TMS320LC545APBK-66

Digital Signal Processor Dsp Overview

The TMS320LC545APBK-66 is a fixed-point digital signal processor based on the enhanced C54x DSP core, manufactured by Texas Instruments. It operates at a maximum clock frequency of 66 MHz and features 16-bit architecture with 80-bit arithmetic precision. The device integrates 192 KB of on-chip program/data memory (SARAM) and includes an external memory interface supporting up to 4 MB of address space. Key peripherals include two serial ports, four general-purpose I/O ports, and a McBSP for serial communication. Packaged in a 256-pin PBGA, it supports low-power modes and is designed for high-performance audio and communications applications.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C54x family of 16-bit fixed-point DSPs. The 'LC' suffix typically denotes low-power variants within this lineage. The PBK package indicates a Plastic Ball Grid Array configuration. This specific model represents a mature generation of DSP technology focused on efficient algorithmic execution rather than floating-point operations.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements may be limited due to package and speed variations. Compatible alternatives within the same family include the TMS320LC5402 or TMS320VC5402 series, though verification of memory size and peripheral availability against the original design requirements is essential. Consult Texas Instruments documentation for specific cross-reference compatibility.
