STMicroelectronics ST10™ ST10F276, ST10F269, ST10F296 * Microcontrollers

UDE® Debug, Trace and Test solution for STMicroelectronics ST10™ ST10F276, ST10F269, ST10F296 *

The architecture of the ST10F269 combines the advantages of both RISC and CISC processors in a very well-balanced way. The sum of the features that are combined result in a high-performance microcontroller, which is the right choice not only for today's applications but also for future engineering challenges. The ST10F269 not only integrates a powerful CPU core and a set of peripheral units into one chip but also connects the units in a very efficient way. One of the four buses used concurrently on the ST10F269 is the XBUS, an internal representation of the external bus interface. This bus provides a standardized method of integrating application-specific peripherals to produce derivatives of the standard ST10F269.
