Manufacturer:NSC Description:The M28W320FS and M28W640FS are 32 Mbit (2Mbit x 16) and 64 Mbit (4Mbit x 16) Secure Flash memories. The devices can be erased electrically at block level and programmed in-system on a Word-by-Word basis using a 2.7V to 3.6V VDD supply for the circuitry and a 1.65V to 3.6V VDDQ supply for the Input/Output pins. An optional 12V VPP power supply is provided to speed up custom- er programming. The M28W320FS and M28W640FS feature 32Mbit and 64 Mbits respectively and have an asymmetrical block architecture with 4 KWord Pa- rameter Blocks and 32 KWord Main Blocks. The M28W320FST and M28W640FST have the Pa- rameter Blocks at the top of the memory address spacewhiletheM28W320FSBand M28W640FSB locate the Parameter Blocks start- ing from the bottom. Refer to Table 1., Figure 5. and Figure 6. for a detailed description of the de- vices memory architecture and map. All devices are equipped with hardware and soft- ware block protection features to avoid unwanted program/erase (modify) or read of the Flash mem- ory content: Hardware Protection: C When VPP VPPLK all blocks are protected against program or erase. Software Protection thanks to KRYPTO Security Features: C Modify Protection: volatile and non- volatile. C Read Protection. The KRYPTO Security features are described in a dedicated Application Note. Please contact STMi- croelectronics for further details. Two registers are available for protection purpose: The Protection Register The KRYPTO Protection Register. The Protection Register is a 192 bit Protection Register to increase the protection of a system de- sign. The Protection Register is divided into a 64 |
