Part points

  • The MK48Z02B-15 chip is a non-volatile static ram (nvsram) designed by cypress semiconductor. it combines sram with a power-fail control circuit to retain data during power loss. with a density of 2 mb, it offers high-speed access for various applications. the chip has a 15 ns access time and operates on a wide voltage range from 4.5v to 5.5v. it is commonly used in industrial control systems, gaming machines, and other devices requiring non-volatile memory.
  • Features

    The main features of the MK48Z02B-15 are: - nonvolatile static ram (nvsram) with a capacity of 64 kilobits - integrated real-time clock/calendar (rtc) - 10-year minimum data retention in the absence of power - automatic battery back-up - industrial temperature range (-40°c to +85°c) - low power consumption (4ma typical) - access times of 70 to 90ns
  • Pinout

    The MK48Z02B-15 is an integrated real-time clock (rtc) module. it has a 28-pin count and functions as a nonvolatile ram with a built-in lithium battery to maintain time and date information even when the system is powered off. additionally, it includes a crystal oscillator and a clock/calendar circuit for accurate timekeeping.
  • Manufacturer

    The manufacturer of the MK48Z02B-15 is stmicroelectronics. it is a multinational semiconductor company headquartered in geneva, switzerland. stmicroelectronics specializes in designing, developing, manufacturing, and marketing a wide range of integrated circuits (ics), including microcontrollers, sensors, power management, and more.
  • Application Field

    The MK48Z02B-15 is a nonvolatile static ram (nvsram) with a 2 mb density. it is typically used in applications such as data loggers, industrial control systems, medical equipment, and gaming machines, where a combination of high-speed, high-density, and nonvolatile storage is required to retain data during power loss or system reset.
  • Package

    The MK48Z02B-15 chip is housed in a 28-pin dip (dual in-line package) with a body size of approximately 9.8 mm x 6.5 mm.
