EP9307 General Description

The EP9307 is one of a series of ARM920T-based devices.

The ARM920T microprocessor core with separate 16 Kbyte, 64-way set-associative instruction and data caches is augmented by the MaverickCrunch™ coprocessor enabling high-speed floating point calculations.

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.

A high-performance 1/10/100 Mbps Ethernet Media Access Controller (MAC) is included along with external interfaces to SPI, I2S audio, Raster/LCD, keypad and touchscreen. A three-port USB 2.0 Full Speed Host (OHCI) (12 Mbits per second) and three UARTs are included as well.

The EP9307 is a high-performance, low-power RISCbased single-chip computer built around an ARM920T microprocessor core with a maximum operating clock rate of 200 MHz (184 MHz for industrial conditions). The ARM core operates from a 1.8 V supply, while the I/O operates at 3.3 V with power usage between 100 mW and 750 mW (dependent on speed).
