M29W800AT, M29W800AB

DESCRIPTION

The M29W800A is a non-volatile memory that may

be erased electrically at the block or chip level and

programmed in-system on a Byte-by-Byte or

Word-by-Word basis using only a single 2.7V to

3.6V V

supply. For Program and Erase opera-

tions the necessary high voltages are generated

internally. The device can also be programmed in

standard programmers.

The array matrix organisation allows each block to

be erased and reprogrammed without affecting

other blocks. Blocks can be protected against pro-

graming and erase on programming equipment,

and temporarily unprotected to make changes in

the application. Each block can be programmed

and erased over 100,000 cycles.

Instructions for Read/Reset, Auto Select for read-

ing the Electronic Signature or Block Protection

status, Programming, Block and Chip Erase,

Erase Suspend and Resume are written to the de-

vice in cycles of commands to a Command Inter-

face using standard microprocessor write timings.

The device is offered in TSOP48 (12 x 20mm),

SO44 and TFBGA48 0.8 mm ball pitch packages.

Organisation

The M29W800A is organised as 1M x8 or 512K

x16 bits selectable by the BYTE signal. When

BYTE is Low the Byte-wide x8 organisation is se-

lected and the address lines are DQ15A–1 and

A0-A18. The Data Input/Output signal DQ15A–1

acts as address line A–1 which selects the lower

or upper Byte of the memory word for output on

DQ0-DQ7, DQ8-DQ14 remain at High impedance.

When BYTE is High the memory uses the address

inputs A0-A18 and the Data Input/Outputs DQ0-

DQ15. Memory control is provided by Chip Enable

E, Output Enable G and Write Enable W inputs.

A Reset/Block Temporary Unprotection RP tri-lev-

el input provides a hardware reset when pulled

Low, and when held High (at V

) temporarily un-

protects blocks previously protected allowing them

to be programed and erased. Erase and Program

operations are controlled by an internal Program/

Erase Controller (P/E.C.). Status Register data

output on DQ7 provides a Data Polling signal, and

DQ6 and DQ2 provide Toggle signals to indicate

the state of the P/E.C operations. A Ready/Busy

RB output indicates the completion of the internal

algorithms.

Memory Blocks

The devices feature asymmetrically blocked archi-

tecture providing system memory integration. Both

M29W800AT and M29W800AB devices have an

array of 19 blocks, one Boot Block of 16 KBytes or

8 KWords, two Parameter Blocks of 8 KBytes or 4

KWords, one Main Block of 32 KBytes or 16

KWords and fifteen Main Blocks of 64 KBytes or

32 KWords. The M29W800AT has the Boot Block

at the top of the memory address space and the

M29W800AB locates the Boot Block starting at the

bottom. The memory maps are showed in Tables

and

Each block can be erased separately, any combi-

nation of blocks can be specified for multi-block

erase or the entire chip may be erased. The Erase

operations are managed automatically by the P/

E.C. The block erase operation can be suspended

in order to read from or program to any block not

being erased, and then resumed.

Block protection provides additional data security.

Each block can be separately protected or unpro-

tected against Program or Erase on programming

equipment. All previously protected blocks can be

temporarily unprotected in the application.

Bus Operations

The following operations can be performed using

the appropriate bus cycles: Read (Array, Electron-

ic Signature, Block Protection Status), Write com-

mand, Output Disable, Stan-by, Reset, Block

Protection, Unprotection, Protection Verify, Unpro-

tection Verify and Block Temporary Unprotection.
