The ST16C650A1 (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, ST16C580 and ST16C650A UARTs. The 650A has 32 bytes of TX and RX FIFOs and is capable of operating up to .
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. NOTE: 1 Covered by US patents #5,649,122. FEATURES Added features in .
