Siemens AG has developed an industrial touchscreen human machine interface (HMI) application using magnetoresistive RAM (MRAM) technology supplied by Freescale Semiconductor Inc.

The companies said the 4Mbit MRAM, the first to be commercially available according to Freescale, has been integrated into Siemens Automation Division's Simatic Multipanel MP 277 and MP 377 HMI.

Siemens said it chose Freescale's MRAM device as it provides an easy-to-use, non-volatile memory that maintains software-programmable logic controller (SoftPLC) process data for its HMI platforms without the need for battery-backup.

The SoftPLC option will allow the implementation of an expandable machine control system in a small form factor that will help reduce overall system cost. The multipanels allow the integration of several automation tasks on a single platform using the SoftPLC.

Freescale's MRAM technology provides significant benefits, ranging from non-volatility to fast read/write capabilities, for rugged applications such as Siemens' industrial automation systems, said David Bondurant, MRAM product manager at Freescale Semiconductor. Our customers and their end users demand highly reliable memory products that are designed for critical applications.
