Sun offers Java SE for Embedded products in both binary and source offerings under an innovative licensing model. Development is free, but royalties are required upon deployment on other than general purpose systems (for details see license). Platforms available for embedded use include not only standard Java SE platforms but also platforms that are exclusive for the embedded market. In all cases, the products offered are fully Java SE compliant -- which enables you to reuse any Java code from other platforms or products without having to go through porting, recoding and test cycle.

Custom embedded platforms - for embedded devices having approximately 32MB or more for Java.

Sun-standard platforms - for devices having at least 70-80MB for Java.
