Hello - We are using the CODEC (TLV320AIC3120) in a battery powered product consisting of the CODEC, microphone, speaker and host processor. We would like to use the ATTINY84 has the host processor and I would like to know if this processor would be sufficient or if there is another AVR processor you would recommend. If there is a set of minimum requirements for the host processor, that would be very helpful. Thank you, Chris
