Or no smaller than 1. Therefore, our inventory can always meet customers needs, even including many obsolete part and hart to find part. At89c55131a have a professional logistics team and a professional logistics information platform, so we can deliver products safe and quickly.

Some parts, at89f5131a niche products or packages, and some manufacturers have big lead times, so even if a first production run can be met with existing stock, there may be logistical nightmares in the future.

Email Required, but never shown. List out all pin requirements, e. Depending on which microcontrollers you are familiar with, and your power and RF requirements, there would be a range of choices.

Anindo Ghosh 46k 7 84 There are 24 at89ca-um suppliers, mainly located in Asia. After analyzing all the above parameters, a decision that is not tightly tuned to the defined parameters often still makes sense. What formats are acceptable: Sign up using Email and Password. Second-source or minimum-rework code compatible alternatives At89c131a lower end ARM parts sometimes allow switching manufacturers and specific parts at889c5131a reasonably small effort Some compatible MCUs are drop in replacements for each other Sometimes code compatibility is good enough to permit entirely changing the product family without massive redevelopment, e.

What are the price constraints? Thanks for the info but I’m actually wanting to create a new transmitter key fob that can store a set of PRNG’s codes. Supplier Types Trade Assurance.

For a guaranteed single production run, even an obsolete part may be viable if available in new-old-stock.

Any items must be returned in their original condition to qualify for a refund or replacement. In rare cases,the strict at89c5131x clearances will make the delivery time a bit longer,please be patient.

Sample Order Free samples. Is there a simple mircocontroller in the market I can use? What is the minimum pin pitch the production process can use? For a product expected to see production over the next 10 years, a manufacturer’s commitment of part availability makes or breaks decisions What are the lead time constraints? Must the package support the use of a ZIF programming socket before insertion into production boards?

Arduino, Energiaswitching between AVR and Tiva-C may be viable I am sure some of the stalwarts on this site can add a large number of other parameters, but the above points are a good start.


Is 7mm by 7mm not small enough? For small volumes on a client-billable product, this may not be a constraint, but for huge volumes, a 1 cent price difference adds up to a fair bit.
