Maxim Introduces DS3065WP, 8Mb NonVolatile SRAM Module with Embedded Real-Time Clock
Maxim Integrated Products introduces the DS3065WP, 8Mb NonVolatile (NV) SRAM module with embedded real-time clock (RTC) and battery in a PowerCap package. The DS3065WP consists of a static RAM, a nonvolatile (NV) controller, and a real-time clock (RTC). These components are packaged on a surface-mount substrate and require post-assembly attachment of a DS9034IPCX+ battery cap. Whenever VCC is applied to the module, it powers the clock and SRAM from the external power source, and allows the contents of the clock registers or SRAM to be modified. When VCC is powered down or out of tolerance, the controller write protects the memory contents and powers the clock and SRAM from the battery.
The DS3065WP allows system designers to migrate from lower memory densities without major changes in PCB layout. This device is ideally suited for data-acquisition systems, point-of-sale terminals, and other applications that need to continually update and store time-stamped data.
The DS3065WP is offered in a lead-free, 34-pin PowerCap package, which comes as a two-piece construction that allows surface-mount processing. The base unit includes the SRAM and RTC in a PCB module that is capable of being processed using standard IR reflow. The battery and crystal are included in a cap that is installed after all temperature and washing processes are complete.
The DS3065WP is fully specified to operate over the -40°C to +85°C extended industrial temperature range. Prices begin at $38.50 each in 1000 or up with FOB USA.
