnostics. The 2450 is available in a 44pin PLCC and 48-pin TQFP packages. The 2450 is fabricated in an advanced CMOS process capable of operating from 2.
