What Does Connected Limited Device Configuration (CLDC) Mean?Connected Limited Device Configuration (CLDC) is a set of standards, libraries, and virtual-machine features that serve as the basis for APIs targeted at devices with very limited resources. A large number of feature phones, as well as some embedded systems, fall under this category of devices.
CLDC is one of two configurations under the Java Platform Micro Edition (Java ME). Compared to the devices supported by another configuration (called Connected Device Configuration), CLDC-supported devices have more constrained hardware resources, including RAM, screen size and resolution, and CPU.
CLDC can work with devices that are driven by 16-bit or 32-bit microprocessors/controllers. These microprocessors/controllers should have clock speeds of at least 16 MHz and available non-volatile memory of at least 160 KB for the CLDC libraries and the virtual machine, as well as 192 KB for the Java platform. In most cases, these devices are powered by batteries and support wireless connectivity.
