DS1330WP-100+

Introduction

DS1330WP-100+ is a high reliability non-volatile SRAM. It offers batteries-free data retention and an extensive temperature range of -40 to +125°C, making it ideal for demanding industrial and military applications. It is a ‘drop-in’ replacement for the 16Kx8 SRAM which makes it a perfect fit for existing designs. DS1330WP-100+ is available in a wide range of packages, including PLCC, DIP, and SOIC.

Applications

DS1330WP-100+ is ideally suited for harsh environments of industrial and military applications. Its robust design and wide operating temperature range make it an ideal solution for applications such as:

• Industrial Control Systems – Automotive, Medical, Avionics, Power Supply and Lighting
• Embedded Controllers – SCADA Systems, PLCs, ADC/DAC applications
• Rugged Mobile Devices – Military and Emergency Communications
• Sensors and Monitors – Pressure, Temperature, Flow, Position

Working Principle

DS1330WP-100+ utilizes a patented DRAM technology that enables reliable data storage in the presence of power interruptions. This makes the device very suitable for industrial and military applications that may experience power outages due to harsh conditions or prolonged periods of inactivity. The device is coupled with an embedded lithium battery which allows it to maintain data retention in the event of power loss.

The embedded lithium battery powers an internal charge-pump, which maintains a constant supply of power to the device. The charge-pump also serves as a watchdog mechanism that automatically switches the device to low-power mode if the battery voltage falls below a pre-determined threshold. This provides a very low-power solution that helps to reduce system power consumption.

Conclusion

DS1330WP-100+ is a high reliability non-volatile SRAM that utilizes DRAM technology to enable reliable data storage in the presence of power interruptions. Its wide operating temperature range and robust design make it an ideal solution for industrial and military applications. It is a ‘drop-in’ replacement for the 16Kx8 SRAM, making it a perfect fit for existing designs. DS1330WP-100+ is available in a wide range of packages, including PLCC, DIP, and SOIC.
