COMMAND INTERFACE

All Bus Write operations to the memory are inter-

preted by the Command Interface. Commands

consist of one or more sequential Bus Write oper-

ations. Failure to observe a valid sequence of Bus

Write operations will result in the memory return-

ing to Read mode. In this case, after at least 50ns,

an address transition or Chip Enable going Low is

required before reading correct data. The long

command sequences are imposed to maximize

data security.

The commands are summarized in Table 5, Com-

mands. Refer to Table 5 in conjunction with the

text descriptions below.

Read/Reset Command. The Read/Reset com-

mand returns the memory to its Read mode where

it behaves like a ROM or EPROM. It also resets

the errors in the Status Register. Either one or

three Bus Write operations can be used to issue

the Read/Reset command.

If the Read/Reset command is issued during a

Block Erase operation or following a Programming

or Erase error then the memory will take up to 10

µs

to abort. During the abort period no valid data can

be read from the memory. Issuing a Read/Reset

command during a Block Erase operation will

leave invalid data in the memory.

Auto Select Command. The Auto Select com-

mand is used to read the Manufacturer Code, the

Device Code and the Block Protection Status.

Three consecutive Bus Write operations are re-

quired to issue the Auto Select command. Once

the Auto Select command is issued the memory

remains in Auto Select mode until another com-

mand is issued.

From the Auto Select mode the Manufacturer

Code can be read using a Bus Read operation

with A0 = VIL and A1 = VIL. The other address bits

may be set to either VIL or VIH. The Manufacturer

Code for STMicroelectronics is 20h.

The Device Code can be read using a Bus Read

operation with A0 = VIH and A1 = VIL. The other

address bits may be set to either VIL or VIH. The

Device Code for the M29F080A is F1h.

The Block Protection Status of each block can be

read using a Bus Read operation with A0 = VIL,

A1 = VIH, and A16-A19 specifying the address of

the block. The other address bits may be set to ei-

ther VIL or VIH. If the addressed block is protected

then 01h is output on the Data Inputs/Outputs, oth-

erwise 00h is output.

Program Command. The

Program

command

can be used to program a value to one address in

the memory array at a time. The command re-

quires four Bus Write operations, the final write op-

eration latches the address and data in the internal

state machine and starts the Program/Erase Con-

troller.

If the address falls in a protected block then the

Program command is ignored, the data remains

unchanged. The Status Register is never read and

no error condition is given.

During the program operation the memory will ig-

nore all commands. It is not possible to issue any

command to abort or pause the operation. Typical

program times are given in Table 6. Bus Read op-

erations during the program operation will output

the Status Register on the Data Inputs/Outputs.

See the section on the Status Register for more

details.

After the program operation has completed the

memory will return to the Read mode, unless an

error has occurred. When an error occurs the

memory will continue to output the Status Regis-

ter. A Read/Reset command must be issued to re-

set the error condition and return to Read mode.

Note that the Program command cannot change a

bit set at ’0’ back to ’1’. One of the Erase Com-

mands must be used to set all the bits in a block or

in the whole memory from ’0’ to ’1’.
