OVERVIEW
(cont.)
TheEP7311 is designed for 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.
One of its notable features is MaverickKey unique IDs.
These are factory programmed IDs in response to the
growing concern over securewebcontent 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 consist of two
registers, one 32-bit series register and one random 128-
bit register that may be used by an OEM for an
authentication mechanism.
Simply by adding desired memory and peripherals to the
highly integrated EP7311 completes a low-power system
solution. All necessary interface logic is integrated on-
chip.
