TI MSP430 Microcontroller

TI is introcucing a series of msp430 variants with on board 12-bit AtoD, 8K to 60K of flash memory, on board reference, an analog comparator, hardware multiplier, two serial ports and 2 16-bit pwm timers. Believe it or not, the 8K version will sell for $2.95 @ qty 1k. That's not bad for *anything* with 64 pins let alone a 16 bit core micro.
