That information is not entirely correct.<br><br>The NXP TEA5766 has FM, RDS, and I2C. It can be implemented in a 36 mm square area with only 11 external components (other than the IC). It Operates at 2.7V, 15mA, and consumes
40.5 mW. The size of the IC itself is 3.3x3.3mm.<br><br>Sounds appealing, doesn't it?<br><br>Brad<br><br><div><span class="gmail_quote">On 8/23/07, <b class="gmail_sendername">Ian Stirling</b> <<a href="mailto:OpenMoko@mauve.plus.com">
