10 / 57 page M36W432T, M36W432B 10/57 Flash Memory Component TheFlash Memory is a32Mbit (2Mbit x 16) de- vice that can be erased electrically at the block level and programmed in-system on a Word-by- Word basis. These operations can be performed using a single low voltage (2.7 to 3.3V) supply and the VDDQF for device I/0 operation feature the same voltage range. An optional 12V VPPF power supply is provided to speed up customer pro- gramming. The device features an asymmetrical blocked ar- chitecture with an array of 71 blocks: 8 Parameter Blocks of 4KWord and63MainBlocks of 32 KWord. The M36W432T device has the Flash Memory Parameter Blocks at the top of the mem- ory address space while the M36W432B device lo- cates the Parameter Blocks starting from the bottom. The memory maps are shown in Figure 5, Block Addresses. The Flash Memory 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 VPPF ≤ VPPLK all blocks are protected against program or erase. All blocks are locked at Power Up. Each block can be erased separately. Erase can be suspended in order to perform either read or program in any other block and then resumed. Program can be suspended to read data in any other block and then resumed. Each block can be programmed and erased over 100,000 cycles. The device includes a 128 bit Protection Register and a Security Block to increase the protection of a system design. The Protection Register is divid- ed into two 64 bit segments, the first one contains a unique device number written by ST, while the second one is one-time-programmable by the us- er. The user programmable segment can be per- manently protected. The Security Block, parameter block 0, can be permanently protected by the user. Figure 6, shows the Flash Security Block Memory Map. Program and Erase commands are written to the Command Interface of the memory. An on-chip Program/Erase Controller takes care of the tim- ings necessary for program and erase operations. The end of a program or erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards. |
