Siemens Selects Freescale MRAM for Industrial Automation Touch-Screen Products
Freescale is providing non-volatile MRAM technology for an industrial touch-screen application developed by Siemens' Industry Automation division. Freescale's 4Mbit MRAM device has been integrated into Siemens' Simatic Multipanel MP 277 and MP 377 human machine interface (HMI) used in industrial automation systems.
Siemens chose Freescale's MRAM device for its HMI application because it provides an easy-to-use, non-volatile memory that maintains software-programmable logic controller (SoftPLC) process data for Siemens' HMI platforms without battery-backup. The user-programmable SoftPLC option enables the implementation of a comprehensive, expandable machine control system in a small form factor that helps reduce overall system cost. The multi-panels allow the integration of several automation tasks on a single platform using the SoftPLC.
