First event-data recorder with integrated non-volatile F-RAM memory

The FM6124 Event-Data Recorder (EDR) IC from Ramtron provides a single-chip event-monitoring solution that generates system alerts to state changes and stores measured information in low-power non-volatile Ferroelectric RAM (F-RAM).

The FM6124 is similar to a Programmable Logic Controller (PLC), and delivers benefits such as simple device settings and data retrieval for easy system integration and rapid design-in. The device can be customised to monitor inputs other than edge-detected signals. Versatile operating modes include pulse-width monitoring to detect a preset minimum or maximum pulse width, as well as frequency monitoring.

The FM6124 includes 32kbyte of F-RAM memory, and allows 24kbyte to be configured to store event or user data. The on-chip Real-Time Clock (RTC) offers calendar time-stamps and recorded events, and is usable as a system clock and calendar.

The RTC enables broader analysis of captured data, upon which the system can act in a number of ways. Examples include issuing an alert to the problem or even calling for maintenance. These features are accessed via a high-speed I²C interface. The FM6124 can be installed away from the host system and closer to the equipment and/or sensors that it is monitoring.

 

FEATURES Stores up to 4,000 event records Virtually unlimited memory endurance 12 digital event inputs 16-bit non-volatile event counter Programmable 64-bit serial number

APPLICATIONS Industrial automation Environmental monitoring Vehicle/pedestrian traffic counting Equipment usage monitoring Maintenance scheduling
