STMicroelectronics M29F400BB45N6E Flash Memory

The M29F400BB45N6E is a high-performance 4 Mbit (4,194,304 bits) Flash memory device from STMicroelectronics, designed with a flexible architecture for a wide range of applications. This non-volatile memory product offers an optimal combination of density, performance, and reliability, making it suitable for applications that require data and program storage that can withstand frequent reprogramming and erasure cycles.

Constructed with a boot block architecture, the M29F400BB45N6E features a 4 Mbit memory array organized as 8 blocks of 64 Kbytes each. One of these blocks, located at the top or bottom of the memory map, is designated as a boot block where critical code such as the system’s firmware or boot code is typically stored. This boot block can be write-protected to prevent accidental alteration, ensuring the integrity of the boot code.

The M29F400BB45N6E operates with a 5V power supply for read and write operations, and it provides access times as fast as 45ns, which is ideal for high-speed microprocessors and high-performance applications. The device supports a wide temperature range, making it reliable for use in various environmental conditions.

Featuring a 16-bit bus width, the M29F400BB45N6E allows for efficient interfacing with a broad range of microcontrollers and processors. It also supports industry-standard commands for Flash memories, including read, erase, and program operations. The device includes features such as erase suspend and resume capabilities, which allow the user to interrupt an erase operation to read data from or program data to a different block of the memory.

The M29F400BB45N6E is offered in a 44-pin TSOP (Thin Small Outline Package) that is both space-saving and suitable for PCMCIA and other applications requiring a small footprint. With its robust design and proven technology, the M29F400BB45N6E from STMicroelectronics is an excellent choice for designers seeking a reliable and flexible Flash memory solution.
