Identifying a suitable “small” microcontroller is a much-detested but essential step in many of my designs, so here are some of the typical steps. List out all pin requirements, e. About product and suppliers: Also, discount patterns for volume purchases vary mu between parts, even from the same MCU manufacturer What are the end-of-life constraints?
Your order is recognized as you are with full acknowledgement of product specs and respective policies. Must the package support the use of a ZIF programming socket before insertion into production boards? Any items must be returned in their original condition to qualify for a refund or replacement.

Anindo Ghosh 46k 7 84 Sign up or log in Sign up using Google. Is there a simple mircocontroller in the market I can use? Once all these parameters are defined, at899c5131a parametric search on the manufacturer’s site is generally the best way to narrow down the choices.
Second-source or minimum-rework code compatible alternatives The lower end ARM parts sometimes allow switching manufacturers and specific parts with reasonably small effort At89c51331a 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 is the minimum pin pitch the production process can use?
Even so, a careful study of the datasheets of shortlisted products is essential. Depending on which microcontrollers you are familiar with, and your power and RF requirements, there would be at89c5131 range of choices.
Thus, there are some designs where a at889c5131a smaller package or a simpler MCU would amply serve the purpose, but the NRE cost saved by reusing code from earlier projects makes it worthwhile to stick with one or the other of these.
Actually so would many other microcontrollers, so that deserves some research and perhaps a fresh question. What are the price constraints? Some parts, especially 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. In rare cases,the strict custom clearances will make the delivery time a bit longer,please be patient.
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.
