OK, here's a problem I had with the Appnote AVR335 (Digital Voice Recorder using an AT90S8535 and a AT45DB161). The circuit given shows the same Vcc being given to both the DataFlash and the AVR, even though the AVR is a 5V part and the DataFlash is a 2.7V only part. What gives? Does the DataFlash have 5V tolerant I/Os? Please help!
