ATtiny13A vs. ATtiny13

A-grade AVRs are minor improvements over the previous iteration; these improvements vary from chip to chip, e.g. the difference between ATtiny2313 and ATtiny2313A is different from the difference between ATmega128 and ATmega128A.

To be more specific, the ATtiny13 is the original version and uses a different process technology than the ATtiny13A. The A-suffixed parts are fabricated with a low power process marketed as "picoPower", and the main difference is that they generally consume less power at the same voltage and frequency.

ATtiny13 vs.ATtiny13A.jpg

ATtiny13 vs.ATtiny13A

Regarding differences from the point of view of code compatibility, I see no reason why the ATtiny13A would not be code and binary compatible with programs written for the ATtiny13. However, the reverse is not strictly the case: While the instruction sets and most peripherals are identical, the ATtiny13A has the extra registers PRR (Power Reduction Register) and BODCR (Brown-Out Detector Control Register).
