Product Summary
The AT49BV040B-JU is an in-system reprogrammable Flash Memory. Its 4 megabits of memory is organized as 524,288 words by 8 bits. The AT49BV040B-JU offers an access time of 70 ns (VCC = 2.7V to 3.6V) and an access time of 55 ns (VCC = 4.5V to 5.5V). The power dissipation over the industrial temperature range with VCC = 2.7V to 3.6V is 72mW and is 110mW with VCC = 4.5V to 5.5V. When the device is deselected, the CMOS standby current is less than 30μA. To allow for simple in-system reprogrammability, the AT49BV040B-JU does not require high input voltages for programming.
