M6 Memory Emulators


M6 Memory Emulators are an obsoleated product and ATI can no longer guarantee the ability to support new builds or RMA repairs. While supplies last, there is a limited inventory of parts and units available for existing integrations.

Based on older/obsolete calibration methods there is no direct replacement for M6 Memory Emulators.

Please contact your local sales office for more information regarding alternative solutions, replacements, remaining stock, and other options.

M6 Memory Emulator Modules

Achieve typical measurement rates of 300 to 400 data items every 10msec with exact time stamp accuracy using ATI’s tailored M6 Memory Emulators for the calibration of Electronic Control Units (ECUs). This competitively priced, stand-alone solution with built-in USB interface provides full, plug and play compatibility without the need for any additional hardware or external modules. Memory Emulator implementations for 8-, 16-, and 32-bit applications and BGA or socketed versions are available.
Product Features:
  • M6 supporting the Freescale PowerPC MPC5xx Product Family
  • M6V supporting the Freescale MPC5500 and MPC5600, VertiCal compliant Product Family
