Application-specific standard product
An application specific standard product or ASSP is an integrated circuit that implements a specific function that appeals to a wide market. As opposed to ASICs that combine a collection of functions and are designed by or for one customer, ASSPs are available as off-the-shelf components. ASSPs are used in all industries, from automotive to communications. As a general rule, if you can find a design in a data book, then it is probably not an ASIC, but there are some exceptions.
For example, two ICs that might or might not be considered ASICs are a controller chip for a PC and a chip for a modem. Both of these examples are specific to an application (which is typical of an ASIC) but are sold to many different system vendors (which is typical of standard parts). ASICs such as these are sometimes called Application-Specific Standard Products (ASSPs).
Examples of ASSPs are integrated circuits that perform video and/or audio encoding and/or decoding.
