The M25PX32-VMW6E device, a Memory, is the first 32Mbit addition to the Flash family, Spansion’s FlashPlus memory. The device provides increased memory density and low-power consumption while extending the range of Spansion’s production-proven serial Flash devices. The M25PX32-VMW6E can be used for remapping memory, increasing program storage capacity, and distributed computing applications. It is suitable for applications supporting low-voltage operation and providing extended storage life.

The M25PX32-VMW6E device is constructed of a single polymer/silicon composite. The device is organized as 256Mb x 32 and is fabricated on a 90-nm process. The memory array is divided into 16,258 sectors of 16Kb each, and the smallest erasable unit is the sector. The device is available in 8-pin and the package sizes are 3.9 x 5.0 mm and 5.0 x 6.5 mm. It supports single-byte and multiple-byte programming and provides a security register, which helps prevent code and critical data theft. The device also has a high-speed read performance of up to 85 MHz (1.7V) and 50 MHz (2.7V).

The M25PX32-VMW6E operates from a single 2.7-3.6V voltage supply and is capable of operating over an extended temperature range from -40 °C to 85 °C. The device does not require any external components; the write protect line, status register and associated address lines are all internally controlled. The device\'s internal circuitry consists of a control register, address register, and a programming register. The address register is used to store the address of the memory or data to be written. The control register is used to control data writing and erasing, while the programming register is used to store the data to be written.

The M25PX32-VMW6E also offers a full selection of accelerated read modes that enable data to be read faster than the standard read mode. These include fast read, dual read, quad read, and octal read mode. Fast read mode provides an 18 MHz read speed while dual read mode provides an 18 MHz read speed with 16-bit word width. Quad read mode offers a 36 MHz read speed with a 32-bit word width and octal read mode provides a 54 MHz read speed with a 64-bit word width.

The M25PX32-VMW6E has excellent erase and write performance. The device’s internal erase engine assures that all bits within the sector are erased for reliable rewrite performance. The device also does not require any code or data protection to ensure a long data retention time. The device features auto-deselect for better erase and write performance and supports 16-byte page programming and the atomic write feature. Co-processor instructions and a page lock feature helps reduce program times and improves reliability in mission critical applications.

The M25PX32-VMW6E is perfect for applications where both low cost and high-capacity Flash memory are needed. This device can be used in a wide range of applications such as printers, faxes, POS (Point-of-Sale) terminals, communication systems, automotive infotainment systems, navigation equipment and other embedded systems. The device is also well suited for use in systems with limited space, since its small package size facilitates integration into existing systems.

In summary, the M25PX32-VMW6E FlashPlus Memory device provides a high-density, low-power, and cost effective solution for a wide range of memory-dependent applications. Its small package size and wide operating voltage range make it an ideal device for various embedded applications.
