64 Mbit 4Mb X16, Boot Block 3V Supply Flash Memory

The M28W640EC is a 64 Mbit (4 Mbit x 16) non- volatile Flash memory that CAN be erased electri- cally 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 device features an asymmetrical blocked ar- chitecture. The M28W640EC has an array of 135 blocks: 8 Parameter Blocks of 4 KWord and 127 Main Blocks of 32 KWord. M28W640ECT has the Parameter Blocks at the top of the memory ad- dress space while the M28W640ECB locates the Parameter Blocks starting from the bottom. The memory maps are shown in Figure 5, Block Ad- dresses. The M28W640EC features an instant, individual block locking scheme that allows any block to be locked or unlocked with no latency, enabling in- stant code and data protection. All blocks have three levels of protection. They CAN be locked and locked-down individually preventing any acciden- tal programming or erasure. There is an additional hardware protection against program and erase. When VPP VPPLK all blocks are protected against program or erase. All blocks are locked at Power Up. By STMicroelectronics
