We use the LPC2103 microcontroller in our system. Our system currently requires several AD inputs as well as the digital communication pins. Is there a viable replacement available that would meet our needs as well as provide more memory? Ideally, it would have the same package size, number of inputs and communication channels. I have searched the online parts listing and the other members of the LPC family don't seem to offer the needed specifications. Thank you for your help as we work on upgrading our product!
