Serial Flash Chip Shows Sub-90 nm Device Compatibility
Exhibiting an operating voltage range from 1.65 V to 1.95 V, Atmel’s AT25DF081 8 Mb Serial Flash chip operates in the same voltage range as sub-90 nm ASICs and processors/controllers, yielding a single supply voltage for all system components. The device stores program code and data in battery-powered portable consumer products including personal media players and smartphones while operating at 66 MHz. The component enables an application to shadow the contents of the memory in 130 ms, and eliminates the need for an additional LDO and level shifters on control and data lines. The chip offers 8-lead 150-mil wide “narrow body” SOIC, 8-contact 5 mm × 6 mm × 0.60 mm UDFN or 0.40 mm thin 11-ball dBGA packaging options. Pricing starts at $0.66, $0.70 and $0.83 each, respectively, in 10,000 quantities.
