Features
Description
The AT49BV008A(T) and AT49BV8192A(T) are 3-volt, 8-megabit Flash memories
organized as 1,048,576 words of 8 bits each or 512K words of 16 bits each. Manufac-
tured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access
times to 90 ns with power dissipation of just 67 mW at 2.7V read. When deselected,
the CMOS standby current is less than 50 µA.
The device contains a user-enabled “boot block” protection feature. Two versions of
the feature are available: the AT49BV008A/8192A locates the boot block at lowest
order addresses (“bottom boot”); the AT49BV008AT/8192AT locates it at highest
order addresses (“top boot”).
To allow for simple in-system reprogrammability, the AT49BV008A(T)/8192A(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
