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:
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
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’).
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.
