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 XR16C850 is available in 40 pin PDIP, 44 pin PLCC, 48 TQFP, and 52 pin QFP packages. The 40 pin package does not offer the PC mode. The 44, 48, and 52 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.
