Memory IC datasheet and documents for DS1330WP-100IND

DS1330WP-100IND

Memory IC Overview

The DS1330WP-100IND is a 3.3V, 256k Nonvolatile SRAM module organized as 32,768 words by 8 bits, featuring a 34-pin PowerCap Module package. It provides read and write access times of 100 ns with unlimited write cycle endurance. The device includes an integrated lithium battery backup system that automatically engages during power loss to prevent data corruption, ensuring a minimum data retention of 10 years. Designed for the industrial temperature range of -40°C to +85°C, it incorporates dedicated circuitry for VCC monitoring and daily battery capacity checks.

Memory IC Feature Summary

Automatically protects data during power loss by switching to internal lithium energy source and enabling write protection
Includes power supply monitor that resets processor and holds reset during VCC ramp-up
Features battery monitor that checks remaining capacity daily and asserts warning output if voltage drops below trip point
Lithium battery is electrically disconnected until first power application to retain freshness

Memory IC Applications

Upgrade replacement for 32k x 8 SRAM components
Upgrade replacement for EEPROM components
Upgrade replacement for Flash components

Memory IC Procurement Notes

Verify the specific IND suffix confirms the -40°C to +85°C industrial temperature rating. Confirm the requirement for a separate DS9034PC or DS9034PCI+ PowerCap unit, as these are ordered separately. Ensure compatibility with the 34-pin PowerCap Module land pattern and standardized pinout for nonvolatile SRAM products.

Memory IC Selection Notes

Select this component when a direct surface-mountable upgrade for existing SRAM, EEPROM, or Flash designs is required without additional support circuitry. Consider the 100 ns access time and 50 µA typical standby current for low-power applications. Verify that the system can accommodate the open-drain RST and BW outputs requiring external pullup resistors.

Memory IC Part Context

The DS1330W series consists of 3.3V 256k Nonvolatile SRAMs in a PowerCap Module package. This design allows the memory base to be reflow soldered while keeping the lithium backup battery separate until snapped on later. The module integrates self-contained lithium energy sources and control circuitry to monitor VCC conditions continuously.
