TMS320LC549PGE-80

Digital Signal Processor Dsp Overview

The TMS320LC549PGE-80 is a fixed-point digital signal processor from the Texas Instruments TMS320C54x family. It features a high-performance CMOS architecture with a maximum clock frequency of 80 MHz, delivering up to 64 million instructions per second (MIPS). The device integrates 128 kB of on-chip program memory and 28 kB of data RAM. Key architectural components include an 8-channel direct memory access controller, a multi-channel buffered serial port, and a hardware timer. Designed for low-power applications, it supports multiple voltage domains including 1.8 V core and 3.3 V I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'PGE-80' against the manufacturer's official datasheet to confirm the package type (typically LQFP-144) and temperature range. Ensure compatibility with system power requirements, specifically the 1.8 V core and 3.3 V I/O voltages. Cross-reference the part number with current production status notifications to avoid obsolete components.

Digital Signal Processor Dsp Selection Notes

Select this model when an 80 MHz clock speed is required within the C54x family. Compare against variants like the TMS320LC549PGE-40 or PGE-50 if lower power consumption at reduced speeds is sufficient for the application. Verify that the 128 kB program memory meets code size requirements without external memory expansion.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C54x series, a widely used 16-bit fixed-point DSP platform. The LC549 variant represents a low-power version optimized for battery-operated devices. It shares instruction set compatibility with other C54x processors, facilitating software migration across the family while offering distinct memory and speed configurations.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package may include other TMS320LC549 variants with different speed grades (e.g., -40, -50, -66). Upgrades to newer generations such as the TMS320VC5416 series offer higher speeds but require verification of pinout and peripheral compatibility.
