Interfacing a microphone using ATTiny26 for ADC to DAC

[leoren_tm]

i have a project on interfacing a microphone, il be using ATTiny26 for ADC to DAC(digital to analog) conversion..
pls help me find specs for this....and i have a copy of a C++ source code for this, is there any availble in hir??
thx in advnce....

and also spec on Motorola ColdFire MCF5272
and the Snapgear SecureEdge 1100 unit

adc attiny26

Please take a look at https://www.avrfreaks.net/, there many AVR project complete with schematic and source code

attiny26 adc

can you give the specs and pin asing for the microntroller??
pls

Added after 10 minutes:

attiny26 timer

can you give the specs and pin asing for the microntroller??

Which one?
Only ATTiny26
http://www.atmel.com/dyn/products/product_card.asp?part_id=2967
or whole Atmel AVR family?

AVR(automatic voltage regulator?)

AVR mean nothing, just AVR! No body know it but Atmel.
