The F81217 mainly provides 3 pure UART ports and one UART+ IR port through LPC. Each UART includes 16/32/64/128-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability and an interrupt system. Also support 8 GPIO, 4 sets of LED and 6 case open detection functions. One watch dog timer is provided for system controlling and the time interval can be programmed by register or hardware power on setting pin. One clock 24/48MHz input is necessary, and default is 24MHz. Powered by 3.3V voltage, the F81217 is in the small 64 pin TQFP package (7mm x 7mm).
