For Program and Erase operations the necessary high voltages are generated inter- nally. The device supports synchronous burst read and asynchronous read from all the blocks of the memory array; at power-up the device is config- ured for page mode read. In synchronous burst mode, a new data is output at each clock cycle for frequencies up to 54MHz. The array matrix organization allows each block to be erased and reprogrammed without affecting other blocks. All blocks are protected against pro- gramming and erase at Power-up. Blocks can be unprotected to make changes in the application and then re-protected. A parameter block "Security block" can be perma- nently protected against programming and erasing in order to increase the data security. An optional 12V VPP power supply is provided to speed up the program phase at costumer production. An inter- nal command interface (C.I.) decodes the instruc- tions 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. Two status registers indicate the state of each bank. Instructions for Read Array, Read Electronic Sig- nature, Read Status Register, Clear Status Regis- ter, Write Read Configuration Register, Program, Block Erase, Bank Erase, Program Suspend, Pro- gram Resume, Erase Suspend, Erase Resume, Block Protect, Block Unprotect, Block Locking, Protection Program, CFI Query, are written to the memory through a Command Interface (C.I.) using standard micro-processor write timings. The memory is offered in TFBGA48, 0.5 mm ball pitch packages and it is supplied with all the bits erased (set to ’1’). |
