That sounds great; let's hope they follow with a LPC2126 for us
RAM-hungry types!

Curt,

it is my understanding that you can use the match registers without
changing the I/O pins but I will make sure this statement is true. In
regards to the number of I/O pins there is relief on the way. The
LPC2114 / LPC2124 is in a 64-pin package and offers additional GPIO
pins. According to my information the 2114 is very similar priced to
the LPC2104 but offers more I/O pins and a 4-channel 10-ADC as well as
a second SPI interface. For RAM intensive applications however, the
2105/2106 offer 32/64k RAM which is not an option for the 64-pin device.
Overall it seems that Philips is serious with the slogan "Let's make
things better" ;-)
