3.5 Read Identifier Codes
The read identifier codes operation outputs the
manufacturer code, device code, block lock configuration
codes for each block and the permanent lock configuration
code (see Figure 4). Using the manufacturer and device
codes, the system CPU can automatically match the device
with its proper algorithms. The block lock and permanent
lock configuration codes identify locked and unlocked
blocks and permanent lock-bit setting.
3.6 Write
Writing commands to the CUI enable reading of device
data and identifier codes. They also control inspection and
clearing of the status register. When V
CC
=2.7V-3.6V and
V
CCW
=V
CCWH1/2
, the CUI additionally controls block
erase, full chip erase, word/byte write and lock-bit
configuration.
The Block Erase command requires appropriate command
data and an address within the block to be erased. The Full
Chip Erase command requires appropriate command data
and an address within the device. The Word/Byte Write
command requires the command and address of the
location to be written. Set Permanent and Block Lock-Bit
commands require the command and address within the
device (Permanent Lock) or block within the device
(Block Lock) to be locked. The Clear Block Lock-Bits
command requires the command and address within the
device.
The CUI does not occupy an addressable memory
location. It is written when WE# and CE# are active. The
address and data needed to execute a command are latched
on the rising edge of WE# or CE# (whichever goes high
first). Standard microprocessor write timings are used.
Figures 16 and 17 illustrate WE# and CE# controlled write
operations.
4 COMMAND DEFINITIONS
When the V
CCW
voltage
≤
V
CCWLK
, read operations from
the status register, identifier codes, or blocks are enabled.
Placing V
CCWH1/2
on V
CCW
enables successful block
erase, full chip erase, word/byte write and lock-bit
configuration operations.
Device operations are selected by writing specific
commands into the CUI. Table 3 defines these commands.
