Hello, Welcome to Dasenic

The STMicroelectronics M48T18-150PC1 is a 5V, 512Kb (64K × 8bit) TIMEKEEPER® SRAM with a non-volatile element fabricated in a CMOS process. It combines the function of a static RAM, a non-volatile controller, and monolithic timekeeper in the same package. It provides a means of battery backup power, for a list of countable binary or BCD seconds, minutes, hours, days, date of the month, months, and years, with less than 1-minute average time drift per month, typically in the temperature range of 0°C to +40°C. Functions: 1. Non-Volatile Controller: Maintains time and date even when the system power is off, ensuring accurate timekeeping and data retention. 2. Static RAM: Provides volatile memory for data storage and retrieval during system operation. 3. Battery Backup: Enables the device to continue functioning using a battery to retain data and time information in case of power loss. Applications: The M48T18-150PC1 is commonly used in applications such as: 1. Embedded Systems 2. Industrial Control Systems 3. Data Loggers 4. Test and Measurement Equipment 5. Real-Time Clocks Alternative Components: Some alternative components to the M48T18-150PC1 include similar timekeeping ICs from other manufacturers, such as Maxim Integrated, Renesas Electronics, and Texas Instruments. Embedded Modules: The M48T18-150PC1 is often used in embedded modules for real-time clock and non-volatile SRAM functionality, providing system designers with an integrated solution for timekeeping and data retention.
