Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 67 mV 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. The AT49BV/LV4096A locates the boot block at lowest order addresses “bottom boot” . To allow for simple in-system reprogrammability, the AT49BV/LV4096A 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 AT49BV/LV4096A is performed by first erasing a block of data and then programming on a byte-by-byte or word-by-word basis. 4-megabit 512K x 8/ 256K x 16 Single 2.7-volt Battery-Voltage Flash Memory AT49BV4096A AT49LV4096A Pin Configurations Pin Name Function A0 - A17 Addresses Chip Enable Output Enable Write Enable RESET Reset VPP can be left unconnected or connected to VCC, GND, 5V or 12V.
