STMicroelectronics M48Z02-150PC1 Zero Power SRAM
The M48Z02-150PC1 is a 16 Kbit (2K x 8) Zero Power SRAM, which integrates power-fail deselect circuitry and battery control logic on a single monolithic silicon chip. Manufactured by STMicroelectronics, this device is designed to maintain the integrity of stored data with no additional power supply, making it an ideal solution for systems that require reliable non-volatile memory storage.
The M48Z02 operates like a standard Static Random Access Memory (SRAM) during normal operation, with standard functionality over the full supply voltage range of 4.5 to 5.5 volts. It features a fast access time of 150 ns, allowing for quick read and write operations, which is crucial for high-speed microprocessors and computing applications.
One of the key features of the M48Z02-150PC1 is its integrated lithium battery, which automatically switches on to provide the necessary power to retain data when the main power supply drops below a certain threshold. This automatic power-fail chip deselect circuitry ensures data preservation for over 10 years in the absence of power. Additionally, the battery is non-rechargeable, ensuring long-term reliability and stability of the memory content.
This SRAM comes in a 24-pin DIP (Dual In-line Package), making it compatible with standard sockets and easy to integrate into a wide range of applications. The M48Z02-150PC1 is particularly suitable for use in systems where data needs to be preserved during power loss, such as real-time clocks, microcontroller backup memory, and configuration settings storage in various electronic devices.
Moreover, the M48Z02-150PC1 is designed with a write protect voltage (VPFD = Power-fail Deselect Voltage) that guarantees write protection during power transitions, preventing data corruption during unstable conditions. This feature, along with the low power consumption and high data retention capabilities, makes the M48Z02-150PC1 a reliable and essential component for critical memory applications.
For electronic designs that demand the highest level of data security and integrity, the STMicroelectronics M48Z02-150PC1 Zero Power SRAM is an excellent choice, providing a robust non-volatile memory solution that designers can trust.
