The F81216H mainly provides 3 pure UART ports and one UART+ IR port through LPC. Each UART includes 128-byte send/receive FIFO, a programmable baud rate generator, complete modem control capability and an interrupt system. |
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 F81216H is in the small 48 pin LQFP package (7mm x 7mm).
