You are just three easy steps from designing your own chip


An Example Request From a Customer
Hello,
The project I am working on needs to be able to set off an alarm if it's tigger input goes LOW for more than 10 seconds but NOT more than 11. I have already built the alarm circuit, but still need a chip which has one input for the trigger and one output to connect to the alarm. I would like to purchase two identical chips for backup purposes. Thanks in advance.

Hello Robert,
Thank you for your request. Before we can give you an accurate quote we need to know how much deviation your values of 10 and 11 seconds can tolerate. For example, would 10.01 seconds and 10.99 seconds be acceptable?
Hope to hear from you soon,

ROBERT:
Hi,
Sorry for not being specific. The times don't have to be too exact. The range would still be OK if it were 9.5 seconds to 10.5 seconds but not much further. Hope this helps.
Thank you,
Robert

Hello Robert,
Thank you for the update. We can implement your design using a low cost microcontroller, this way you will save money on your second purchase. The one time design cost will be $50.00 plus the cost of two chips $20.00 and the shipping and handling charge of $10.00. So the final cost after tax is $86.60. You can use the form below to pay using most major credit cards. Once payment is received we will begin work on your chip and e-mail you when completed.
Thank you for your interest in Custom Chips,
