PowerCap™ NV SRAM and Timekeeping Module

Horizontal Rule

Key Features

Product Summary

The patent-pending PowerCap module package enables Dallas Semiconductor to build true surface-mount Nonvolatile SRAM and Timekeeping products. A functional improvement and drop-in replacement for Dallas' Low Profile Module (LPM) package, the PowerCap Module package eliminates the need for a PLCC socket when surface-mounting. Rather than relying on a socket, PowerCap Modules feature a unique two-piece construction composed of a surface-mountable module base which houses the integrated circuit components, and a PowerCap containing temperature-sensitive battery and crystal components. During system assembly, customers reflow-solder module bases while the PowerCaps remain on the shelf, away from the high temperatures associated with surface-mount soldering. Following reflow, customers simply snap PowerCaps onto the module bases to form complete NV SRAM and Timekeeping modules.

Initial PowerCap product offerings come from three distinct families: 12series NV SRAMs, 13series NV SRAMs and 164x Timekeeping RAMs. Devices ranging from 8K x 8 to 512K x 8 are available now, and products of other memory sizes and from other functional families will gradually be released over the next few months. The initial device list is shown in the table below.

All NV SRAM module bases use the DS9034PC PowerCap (lithium battery only), while all Timekeeping module bases use the DS9034PCX (lithium battery and crystal). Both devices keep a tight grip on their modules bases, maintaining physical and electrical connection even during shock and vibration events. If battery capacity ever gets low in a PowerCap Module, DS9034 PowerCaps can be easily removed with a small flathead screwdriver and replaced.

Packages/Speeds

All PowerCap modules are 34-pin devices, and all have compatible pinouts for easy density and feature upgrades. NV SRAM products are available in 70ns and 100ns varieties, while Timekeeping RAMs are available in 120ns and 150ns speeds. Initial product offerings are all commercial operating temperature range (0° to 70°C). Industrial (-40° to 85°C) NV SRAM modules will be supported in the near future.

Applications

Nonvolatile SRAM and Timekeeping products are used in applications of all sorts in nearly every market segment in the electronics industry. PowerCap Modules serve to expand this broad market base. PowerCaps will certainly penetrate applications where surface-mount components are preferred. Their lower profile also allows them to fit into space-constrained applications where the taller DIP modules cannot. In addition, the ability to replace PowerCaps when their batteries run low allows products in this package to penetrate applications with life expectancies longer than 10 years.
