DescriptionThe AT49BV320DT-70TU is one member of the AT49BV320DT series.The AT49BV320DT is a 2.7-volt 32-megabit Flash memory organized as 2,097,152 words of 16 bits each. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP package and a 47-ball CBGA package. The device 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 AT49BV320DT-70TU 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)VPP pin for write protection and accelerated program operation; (6)WP pin for sector protection; (7)RESET input for device initialization; (8)flexible sector protection; (9)TSOP and CBGA package options; (10)top or bottom boot block configuration available; (11)128-bit protection register; (12)minimum 100,000 erase cycles; (13)common flash interface (CFI); (14)green (Pb/Halide-free) packaging.
The absolute maximum ratings of the AT49BV320DT-70TU can be summarized as:(1)voltage on Vpp with respect to ground:-0.6 to 10.0V;(2)all output voltages with respect to ground:-0.6 to Vcc+0.6V;(3)all input voltages (including NC pins) with respect to ground:-0.6 to 6.25V;(4)temperature under bias:-55 to 125;(5)storage temperature:-65 to 150.Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The AT49BV320DT offers two sector protection modes, the Softlock and the Hardlock. The Softlock mode is optimized as sector protection for sectors whose content changes frequently. The Hardlock protection mode is recommended for sectors whose content changes infrequently. Once either of these two modes is enabled, the contents of the selected sector is read-only and cannot be erased or programmed. Each sector can be independently programmed for either the Softlock or Hardlock sector protection mode. At power-up and reset, all sectors have their Soft-lock protection mode enabled.
