8 / 87 page  Description M58BW16F, M58BW32F 8/87 All blocks are protected during power-up. The M58BWxxF features five different levels of hardware and software block protection to avoid unwanted Program/Erase operations: ● Write/Protect Enable input, WP, hardware protects a combination of blocks from Program and Erase operations. The blocks to be protected are configured individually by issuing a Set Block Protection Configuration Register or a Clear Block Protection Configuration Register command. ● All Program or Erase operations are blocked when Reset, RP, is held Low. ● A Program/Erase Enable input, PEN, is used to protect all blocks, preventing Program and Erase operations from affecting their data. ● A permanent user-enabled protection against Modify operations is available: – on one specific 128-Kbit parameter block in the M58BW32F – block 1 for bottom devices or block 72 for top devices – on two specific 64-Kbit parameter blocks in the M58BW16F – blocks 2 and 3 for bottom devices or blocks 36 and 35 for top devices. A Reset/Power-down mode is entered when the RP input is Low. In this mode the power consumption is reduced to the standby level, the device is write protected and both the Status and Burst Configuration Registers are cleared. A recovery time is required when the RP input goes High. A manufacturer code and a device code are available. They can be read from the memory allowing programming equipment or applications to automatically match their interface to the characteristics of the memory. Finally, the M58BWxxF features a 64-bit unique device identifier (UID) which is programmed by Numonyx on the production line. It is unique for each die and can be used to implement cryptographic algorithms to improve security. Information is available in the CFI area (see Table 32: M58BW16F extended query information). The memory is offered in PQFP80 (14 x 20 mm) and LBGA80 (1.0 mm pitch) packages and it is supplied with all the bits erased (set to ’1’). |
