Instructions
Seven instructions are defined to perform Read
Array, Auto Select (to read the ElectronicSignature
or Block ProtectionStatus), Program, Block Erase,
Chip Erase, Erase Suspend and Erase Resume.
The internal P/E.C. automatically handles all tim-
ing and verification of the Program and Erase
operations. The Status Register Data Polling, Tog-
gle, Error bits and the RB output may be read at
any time, during programming or erase, to monitor
the progress of the operation.
Instructions are composed of up to six cycles. The
first two cycles input a Coded sequence to the
Command Interfacewhich iscommon to all instruc-
tions (see Table 8).
The third cycle inputs the instruction set-up com-
mand. Subsequent cycles output the addressed
data, Electronic Signature or Block Protection
Status for Read operations. In order to give addi-
tional data protection, the instructions for Program
and Block or Chip Erase require further command
inputs. For a Program instruction, the fourth com-
mand cycle inputs the address and data to be
programmed. For an Erase instruction (Block or
Chip), the fourth and fifth cycles input a further
Coded sequence before the Erase confirm com-
mand on the sixthcycle. Erasure of a memory block
may be suspended, in order to read data from
another block or to program data in another block,
and then resumed.
When power is first applied or if VCC falls below
VLKO, the command interface is reset to Read
Array.
