Product Overview

The DS1345YP-100+ is a 1024K non-volatile SRAM with battery monitor in 34 pin PWRCP package. This 1,048,576bit, fully static, NV SRAM is organized as 131,072words by 8bits. It has a self contained lithium energy source and control circuitry which constantly monitors VCC for an out of tolerance condition. The lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption When an out of tolerance condition occurs. The lithium battery is electrically disconnected to retain freshness until power is applied for the first time. Additionally, the DS1345 device has dedicated circuitry for monitoring the status of VCC and status of internal lithium battery. This PowerCap module package device can be directly surface mountable and it is normally paired with DS9034 PC PowerCap to form complete NV SRAM module. The devices can be used in place of 128K x 8 SRAM, EEPROM, or flash components.
  • Supply voltage range from 4.5V to 5.5V
  • Operating temperature range from 0°C to 70°C
  • 10 years minimum data retention in the absence of external power
  • Data is automatically protected during power loss
  • Power supply monitor resets processor when VCC power loss occurs & holds in reset during VCC ramp-up
  • Battery monitor checks remaining capacity daily
  • Read and write access time of 100ns and write protection voltage of 4.37V
  • Unlimited write cycle endurance
  • Typical standby current of 50μA (active-low CE= VCC-0.5V) and operating current of 85mA
  • Detachment feature on PowerCap allows easy removal using a regular screwdriver
