M29F016D

The M29F016D is a 16 Mbit (2Mb x8) non-volatile memory that can be read, erased and repro- grammed. These operations can be performed us- ing a single low voltage 5V 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 M29F016D is divided into 32 uniform blocks of 64Kbytes (see Figure 5, Block Addresses) that can be erased independently so it is possible to preserve valid data while old data is erased.
Blocks can be protected in groups of 4 to prevent accidental Program or Erase commands from modifying the memory. Program and Erase com- mands are written to the Command Interface of the memory. An on-chip Program/Erase Controller simplifies the process of programming or erasingthe memory by taking care of all of the special op- erations that are required to update the memory contents. The end of a program or erase operation can be detected and any error conditions identi- fied. The command set required to control the memory is consistent with JEDEC standards.

Chip Enable, Output Enable and Write Enable sig- nals M29F016D control the bus operation of the memory.They allow simple connection to most micropro-cessors, often without additional logic.

The memory M29F016D is offered in TSOP40 (10 x 20mm) and SO44 packages. Access times of 55, 70 and 90ns are available. The memory is supplied with all the bits erased (set to '1').
