2 PRINCIPLES OF OPERATION
The LH28F160BJE-BTL90 flash memory includes an on-
chip WSM to manage block erase, full chip erase,
word/byte write and lock-bit configuration functions. It
allows for: 100% TTL-level control inputs, fixed power
supplies during block erase, full chip erase, word/byte
write and lock-bit configuration, and minimal processor
overhead with RAM-like interface timings.
After initial device power-up or return from reset mode
(see section 3 Bus Operations), the device defaults to read
array mode. Manipulation of external memory control pins
allow array read, standby and output disable operations.
Status register and identifier codes can be accessed
through the CUI independent of the V
voltage on V
erase, word/byte write and lock-bit configurations. All
functions associated with altering memory contents−block
erase,
configuration, status and identifier codes−are accessed via
the CUI and verified through the status register.
Commands are written using standard microprocessor
write timings. The CUI contents serve as input to the
WSM, which controls the block erase, full chip erase,
word/byte write and lock-bit configuration. The internal
algorithms are regulated by the WSM, including pulse
repetition, internal verification and margining of data.
Addresses and data are internally latched during write
cycles. Writing the appropriate command outputs array
data, accesses the identifier codes or outputs status register
data.
Interface software that initiates and polls progress of block
erase, full chip erase, word/byte write and lock-bit
configuration can be stored in any block. This code is
copied to and executed from system RAM during flash
memory updates. After successful completion, reads are
again possible via the Read Array command. Block erase
suspend allows system software to suspend a block erase
to read/write data from/to blocks other than that which is
suspend. Word/byte write suspend allows system software
to suspend a word/byte write to read data from any other
flash memory array location.
