DS1213B

Part points

• The DS1213B chip is a versatile nonvolatile SRAM (NVSRAM) device with a 4Kbit memory array. It combines the functionality of a standard SRAM with the nonvolatile data storage capabilities of an EEPROM. It offers high-speed access to data during normal operation and automatically saves the contents of the memory array to the EEPROM when the power supply is interrupted, ensuring data integrity and retention even during power loss.

• Equivalent

  The equivalent products of the DS1213B chip include the DS1213, DS1213C, DS1213D, DS1213F, and DS1213G.

• Features

  The DS1213B is a real-time clock module with a crystal frequency of 32.768kHz. It offers a battery-backed NV SRAM with a capacity of 256 bytes, providing nonvolatile storage for data. The module is capable of counting time in seconds, minutes, hours, days of the week, date, month, and year. It also has an alarm feature with interrupt capability.

• Pinout

  The DS1213B has 8 pins. Its functions include providing access to external memory for non-volatile storage of data, along with supporting direct interface to microprocessors and other devices.

• Manufacturer

  The DS1213B is manufactured by Maxim Integrated Products, Inc. It is an American company specializing in designing, developing, and manufacturing analog and mixed-signal integrated circuits.

• Application Field

  The DS1213B is a low-voltage, 1024-bit, programmable read-only memory (EPROM) with a built-in real-time clock (RTC) designed for applications that require a permanent, tamper-proof, time-stamped record. It is commonly used in applications such as metering, industrial control, medical devices, data logs, and security systems.

• Package

  The DS1213B chip is offered in a 6-pin TSOC package. The package size measures 3.00mm x 4.00mm, with a 0.65mm lead spacing.
