描述
The ST16C650A1 is a universal asynchronous receiver and transmitter (UART) and is pin compatible with the ST16C550 UART. The 650A is an enhanced UART with 32 byte FIFO’s, automatic hardware/software flow control, and data rates up to 1.5Mbps. Onboard status registers provide the user with error indications and operational status. Modem interface control is included and can be optionally configured to operate with the Infrared (IrDA) encoder/ decoder.

The system interrupts may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics. The 650A is available in 40 pin PDIP, 44 pin PLCC, and 48 pin TQFP packages. The 40 pin package does not offer the PC mode. The 44 and 48 pin versions provide both the standard (STD) mode or PC ISA bus (PC) mode. The STD mode is compatible with the ST16C450 and ST16C550 while the PC mode allows connection to the PC ISA bus.

NOTE: 1 Covered by US Patent #5,649,122.
