AT49BV002AT-70JI Product Details


The AT49BV002A(N)(T) is a 2.7-volt-only in-system reprogrammable Flash Memory. Its 2 megabits of memory is organized as 262,144 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 54 mW over the industrial temperature range. When the device is deselected, the CMOS standby current is less than 50 µA. For the AT49BV002AN(T) pin 1 for PLCC package and pin 9 for the TSOP package are no connect pins. To allow for simple in-system reprogrammability, the AT49BV002A(N)(T) does not require high input voltages for programming. Five-voltonly commands determine the read and programming operation of the device. Reading data out of the device is similar to reading from an EPROM; it has standard CE, OE, and WE inputs to avoid bus contention. Reprogramming the AT49BV002A(N)(T) is performed by erasing a block of data and then programming on a byte by byte basis. The byte programming time is a fast 30 µs. The end of a program cycle can be optionally detected by the DATA polling feature. Once the end of a byte program cycle has been detected, a new access for a read or program can begin. The typical number of program and erase cycles is in excess of 10,000 cycles.
