OMAP3530ECUS

Overview

The OMAP3530ECUS is a specialized application processor from Texas Instruments, featuring a dual-core architecture with an ARM Cortex-A8 and a TMS320C64x DSP. It operates within a voltage range of 985 mV to 1.35 V and supports maximum clock frequencies of 430 MHz for the ARM core and 600 MHz for the DSP. The device includes 16 kB L1 instruction and 16 kB L1 data cache for the ARM core, alongside 32 kB L1 instruction and 80 kB L1 data cache for the DSP. It utilizes a PBGA-423 package and functions reliably between -40°C and +105°C.

Procurement Notes

Verify component authenticity by checking the manufacturer marking against official datasheet specifications. Ensure the PBGA-423 package matches design requirements. Confirm RoHS compliance status through the manufacturer's documentation. Validate that the specific suffix corresponds to the intended performance grade and temperature range before integration into production systems.

Selection Notes

Select this component when both general-purpose computing and high-performance digital signal processing are required in a single unit. The dual-core design allows for efficient task distribution between the ARM processor and the DSP. Consider the PBGA-423 footprint and thermal characteristics during PCB layout. Ensure power supply designs accommodate the specified voltage range and current demands of the integrated cores.

Part Context

This part belongs to the OMAP3530 series of specialized application processors manufactured by Texas Instruments. These devices are engineered for multimedia and communication tasks requiring significant computational power. The ECUS suffix typically denotes specific packaging or quality grades within the broader product family, distinguishing it from other variants like the OMAP3503 or OMAP3515.

Replacement Considerations

Direct substitutes include other OMAP35xx series processors such as the OMAP3503ECUS or OMAP3515ECUS, though core configurations differ. Verify pin compatibility and software support before swapping. No direct cross-model functional equivalents exist outside the OMAP35xx family due to unique architectural combinations.
