Thanks to all who answered my question, I will search for Atmel products... Just to let you know, the idea that I want to develop is based on a 16F877 for voice recording and playing (with PWM), based on a CDPCM data compression. This way sampling voice at 8kHz, 16 bit (that will take 16kbyte/sec), is reduced at 4kbyte/sec; so a 4Mbit flash will give about 130sec of speech... more that enough!! Thanks again and good work!!
