Like the Cortex-M3 & M4, it is a 32-bit ARMv7-M core processor. I is said to use a six-stage superscalar pipeline. The ARM literature says that it will have highly flexible system and memory interfaces. Looking forward to seeing more details on that... (though of course it will lack a MMU). It lau…

ST Micro announced the first chip as well (The ARM Developer's Conference is next week...) [image] STM32F7 Series - STMicroelectronics ST's STM32F7 series features Arm Cortex M7-based high-performance 32-bit microcontrollers, delivering the maximum theoretical performance of the Cortex-…

Bummer there is no EEprom on the STMicro variant. Perhaps I'm not very bright, but other than SDMicro storage, I haven't found a good way to store homing constants (think positioning in motion control apps) or calibration data (think analytical sensors) when EEprom isn't present. I imagine everyon…

An external serial EEPROM is pretty easy to add, especially if you're already using I2C or SPI. A fair number of of the no-EEPROM chips have added features to the flash to make it more usable for the sorts of application that you describe. Separate protection bits and/or smaller page sizes for spec…

I don't believe EEPROM is compatible with 40nm technology, gate oxide isn't thick enough? Often at least one support chip would have EEPROM anyway, RTC, power management, etc etc.

MarkT, That's interesting info. Both Atmel and TI produce MCUs utilizing the Cortex-m4 core. The Atmel SAM4* MCUs, have no EEProm provisions. The Cortex-M4 is produced on the 65nm process node. To contrast, the TI TM4C1259 has 6k of EEProm. It will be interesting to see how TI addresses EEProm w…
