CY62137VLL-70ZXE is a member of Cypress\' family of Serial SRAMs. It is a low-power, high-performance static RAM that exhibits static memory cell characteristics while providing the full flexibility of cycle-independent accesses to its entire address space. Cypress\' CY62137VLL-70ZXE is organized as 256Kbits of static RAM in 16Kwords by 8bits of memory.

CY62137VLL-70ZXE is targeted for a variety of applications, ranging from automotive and consumer audio/video systems to communications and industrial automation. Its low source and sink current inputs, small form factor, and fast data access make it suitable for battery-powered portable applications.

The CY62137VLL-70ZXE follows the industry-standard Combined Pinout (CP) model with a three-mode design. The three modes are byte-wide, word-read, and word-write. It is also pin- and power-compatible with popular existing static RAMs in the CP model.

The CY62137VLL-70ZXE offers access rates of up to 70 MHz in the CP model, allowing for fast data access. It has a single 5 V power supply and operates over the extended temperature range of -40°C to +85°C.

The CY62137VLL-70ZXE works by first receiving an address from the address lines. This address is then decoded and used to access the memory. The data is then read from or written to the device depending on the type of operation. The CY62137VLL-70ZXE uses static RAM cells for storage, which allows for faster access times compared to traditional dynamic RAM.

The CY62137VLL-70ZXE integrates several key features to enable low-power operation, fast access times, and reliable operation. This includes a Programmable Output Driver Strength (PODS) mode, which allows the output driver strength to be adjusted to reduce power consumption. In addition, it has an Automatic Output High-Z feature, which shuts off the output drivers when the device is idle, reducing power consumption.

The CY62137VLL-70ZXE also is equipped with an internal self-refreshing circuit that automatically refreshes every cell in the device periodically, allowing for reliable operation in low-power standby modes. The refresh rate is programmable and can be adjusted to maximize power savings.

Finally, the CY62137VLL-70ZXE has a Selectable Address Mapping feature, which allows the user to select between two address mapping modes. This allows the user to optimize the address decoding and reduce power consumption.

Overall, the CY62137VLL-70ZXE is a low-power, high-performance static RAM that is well-suited for a variety of applications. Its fast data access, combined with its low-power features, make it an ideal memory choice for battery-powered portable applications.
