EP7312-CV-90

Microprocessors Overview

The EP7312-CV-90 is a System on Chip featuring an ARM720T processor with an ARM7TDMI core operating at 90 MHz. It includes 8 KBytes of four-way set-associative cache, an MMU with a 64-entry TLB, and 48 KBytes of on-chip SRAM. The device supports ultra-low-power operation with typical consumption of 108 mW at 90 MHz and less than 0.03 mW in standby. It integrates interfaces for SDRAM, LCD controllers, digital audio, and two UARTs with IrDA support.

Microprocessors Procurement Notes

Verify the specific suffix 'CV' against official documentation to confirm package type and temperature range. Confirm availability status as older Cirrus Logic components may be discontinued or subject to last-time buy notices. Ensure design-in compatibility with required memory and peripheral configurations before ordering.

Microprocessors Selection Notes

Select this component for designs requiring high code density through the ARM Thumb instruction set and integrated security features. Consider the 90 MHz variant when maximum processing performance is needed within the EP7312 family. Evaluate power requirements against the specified 2.5 V core and 2.5 V–3.3 V I/O operating ranges.

Microprocessors Part Context

The EP7312 belongs to the Cirrus Logic EP73xx series of highly integrated system-on-chip processors. These devices are designed to minimize external component count by integrating memory controllers, audio interfaces, and display drivers directly onto the silicon die alongside the ARM7 processor core.

Microprocessors Replacement Considerations

Consult official Cirrus Logic documentation for confirmed substitute part numbers. Verify pinout and functional compatibility if considering alternative microcontrollers from other manufacturers.
