F81216AD
1. General Description
The F81216AD mainly provides 3 pure UART ports and one UART+ IR port through
LPC.
Each UART includes 16-byte send/receive FIFO, a programmable baud rate
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 F81216AD is in the small
48pin LQFP package (7mm x 7mm).
generator, complete modem control capability and an interrupt system.
