Description

The M29W102BB is a 1 Mbit (64Kb 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 M29W102BB 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 M29W102BB in the memory are asymmetrically arranged, see Tables 3 and 4, Block Addresses. The first or last 32 Kwords have been divided into four additional blocks. The 8 Kword Boot Block can be used for small initialization code to start the microprocessor, the two 4 Kword Parameter Blocks can be used for parameter storage and the remaining 16 Kwords are 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 M29W102BB memory is offered in a TSOP40 (10 x 14mm) package and it is supplied with all the bits erased (set to '1').
