By Business Wire News


Everspin Technologies, Inc., the world’s leading developer and manufacturer of discrete and embedded MRAM, and Koyo Electronics Industries, a leading manufacturer of highly reliable factory automation systems and automotive parts, today announced that Everspin’s MRAM is now designed into Koyo Electronics Industries’ new Direct Logic 205 (DL205) Series Programmable Logic Controllers (PLCs). Koyo’s DL205 PLC is the company’s most configurable and versatile solution in their portfolio, allowing up to five different CPU types, up to 16,384 I/O points, multiple communication options, Human Machine Interface (HMI), and a PID Controller with up to 16 built-in loops. Unlike other standard mainstream memories, Everspin’s MRAM enables data integrity and reliability in harsh environments, and instant event save in the event of a power loss and without the need for a battery.

“Koyo is a strong leader in modular PLC Automation for industrial and automotive companies in Japan and worldwide,” said Phill LoPresti, President and CEO of Everspin. “We are pleased Koyo has selected Everspin’s durable field-switched MRAM to provide unique, value-added benefits to Koyo’s customers.”

The DL205 Series PLCs and expansion modules from Koyo Electronics utilize 1-Megabit parallel interface (MR0A16A) MRAM from Everspin. Everspin’s field-switched MRAM is the fastest truly non-volatile memory on the market, offers extremely high data retention and unlimited endurance, and is offered in a variety of packages, interfaces (SPI, QSPI, x8 and x16 parallel), and densities (up to 16-Megabit). For MRAM benefits in higher density memory and storage applications, Everspin offers DDR-interface Spin-Torque MRAM (ST-MRAM).
