ST16C650A 2.90V TO 5.5V UART WITH 32-BYTE FIFO
The ST16C650A (650A) is a 2.90 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs. This device supports Intel and PC ISA mode data bus interfaces and is software compatible to industry standard 16C450, 16C550, and ST16C580 UARTs.
The 650A has 32 bytes of TX and RX FIFOs and is capable of operating up to serial data rates of 3.125 Mbps at 5 volt supply voltage. The internal registers include the 16C550 register set plus Exar’s enhanced registers for additional features to support today’s highly demanding data communication needs. The enhanced features include automatic hardware and software flow control, selectable TX and RX trigger levels, and wireless infrared (IrDA) encoder/decoder.
The device provides a new capability to give user the ability to program the wireless infrared encoder output pulse width, hence reducing the power consumption of a handheld unit.
The ST16C650A device comes in the 44-pin PLCC and 48-pin TQFP packages in both the commercial and industrial temperature ranges.
