Pretec 4MB SRAM Card

Pretec SRAM cards features high speed, reprogrammable, non-volatile solid state memory technology with low power consumption for maximum battery life and reliable data retention in a wide range of mobile and embedded applications.

Compliant to the industry standard PCMICA/JEIDA specifications and in support of standard DOS file system, the card is well suited for data storage in Embedded PC, Palmtops, Sub-notebook PC, PDA, PCA, and Digital Cameras. Pretec manufactures and markets SRAM products in a variety of form factors and capacities. Additionally, Pretec offers customized SRAM solutions tailored to specific application, device, and design requirements.

The Pretec PCMCIA SRAM Card is the industries longest running SRAM PC Card due to it's unique design win with rechargeable built in battery which charges from the host PCMCIA bus, allowing for the main battery to be replaced without data loss.

Each SRAM card is designed with the dual back-up battery system - a replaceable but non-rechargeable 3V lithium battery (primary battery) and an on-board rechargeable but non-replaceable battery (secondary battery) for data retention. This design allows replacement of primary battery without data loss for approximately 20 minutes. In the event, digital signals on the card were used to alarm the user whether the primary battery should be replaced to prevent the loss of stored data. The write protect switch on the SRAM card provides a useful measure of protection from inadvertently over-writing stored data.
