EP7311
High-Performance, Low-Power System on Chip
FEATURES
■ LCD controller
■ Full JTAG boundary scan and Embedded ICE
■ Integrated Peripheral Interfaces
■ Internal Peripherals
OVERVIEW
The EP7311 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 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
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.
