The M48Z12-150 is a 16 Kbit 2Kb x 8 ZEROPOWER® SRAM with a built-in 48-millimeter Real Time Clock (RTC) from STMicroelectronics. This innovative memory component is designed to provide a full-featured, battery-backed non-volatile memory solution for applications requiring data and time retention without the need for an external battery. The M48Z12-150 is particularly suitable for use in a wide range of industrial, telecommunications, and consumer electronics where the integrity of data and accurate timekeeping are critical.
Key Features
- Integrated Power-Fail Deselect (PFD) circuitry which automatically switches to the battery supply during power failures, thus preserving the integrity of the data stored within the device.
- Self-contained battery and crystal within the monolithic package, significantly reducing the component count and simplifying the design of the end product.
- Low Power Consumption with a typical standby current of only 2µA, which contributes to the overall energy efficiency of the system it is integrated into.
- 48-millimeter Real Time Clock which includes an oscillator, divider chain, and control logic to provide timekeeping functions that continue to operate in the absence of external power.
- Non-volatile, High-reliability Data Storage with data retention guaranteed for a minimum of 10 years in the absence of external power.
Applications
The versatility of the M48Z12-150 ZEROPOWER® SRAM makes it ideal for a variety of applications, including:
- Utility meters
