Q. I am new to the MCS 96 family and would like some basic technical information on the peripherals available on the MCS 96 devices.
A. Back to Basics documents are just for you. There are several Back to Basics documents available on the different MCS 96 peripherals. These documents explain the peripherals in easy-to-understand terms and include sample programs to help you design with the 196. The following documents are available:

Q. I have been using the 8XC196KB for years and I would like to migrate to the Extended Addressing parts (8XC196NT/NP/NU). Are there any documents to help make this transition?
A. Yes, there are a few documents that you should order from literature to help with this migration.
Document TitleLit. Order #Description
AP-714: Converting from the 8XC196KB/KC/KD to the 8XC196Nx Family272625This document includes a comparison of the registers and pins, describes several memory considerations, and discusses the differences between many of the peripherals.

Q. What are the complete order numbers for the CAN devices?
A. The part numbers for the CAN devices are:
Part Number Description
AN82527Controller Area Network Chip, 44-ld PLCC
AS82527Controller Area Network Chip, 44-ld QFP
AN87C196CAMCS 96 Controller with Integrated CAN, 16MHz, 68-ld PLCC
AN87C196CA20MCS 96 Controller with Integrated CAN, 20MHz, 68-ld PLCC
AN87C196CBMCS 96 Controller with Integrated CAN, 16MHz, 84-ld PLCC, 1MB addressability

AS87C196CBMCS 96 Controller with Integrated CAN, 20MHz, 100-ld QFP, 1MB addressability

Q. Are there any development tools available for the 196CA and 196CB?
A. The Dearborn Group makes evaluation boards for these products . They also offer training courses on the CAN Protocol. Their phone number is (810) 485-2080.

Q. Is there any information available on the 8xC198?
A. The 8xC198 is similar to the 8xC196KB, but with an 8-bit external bus. Use the 196KB User's Guide, order #270651. The differences between the 198 and the 196KB are in the datasheets, #270815 for the 80C198 and 83C198 and #272034 for the 87C198.

Q. Is there any information on the 8xC194?
A. This product has been discontinued. This product was an 8xC198 without the A/D Converter, so the suggested alternative is to use the 198 and just disable the A/D Converter. If you would like the datasheets for this controller, order literature #270815. The 194 Uses the 8xC196KB User's Guide, which is order #270651.

Q. My emulator works with my code, but the actual part doesn't.
A. See faxback #2190, which will answer the majority of problems of this type.

Q. I am using the 8XC196NT and my design works with the emulator, but when I replace the emulator with the chip, I don't get a WR# signal.
A. Be sure that the WR# signal is initialized correctly. The following registers should be programmed:
P5_DIR.2 = 0 to initialize as output
P5_MODE.2 = 1 to initialize as special function pin

Q. The target board only has one serial port, which is used to connect to the PC. How can I actually use the serial port in my design?
A. You can run the target board in standalone mode, which is fairly easy to do. This can be done with only a few alterations in your code and by changing one jumper on the board. See faxback #2352, which outlines how this is done.

Q. Do any 196's come with erasable ROM (EPROM)?
A. No, none of the 196's currently come in a ceramic package that have a window which would allow you to erase the EPROM. Many 196's come with OTPROM onboard. See the family line card, faxback #2591, for a listing of these.

Q. Are there any development tools available for the 196 microcontrollers?
A. Intel makes evaluation boards for most of the 196's, but we no longer make compilers, assemblers or emulators. See our development tools line card, faxback #2623, for a listing of third party vendors who make these tools.

Q. Is there a low voltage 196?
A. Yes, the 196NP has a low voltage version (3V at 14MHz.) The part number is x80L196NP or x83L196NP, where x is the package type.

Q. I'm looking for the pinout for a 196 microcontroller.
A. The pin descriptions and locations are on the individual datasheets for each microcontroller. You can order these individually, or all of them are contained in the Embedded Microcontrollers databook, literature #272646.

Q. I'm looking for the footprint, or physical dimensions of the package of a 196 microcontroller.
A. This information is in the Packaging Book, literature #240800. Look under the type of package that you have for the mechanical drawings and dimensions of that package.

Q. Is there any sample code anywhere that would assist me in writing my code?
A. Try the apbuilder software! This software is helpful in understanding the part better, and it will generate code for you in either Assembly or C. You can either download apbuilder off our BBS system or order it through the literature department, #272216. Other places to look for sample code are the user's manuals and the evaluation board user's manuals. The Back to Basics faxback documents also contain some good code.

Q. Speed is important to me. What is the fastest 196 available?
A. The 80296SA comes in both 40 and 50 MHz versions.
