TMS320LC548PGE-80

The Texas Instruments TMS320LC548PGE-80 is a high-performance 16-bit fixed-point digital signal processor designed for demanding embedded applications. It features an advanced multibus architecture with three separate 16-bit data memory buses and one program memory bus, supporting efficient data flow.

Key electrical specifications include an 80MHz clock rate, a 3.3V operating voltage, and a 40-bit arithmetic logic unit (ALU) with a 40-bit barrel shifter and two independent 40-bit accumulators. The processor also boasts a 17x17-bit parallel multiplier for single-cycle multiply/accumulate operations and includes on-chip peripherals such as a PLL clock generator, TDM serial port, HPI, and a 16-bit timer.

This DSP is housed in a 144-LQFP package with surface mount mounting type. It operates within a temperature range of -40°C to 100°C (TC). The device offers 4kB of on-chip ROM and 64kB of on-chip RAM, with extended addressing modes for large external memory spaces.

With its robust feature set, including power consumption control and JTAG boundary scan logic, the TMS320LC548PGE-80 is suitable for various signal processing tasks in embedded systems.
