Micro-controller selection

Joseph Joseph

Hi there,

I need to select a micro-controller for our company's new project.

These are the requirements

16 to 32-bit MCU
64 GPIO minimum
Flash 1MB
RAM 64KB
Clock Frequency 100MHz
2 x CAN bus
SCI
Timers
Aerospace application
Temp: -40 to +125
No floating point
Able to procure part for the next 10 years or more.
Previously used in Automotive/Airborne application
Low power
Size and packaging
Cost
Certification kit – code coverage with the compiler and multievent profiler.

Anybody have any suggestion. TI website doesn't carry all the information, and it is very difficult to get into their application engineers fort.

Thank you.

Suggest you take a look at the Hercules devices.

Hi Joseph,

As Brandon suggests, it sounds like the Hercules TMS570 product line could be a good fit for you. Here is the overview page: http://www.ti.com/lsds/ti/microcontroller/safety_mcu/tms570_arm_cortex-r4/overview.page

This product line is designed targeting compliance for the IEC 61508 and ISO 26262 functional safety standards. Safety manuals and analysis reports are available today and component level certifications are pending for most devices in the family.

I suspect the closest fit will be in our TMS570LS11x/12x family. This product family includes"

16/32b CPU (ARM Cortex R4F)
~60 GPIOs (PGE package) or ~100 GPIOs (BGA package)
~1.25 MB flash + 64kB EEPROM emulation flash
128kB or 192kB SRAM
180 MHz CPU clock frequency
3x CAN bus
2x SCI
2 programmable timers (NHET) with ~40 channels plus dedicate motor control timers
Targeted for automotive/aerospace/rail transportation
Temp -40C to 125C ambient
Long term supply available
Used in automotive/aerospace/rail today, platform used in automotive high volume for 20+ years
Power dependent on use case
337 BGA or 144 PGE packages available
Cost - dependent on volume and part number
A compiler qualificaiton kit is available for the TI compiler : http://www.ti.com/tool/safeti_cqkit

Karl
