Summary description

The M29W320D is a 32 Mbit (4Mb x8 or 2Mb x16) non-volatile memory that can be read,

erased and reprogrammed. These operations can be performed using a single low voltage

(2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode where it can be

read in the same way as a ROM or EPROM.

The memory is divided into blocks that can be erased independently so it is possible to

preserve valid data while old data is erased. Each block can be protected independently to

prevent accidental Program or Erase commands from modifying the memory. Program and

Erase commands are written to the Command Interface of the memory. An on-chip

Program/Erase Controller simplifies the process of programming or erasing the memory by

taking care of all of the special operations that are required to update the memory contents.

The end of a program or erase operation can be detected and any error conditions

identified. The command set required to control the memory is consistent with JEDEC

standards.

The blocks in the memory are asymmetrically arranged, see Figure 4 and Figure 5, Table 19

and Table 20. The first or last 64 Kbytes have been divided into four additional blocks. The

16 Kbyte Boot Block can be used for small initialization code to start the microprocessor, the

two 8 Kbyte Parameter Blocks can be used for parameter storage and the remaining 32

Kbyte is a small Main Block where the application may be stored.

Chip Enable, Output Enable and Write Enable signals control the bus operation of the

memory. They allow simple connection to most microprocessors, often without additional

logic.

The memory is offered in TSOP48 (12 x 20mm), and TFBGA48 (6x8mm, 0.8mm pitch)

packages. In order to meet environmental requirements, Numonyx offers the M29W320D in

ECOPACK® packages. ECOPACK packages are Lead-free. The category of second Level

Interconnect is marked on the package and on the inner box label, in compliance with

JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also

marked on the inner box label.

The memory is supplied with all the bits erased (set to 1).
