Event data recorder integrates F-RAM memory
-- Test & Measurement World, 6/1/2008
Ramtron International, a developer of nonvolatile ferroelectric random-access memory (F-RAM) and integrated semiconductor products, has launched the FM6124 F-RAM-based event data recorder (EDR). The FM6124 continuously monitors state changes and stores them in the F-RAM. It is designed for use in the industrial control, medical, and metering markets. The EDR can perform in applications including activity, equipment, and environmental monitoring; maintenance scheduling; power-system management; automotive and industrial-automation event recording; vehicle and pedestrian traffic counting; and surveillance systems.
The FM6124 features 32 kbytes of F-RAM memory that can be used to store event records. Up to 24 kbytes of F-RAM can be configured to store event and user data. An on-chip real-time clock (RTC) with calendar enables time stamping of events and can function as a system clock and calendar. The RTC enables further analysis of captured data, which can be used by the system to generate alerts such as an equipment malfunction or a call for maintenance. The EDR includes 12 digital inputs that can be individually configured to trigger event recording on either a rising or a falling edge. The FM6124’s F-RAM memory can store up to 4000 event records. The device features an I2C interface that sustains communication speeds up to 100 kbps.
Base price: $7.50 each in quantities of 1000. Ramtron International, www.ramtron.com.
