Fonctionnalités et applications

The XR16C2852 (2852) is a dual universal asynchronous receiver and transmitter (UART). The 2852 provides enhanced UART functions with 128 byte FIFO, automatic RS-485 half duplex control, a modem control interface, and data rates up to 1.5 Mbps. Onboard status registers provide the user with error indications and operational status. An alternate function register supports concurrent write to UART A and B. System interrupts and modem control features may be tailored by external software to meet specific user requirements.

An internal loopback capability allows onboard diagnostics. Independent programmable baud rate generators are provided to select transmit and receive clock rates up to 1.5 Mbps. The baud rate generator can be configured for either crystal or external clock input. The 2852 is available in a 44-pin PLCC package and functionally compatible with the ST16C2552. The 2852 is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements.
