STMicroelectronics M29W200BT55N1 Flash Memory

The M29W200BT55N1 is a 2 Mbit (256Kb x8 or 128Kb x16) non-volatile flash memory module designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This high-performance memory device operates at a supply voltage of 2.7V to 3.6V, making it an excellent choice for low-power applications that require reliable data storage and retrieval.

With its 55ns access time, the M29W200BT55N1 offers fast read capabilities, which is crucial for applications where quick data access is necessary. This feature makes the device suitable for a wide range of uses, including embedded systems, consumer electronics, and automotive applications where speed and dependability are of utmost importance.

The M29W200BT55N1 is organized as either 256K bytes of 8 bits each or 128K words of 16 bits each, depending on the mode of operation. This flexibility allows designers to choose the most appropriate data bus configuration for their specific application requirements. The device also supports a standard memory mapping, with boot blocks at the top or bottom, which are ideal for storing code that requires high protection from accidental erasure.

One of the key features of this flash memory is its boot block protection. The M29W200BT55N1 includes a hardware lock that secures the boot block regions to prevent unintentional programming or erasure. This is particularly important for critical code such as firmware or bootloaders that must remain stable over the product's lifetime.

STMicroelectronics has designed the M29W200BT55N1 with a range of programming and erasure features. The device supports byte and word programming, block erase, and chip erase operations, allowing for flexibility in managing data storage. The memory module also includes a status register that provides details on the completion of programming or erase cycles, as well as the detection of potential errors.

For ease of integration, the M29W200BT55N1 is available in a 48-pin TSOP (Thin Small Outline Package) that is surface-mountable, saving precious board space and enabling more compact designs. Its compatibility with JEDEC standards ensures that it can be used as a drop-in replacement for other standard flash memory devices, simplifying the upgrade process for existing designs.

In summary, the M29W200BT55N1 from STMicroelectronics is a robust and reliable flash memory solution that offers fast access times, flexible organization, and secure boot block protection, making it a smart choice for designers in need of a high-quality memory component.
