The AT49BV512-12TI is a Memory device categorizes in the non-volatile and single-power Flash memory segment of the memory market. It is a sleek, low voltage, serial access memory providing the memory user with a substantial code storage capacity while limiting the demands imposed by operating voltage. It consists of 512Kbits of Flash memory in a single SoC device and supports an array of serial access protocols offering the user considerable flexibility in system design.

The AT49BV512-12TI is capable of operating at 1.8V, 2.7V, 3V, 3.3V and 5V. The device is ideal for cost sensitive applications such as low voltage non-volatile memory for enhanced system performance. Its programming, erasing and read capability extends the boundaries of portable data storage and system design. The benefits of single power supply simplifies system logic and saves board space.

Applications of the AT49BV512-12TI device include embedded controllers, data logging, data recording, automotive and industrial applications. Other uses include general embedded control, handheld computers, white goods, POS terminals, medical and networking equipment.

The AT49BV512-12TI works using a 4-wire serial interface. It supports Dual SPI, SPI and Serial Peripheral Interface (SPI) master modes and can exchange data with an external host microcontroller in both input and output directions. The low power consumption of the device allows it to operate on a single power supply of just 1.8V or 2.7V.

Data is stored in the AT49BV512-12TI device by programming it through one of the three supported programming protocols: SPI write, Serial SPI Write or CFI write. Data stored in the device can then be read from the device by pulling on the Chip Select line of the 4-wire serial interface. This allows the user to retrieve data even if the device is operating at lower voltage levels.

The AT49BV512-12TI can be erased by the conventional use of a “bulk erase” protocol or selectively with the use of a “block erase” protocol. The device features an Improved Bulk Erase (IBE) protocol, which enables large sections of memory to be erased in a single operation.

The AT49BV512-12TI is a high-density, low voltage non-volatile memory device, offering excellent value for cost sensitive applications. It has a wide variety of uses from embedded controllers, data recording, automotive and industrial applications to general embedded control devices. Its simple but powerful 4-wire interface and low voltage operation make it an ideal choice for low power system designs.
