Memory IC datasheet and documents for DS1345WP-150

DS1345WP-150

Memory IC Overview

The DS1345WP-150 is a 3.3V 1024k Nonvolatile SRAM organized as 131,072 words by 8 bits. It features read and write access times of 100 ns with unlimited write cycle endurance. The device includes an integrated lithium energy source that activates automatically when VCC drops below 2.8 volts to prevent data corruption. It provides a typical standby current of 50 µA and guarantees a minimum data retention of 10 years without external power. The component utilizes a 34-Pin PowerCap Module package.

Memory IC Feature Summary

Automatically protects data during power loss by switching to internal lithium backup
Monitors battery capacity daily and asserts warning output if voltage falls below threshold
Resets processor via dedicated RST pin when out-of-tolerance power supply conditions occur
Ships with lithium energy source electrically disconnected until first power application

Memory IC Applications

PCB equipment identification and registration
Network node memory storage
System configuration data retention

Memory IC Procurement Notes

Verify the specific suffix 'WP-150' against official documentation, as standard listings typically reference 'WP-100'. Confirm RoHS compliance status for the exact ordering code. Ensure the separate DS9034PC PowerCap module is included in the bill of materials, as it is required to complete the nonvolatile function. Check for industrial temperature range variants if operating outside commercial limits.

Memory IC Selection Notes

Select this component for applications requiring high-speed parallel access combined with nonvolatile data retention. It serves as a direct upgrade replacement for standard SRAM, EEPROM, or Flash components. Consider the 34-PowerCap package constraints and the necessity of pairing with a compatible snap-on battery module. Verify that the system can accommodate the open-drain outputs for the reset and battery warning signals.

Memory IC Part Context

This part belongs to the DS1345W family of 3.3V Nonvolatile SRAMs manufactured by Analog Devices Inc./Maxim Integrated. The family integrates static RAM with control circuitry and a lithium energy source. These devices are designed to replace traditional volatile memory solutions while eliminating the need for complex backup circuitry.
