2Kx16 Asynchronous dual port SRAM complements existing range for Military, Aerospace and Railroad applications
The QP7133SA/LA are CMOS Fast 2K x 16 Dual-Port Static RAMs (SRAM). QP Semiconductor designed the
QP7133SA/LA to be direct replacements for the IDT7133SA/LA. They are designed to be used as stand-alone Dual-Port RAMs in 16 bit applications. The QP7133SA/LA support asynchronous access for reads or writes to any location in memory via two independent ports with separate control and address and I/O pins that function identically to the IDT7133SA/IDT7133LA.
The QP7133SA/LA have an automatic power down feature controlled by the appropriate Chip Enable ( CE ) pin that puts each port into a very low standby power mode. The QP7133SA/LA utilize CMOS high-performance technology which allows access times as fast as 35ns and low power consumption typically at 750mW. The QP7133LA is the low-power version which offers a battery backup data
retention capability with typical power consumption of 10μW from a 2V source.
The QP7133SA/LA are available in hermetic ceramic 68-pin PGA and ceramic 68-pin Flatpack packages. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
