* Under development, available in 3Q, 2010.
Note: 1.Part number which include a "U" have an internal UART function; part numbers which include a "B" have a USB interface.
2.All devices include a fully integrated RC system oscillator.
3.Four I/O lines on each device can be configured as software LCD COM driver pins. |
