Description

The AT49BV004(T) and AT49BV4096A(T) are 3-volt, 4-megabit Flash Memories

organized as 524,288 words of 8 bits each or 256K words of 16 bits each. Manufac-

tured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access

times to 120 ns with power dissipation of just 67 mW at 2.7V read. When deselected,

the CMOS standby current is less than 50 µA.

AT49BV004

The device contains a user-enabled “boot block” protection feature. Two versions of

the feature are available: the AT49BV004/4096A locates the boot block at lowest

order addresses (“bottom boot”); the AT49BV004T/4096AT locates it at highest order

addresses (“top boot”).

Preliminary

To allow for simple in-system reprogrammability, the AT49BV004(T)/4096A(T) does

not require high input voltages for programming. 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 AT49BV004(T)/4096A(T) is performed by first

erasing a block of data and then programming on a byte-by-byte or word-by-word

basis.
