ICS 331-L Kit

The following parts are required for projects 5 and later. One set of these is needed for each lab team or lab group, or for each individual who is not part of a lab team. 1x or 2x means one or two of each of the parts should be obtained.

Unless otherwise specified, all components should be available from Digikey. The components not available from Digikey should be available from Jameco Electronics, as indicated. The suppliers indicated are only suggested -- any other supplier would be fine.

• 2x, 74AC00 14-pin DIP, quad 2-input NAND, $0.36 each/$0.72 total.
• 2x, 74AC02 14-pin DIP, quad 2-input NOR, $0.40 each/$0.80 total.
• 2x, 74AC04 14-pin DIP, hex inverter, $0.36 each/$0.72 total.
• 2x, 74AC08 14-pin DIP, quad 2-input AND, $0.40 each/$0.80 total.
• 2x, 74HC10 14-pin DIP, triple 3-input NAND, $0.40 each/$0.80 total.
• 2x, 74AC32 14-pin DIP, quad 2-input OR, $0.36 each/$0.72 total.
• 4x, SPDT toggle switches. Many possibilities available, including from Jameco part number 26315CD, $1.29 each/$5.16 total.
• 1x, NE-555, 8-pin DIP, timer, $0.40.
• 1x, 22uF-capacitor. Many possibilities available, including Digikey part number399-1318-ND, $0.88.
• 2x, 74LS109 16-pin DIP, dual J-K flip-flop with positive triggering, available from Jameco, $.29 each/$0.58 total.
• 1x, DS1225AB 28-pin DIP, 8Kx8 non-volatile RAM, $14.71.
• 1x, 74189 28-pin DIP, 16x4 volatile RAM, available from Jameco, $3.99.
• 1x, 74AC163 16-pin DIP, 4-bit synchronous counter, $0.56
• 2x, 74AC244 20-pin DIP, 8-bit tri-state buffer/driver, $0.50 each/$1.00.
• 1x, 74LS181 24-pin DIP, 4-bit ALU, available from Jameco, $1.25.
• 3x, 74HC194 16-pin DIP, 4-bit register, $0.48 each/$1.44 total.
• 2x, PIC 12F675 8-pin DIP, microcontroller, $2.30 each/$4.60 total.

The total cost for the required parts is 39.13, plus shipping and handling. You may obtain these parts for yourself if you so choose, from the vendors indicated or from anyone else, as long as you buy compatible circuits (from any 74- or 54-family) and obtain them in time for the projects -- the parts for project 5 must be available by Monday, October 20th.

If you prefer, you may combine with other teams to make a bulk purchase. The instructor is willing to coordinate this -- as a service to the class (and to make things simple), the instructor will pay the shipping costs. If the benefits from bulk discounts should exceed the shipping costs (which is very unlikely), any excess money will be returned to the students. In order to participate in this option, you must make out a check for $38.63 to E. Biagioni and give it to the instructor no later than class time on Wednesday (be sure your check clearly includes your last name).

There are also some optional parts you may order if you so choose. In particular, projects 6 and 7 will be to design and build a 4-bit CPU. Should you wish to instead build an 8-bit CPU, you will need the following parts in addition to the ones above:

• 1 additional DS1225AB 28-pin DIP, 8Kx8 non-volatile RAM, $14.71.
• 1 additional breadboard, probably part number 20811CD from Jameco Electronics, $31.95.
• 1 box for parts -- I have chosen a stack-on 10-compartment box, purchased at Sears for $2.99+tax.

This last breadboard might also come in useful if one of your team might wish to build your own digital circuit at some time in the future after the class is over.

Again, if you wish to order these optional parts on your own, that is fine. If you wish to go through the instructor and order these parts, please make out your check for the total price of $85.29 (or $70.58 if you want the breadboard but not the memory).

Any feedback and suggestions are welcome.
