Product Summary

The EP7312-CVZ is a System-on-chip with SDRAM & Enhanced Digital Audio Interface. The EP7312-CVZ is designed for ultra-low-power operation. Its core operates at only 2.5 V, while its I/O has an operation range of 2.5 V–3.3 V. The device has three basic power states: operating, idle and standby. MaverickKey unique hardware programmed IDs are a solution to the growing concern over secure web content and commerce. With Internet security playing an important role in the delivery of digital media such as books or music, traditional software methods are quickly becoming unreliable. The MaverickKey unique IDs provide OEMs with a method of utilizing specific hardware IDs such as those assigned for SDMI (Secure Digital Music Initiative) or any other authentication mechanism.
