Q. Why don't you have a UPS shipping option in your shop?
A. We don't use UPS for shipping primarily because they charge exorbitant Customs Brokerage fees for cross-border Ground shipments. FedEx and postal services are much more reasonable.
Q. Why did Freescale discontinue the M68MOD912C32 and M68DKIT912C32 ?
A. These Freescale products are actually remarked versions of our NanoCore12 32-pin DIP module and Kit1. Freescale adopted them for the purpose of launching their 9S12C32 microcontrollers a few years ago. When the Restriction of Hazardous Substances (RoHS) legislation recently came into effect in the European Union, Freescale decided to drop these products from their lineup, as they are not RoHS-compliant. But both products are readily available from Technological Arts. Just click on the 9S12 Category and look for NanoCore12 or click here. Furthermore, these products are eligible for substantial educational and volume discounts. Contact us for more information.
Q. I heard that Freescale has discontinued many of their 68HC11 and 68HC12 microcontrollers. Is that true?
In the 68HC11 family, out of all the parts our products use or support, only the 68HC811E2 was discontinued. The OTP (one-time programmable) versions, such as the 68HC711E9 and 68HC711E20, are active parts, which now have an added letter "E" in the part number (e.g. MC68HC711E9CFNE2). UPDATE: the E9 has been discontinued, and part-numbering has dropped the letters "HC" so now the example p/n is MC68711E20CFNE2.
In the 68HC12 family, parts such as MC68HC912B32 were renumbered in the form MCHC912B32 (i.e. dropping the "68" prefix). A full part number would be something like MCHC912B32CFUE8 or MCHC912B32VFUE8. In the case of the 68HC812A4, they dropped the entire prefix "68HC" and the part number is now simply MC812A4CPVE8.
A great way to find out who has stock is to do a search on www.findchips.com. If you're having trouble finding the full part number, try searching with a substring (e.g. 812A4 or 912B32).
Another good place to find part numbers, of course, is at www.freescale.com. While you're browsing through parts, don't be put off by the "not recommended for new design" status you may see on many of the parts. That is simply meant to encourage large-volume customers to design with the latest and greatest part. In reality, the typical life-span of Freescale microcontrollers is 10 to 20 years. Don't forget-- the 68HC11 was introduced in 1987, and is still very active today.
Q. Why don't you provide Tech Support by telephone?
Q. Why don't you offer products based on MicroChip or Atmel (or brand "XYZ") microcontrollers?
A. Because we don't want to :o) We love the 68HC11 and it's later enhancements, and that is where our expertise lies. We are a small company, with a lot of products, and it wouldn't make sense to spread ourselves too thin. Besides, there are lots of products already on the market for those chips.
Q. Do you offer custom hardware or software design services?
Not at this time.
Q. I need some minor customization on a product you make. Is it possible?
Note that if you ask us to leave parts off, it will not likely result in a lower price (unless your quantities are high), because the cost reduction in parts is usually offset by the increased costs incurred in handling a production-line exception. The semi-custom board will need to be diverted from our usual assembly/program/test workflow and manually processed by a skilled technician.
