Overview

  • Single-Piece, Reflowable, 27mm x 27mm BGA Package Footprint
  • Internal Manganese Lithium Battery and Charger
  • Integrated Real-Time Clock
  • Unconditionally Write-Protects the Clock and SRAM when VCC is Out-of-Tolerance
  • Automatically Switches to Battery Supply when VCC Power Failures Occur
  • Reset Output can be Used as a CPU Supervisor
  • Interrupt Output can be Used as a CPU Watchdog Timer
  • Industrial Temperature Range (-40°C to + 85°C)

    • The DS3065W consists of a static RAM, a nonvolatile (NV) controller, a year 2000-compliant real-time clock (RTC), and an internal rechargeable manganese lithium (ML) battery. These components are encased in a surface-mount module with a 256-ball BGA footprint. Whenever VCC is applied to the module, it recharges the ML battery, powers the clock and SRAM from the external power source, and allows the contents of the clock registers or SRAM to be modified. When VCC is powered down or out-of-tolerance, the controller writeprotects the memory contents and powers the clock and SRAM from the battery. The DS3065W also contains a power-supply monitor output (active-low RST), as well as a user-programmable interrupt output (active-low IRQ/FT).
