Maxim Integrated DS1230Y-100 Nonvolatile SRAM

The DS1230Y-100 is a robust, high-performance nonvolatile static RAM product from Maxim Integrated, designed to retain data without the need for a backup battery. This 256k NV SRAM (nonvolatile static RAM) integrates power-fail deselect circuitry and an internal lithium energy source to ensure that data is preserved when the power supply is compromised, making it an ideal memory solution for a wide range of data storage applications.

With a 100 ns access time, the DS1230Y-100 provides a fast and reliable interface for critical data retention operations. Its direct compatibility with 28-pin, 32k x 8 nonvolatile SRAMs makes it a convenient drop-in replacement for standard SRAMs, offering a seamless upgrade path for systems requiring nonvolatile memory solutions.

The DS1230Y-100 features a fully static operation, which means that there is no clock or timing strobe required. The simplicity of its interface allows for easy integration into a variety of microprocessor-based systems. The device operates over a wide voltage range, typically from 4.5V to 5.5V, providing flexibility in accommodating different power supply levels.

Designed with reliability in mind, the DS1230Y-100 includes an automatic write-protection feature that engages during power-down or power-up events. This ensures that data integrity is maintained even under adverse power conditions. The internal lithium battery has a lifespan of over 10 years, guaranteeing long-term data retention without the need for external power or periodic data refreshing.

The DS1230Y-100 is housed in a rugged, 28-pin, 600-mil DIP (dual in-line package) or SOIC (small outline integrated circuit) package, providing a compact footprint for space-constrained applications. Its industrial temperature range from -40°C to +85°C enables deployment in environments subject to extreme conditions.

In summary, Maxim Integrated's DS1230Y-100 is a high-quality, durable nonvolatile SRAM module that offers fast access times, ease of use, and a long-term data retention solution, making it a top choice for applications requiring dependable nonvolatile memory.
