Issue
How to determine if the IOU modules neuron chip is manufactured by Toshiba or Motorola?
Product Line
Andover Continuum
Environment
- Continuum Cyberstation
- I/O modules (All modules affected except the AC-1 Plus, VT-1, Infistat, and LC-1)
Cause
Up-revving I/O modules to new firmware and there are 3 types that have been used, Motorola, Toshiba and the most recent Cypress neuron chips. The program ID can help determine which neuron is in the IOU module to select the correct firmware.
Resolution
To determine the chip type, look at the Program ID using the object editor or a list view. The second digit or position of the second number of the Program ID is the chip set indicator. If the second digit is 2, the I/O Module has a Toshiba chip. If the second digit is 1, the I/O Module has a Motorola or if shipped after 2014 a Cypress chip.
See example of object editor below:
***** Note: The image above doesn't show the Cypress information. a 1 could be Motorola(old) or Cypress (new). If the flash revision is 21 the it is the most recent flash version for the Cypress chip. The IOU modules that could have the Cypress chip are AC-1(Not Plus), A0-4,DI-8,DM-20, D0-4, D0-6, MI-6, UI-8.
Motorola or Cypress
Ui8s that have an 11 in the second position of the ProgramID are either Motorola or Cypress chips.
The modules with ProgramID 11 in position 2 and firmware version 11 in position 4 of the ProgramID are Motorola and 11 is the most up-to-date version.
The modules with 11 in the 2nd position of ProgramID and firmware version 21 in position 4 of the ProgramID are Cypress chips.
I have not seen a separate firmware version 21 file for the Cypress chip on Exchange or anywhere. 21 is the most up-to-date version and was shipped with those modules.
The email we found indicates that since the Cypress chip was a direct replacement for the Motorola chip they used the same number (1) in the 2nd position of the ProgramID (instead of using 3).
To summarize the most up-to-date firmware versions for the Ui8:
Motorola: 11
Toshiba: 20
Cypress: 21
There is an old TPA that describes this in detail. You can download the TPA Technical Bulletin 1041 - Continuum IO Modules Now Using the Toshiba Neuron Chip from The Exchange Download Center.
