Cypress have revealed that Schneider Electric has designed Cypress’s nonvolatile static random access memories into two of its new programmable automation controllers. The Schneider BMXCRA31210 and BMXERT1604 controllers each employ Cypress’s CY14B101Q2 1-Mbit nvSRAM as a time-stamp buffer. When an event such as the closure of a switch or power line defect is detected, the nvSRAM records it in a rolling buffer. These types of events can occur an infinite number of times during the lifetime of a product, so it is critical to have a very reliable component in this function.

The 1-Mbit serial nvSRAM device offers an industry-standard SPI interface and operates at frequencies up to 40 MHz. The nvSRAM devices do not use a battery, so they are environmentally-friendly and maintenance-free, which is especially important for process applications. Cypress nvSRAMs feature infinite read, write and recall cycles, with 20-year data retention, making them the best solution for applications requiring continuous high-speed writing of data and absolute non-volatile data security.

“Cypress’s serial nvSRAMs provide our BMXCRA31210 and BMXERT1604 programmable automation controllers with superior performance and reliability in a small form-factor,” said Marc Lafont, Plant Solution Control Marketing Director in the Industrial Control Business Unit of Schneider Electric. “It is critical for automation applications to have dependable event-logging, and Cypress’s nvSRAMs excel in this role.”

“The Cypress nvSRAM team worked very closely with us on these designs and provided excellent support,” said Jean-Jacques Adragna, Hardware Architect in the Industrial Control Business Unit of Schneider Electric. “We are pleased that the battery-free serial nvSRAMs are eco-friendly in addition to providing the reliability our customers demand.”

“We began selling serial nvSRAMs in 2010 and have seen rapid growth in this business segment, as evidenced by this design with a leading industrial control solutions provider such as Schneider Electric,” said Babak Taheri, Vice President of the Non-Volatile Products Business Unit at Cypress. “Our small-footprint serial nvSRAMs deliver unrivaled endurance, giving our customers a safety net they can depend on to store critical information when power is disrupted.”

The 1-Mbit serial nvSRAMs are available in 8-pin and 16-pin SOIC packages. Cypress’s nvSRAMs are manufactured on its S8 0.13-micron SONOS embedded non-volatile memory technology, enabling greater densities and improved access times and performance. nvSRAMs are ideal solutions for applications requiring absolute nonvolatile data security such as RAID systems, industrial control and automation (e.g. PLCs, motion control, motor drives and robotics), single board computers, POS terminals, eMetering, automotive, medical and data communication systems.
