AT49BV322D-70CU-H

The AT49BV322D-70CU-H is one member of the AT49BV322D series.The AT49BV322D is a 2.7-volt 32-megabit Flash memory organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package. AT49BV322D-70CU-H has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it ideally suited for in-system programming.

Features of the AT49BV322D-70CU-H are:(1)single voltage read/write operation: 2.65V to 3.6V; (2)access time70 ns; (3)fast word program time10 s; (4)fast sector erase time100 ms; (5)sector lockdown support; (6)TSOP and CBGA package options; (7)top or bottom boot block configuration available; (8)128-bit protection register; (9)minimum 100,000 erase cycles; (10)common flash interface (CFI); (11)VPP pin for write protection and accelerated program operation .

The absolute maximum ratings of the AT49BV322D-70CU-H can be summarized as:(1)all input voltages(including NC pins) with respect to ground:-0.6 to 6.25V;(2)temperature under bias:-55 to 125;(3)storage temperature:-65 to 150;(4)all output voltages with respect to ground:-0.6 to Vcc+0.6V;(5)voltage on Vpp with respect to ground:-0.6 to +9.5V.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
