A PRACTICAL SOLUTION to CUSTOM LINEAR I.C.'s -- ALD's "FUNCTION-SPECIFIC" ASIC PROGRAM "FUNCTION-SPECIFIC" is ALD's standard cell approach to custom linear circuits with the standard cells being ALD standard products. It allows you to design with completely specified standard linear I.C.'s and implement your custom I.C. - or - go into production with standard I.C.'s and transition into your custom I.C. - with no redesigns - as your production volume increases. Standard Part = Standard Cell = Kit Part Easy to implement. Step I. Step II. Step III. Step IV. Step V. Step VI. Order your "Function-Specific" Design Kit. Design your circuit with ALD standard products. Breadboard and prove your design. Decide on the package and pin-out. Send your circuit to ALD for a quotation. Place order, wait 12 -16 weeks, and receive your "Function-Specific" Circuit. No I.C. design techniques or software to learn. A full custom, high performance ASIC Program. There is a nonrecurring engineering charge. All standard packages, including SOIC's and dice, are available. Hi Rel processing available.

Optional simulation models, macromodels and subcircuits are available. * Design and breadboard with completely specified, off the shelf, standard I.C.'s as you normally do. * Minimizes risk - proves your design works before committing to a custom chip. * If you're not sure your volume justifies a custom chip just yet, go into production with standard ALD linear I.C.'s and transition to a custom I.C. when it suits you -AND- without a major redesign. * Optimizes your surface mount program - use an SOIC package and combine your linear I.C.'s onto one chip. * FAST: 12-16 weeks is the normal lead time once your "Function-Specific" order is placed -AND- you don't have to spend weeks or months becoming an I.C. designer in order to develop your circuit. * Low power, low voltage, precision Silicon Gate CMOS - using ALD's precision ACMOS process - provides 5V linear I.C.'s that match-up with the 5V digital circuits you're using in today's low voltage, low power systems.

Standard pin counts are 8, 14, 16, 18, 20, 22, 24, 28, 40, 48, 54, 68 and 84. Special packages are available. * High reliability military processing is available, as is ALD's industrial enhanced reliability "A+" program. * New products (=standard cells) are continually being announced by ALD. Should your design require cells not currently announced, check with us to see if what we have coming fits in with your plans. In the event ALD's "Function-Specific" approach doesn't meet your needs, ALD will work with you on your "full-custom I.C."

A: No. An array is a chip filled with fixed transistors, diodes and passives - which you must design with and interconnect - following I.C. design rules and sometimes using specialized software and hardware. "Function-Specific" is a standard cell approach with defined I.C.'s (standard parts) you configure using your standard design practices, resulting in a completely custom chip. In "Function-Specific" you have completely characterized higher level building blocks (such as various operational amplifiers) that were carefully developed to be integrated. Q: What about critical nodes? Will my circuit work in chip form? A: ALD has already solved this problem. The critical nodes are within the devices themselves - inside the op amps, timers, comparators, etc. All the normal input, output, and power supply nodes are noncritical and designed to withstand parasitic stray capacitances. As a result, integrating a variety of devices on a single chip presents no particular problem - as long as the breadboard works. Q: Is "SPICE" available for simulation? A: ALD supports simulation models, subcircuits and macromodels. PSPICE with this simulation can be conducted by either a customer or by ALD personnel, as a supplement to the breadboard. Q: Why does it take 12-16 weeks? A: Because each I.C. is different and must have a unique, complete custom mask set generated, wafers fabricated and tested, units packaged, final tested, and shipped. Q: Can resistors and capacitors be integrated in a "Function-Specific" I.C.? A: Yes, resistors and capacitors can be integrated on your custom linear I.C. Q: Can I put in 1% precision resistors and different types of capacitors? A: No, but you can bring out the leads where you want them and place your precision passives off the chip. Q: Can digital circuits be put on a "Function-Specific" chip? A: Yes, contact ALD for a list of digital SSI and MSI level gates that are currently available in the ALD "Function Specific" digital library. Q: Are diodes available on chip? A: You can use the MOSFETS in a diode-connected configuration. Q: Can I have isolated circuits on one chip? A: There are typically 120dB isolation between circuits. Q: How much does it cost? A: Since it is a full custom program, it depends on the complexity of the circuitry involved. There are two cost components. The first is a one time, nonrecurring engineering cost for setting up and implementing the project. The second component is a unit cost, which depends on the complexity, packaging, testing, and volume of the ASIC chip. An I.C. chip usually costs much less than buying the individual parts and assembling them onto a circuit board.
