Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
2. Depends on range.

The M28W800T is a 8 Mbit non-volatile Flash memory that can be erased electrically at the block level and programmed in-system on a Word-by-Word basis. The device is offered in the TSOP48 (12 x 20 mm) and the BGA48 0.75mm ball pitch packages. When shipped, all bits of the M28W800 are in the '1' state.

The array matrix organisation M28W800T allows each block to be erased and reprogrammed without affecting other blocks. Each block can be programmed and erased over 100,000 cycles. V_DDQ allows to drive the I/O pin down to 1.65V. An optional 12V V_PP power supply is provided to speed up the programphase at customer production line environment.

An internal Command Interface (C.I.)M28W800T decodes the instructions to access/modify the memory content. The Program/Erase Controller (P/E.C.) automatically executes the algorithms taking care of the timings necessary for program and erase operations.Verification is performed too, unburdeningthe microcontroller, while the Status Register tracks the status of the operation.

The following instructions M28W800T are executed by the M28W800: Read Array, Read Electronic Signature, Read Status Register, Clear Status Register,Program, Block Erase, Program/Erase Suspend, Program/Erase Resume, CFI Query.
