Maxim Integrated DS1254YB2-100 Nonvolatile Timekeeping RAM

The DS1254YB2-100 from Maxim Integrated is a high-quality, nonvolatile timekeeping RAM that combines a full 1024k x 8 static RAM with an integrated real-time clock, a crystal, a long-life lithium battery, and an advanced power control circuitry. This innovative memory module provides a reliable and convenient solution for applications requiring both volatile and nonvolatile memory in a single space-saving package.

With its 5V ±10% operating voltage, the DS1254YB2-100 ensures compatibility with a wide range of microprocessors and digital systems. The memory is accessed in a byte-wide format, making it easy to integrate with existing architectures. The real-time clock (RTC) feature provides timekeeping capabilities that are accurate to within minutes per month over the full temperature range of 0°C to +70°C.

The device's nonvolatile attribute is particularly beneficial for systems that require data retention during power loss. The integrated lithium battery ensures that both the clock and RAM data are maintained for over 10 years in the absence of external power. This makes the DS1254YB2-100 an excellent choice for systems that cannot afford to lose critical data and need to maintain accurate timekeeping, such as embedded systems, utility meters, and industrial controllers.

Key features of the DS1254YB2-100 include:

• 1024k x 8 nonvolatile static RAM
• Integrated real-time clock with crystal
• Automatic power-fail chip deselect and write protection
• Write-protect voltages as low as 3.0V
• Long-life lithium battery with over 10 years of data retention
• Byte-wide access for easy integration

The DS1254YB2-100 comes in a reliable 32-pin EDIP (Encapsulated Dual In-line Package) or 32-pin TSOP (Thin Small Outline Package), providing flexibility for various design requirements. Maxim Integrated's commitment to high-quality and long-term reliability makes this product a smart choice for designers looking to enhance their systems with secure and persistent memory storage.
