TMS320LBC52PJ

Digital Signal Processor Dsp Overview

The TMS320LBC52PJ is a digital signal processor from the Texas Instruments TMS320C5x family, fabricated using static CMOS technology. It features a powerful 16-bit CPU capable of executing up to 50 million instructions per second (MIPS). The device supports single-cycle instruction execution times of 50 ns, 40 ns, and 25 ns for 5-V operation, and 50 ns, 40 ns, and 25 ns for 3-V operation. It includes a single-cycle 16 × 16-bit multiply/add unit and addresses up to 224K × 16-bit external memory space. On-chip memory consists of 4K × 16-bit single-access SARAM and 1K dual-access DARAM. The component utilizes a 100-pin Quad Flat Package (PJ suffix) and incorporates IEEE Standard 1149.1 test-access port capabilities.

Digital Signal Processor Dsp Feature Summary

• Executes up to 50 MIPS with single-cycle 16 × 16-bit multiply/add operations
• Includes 4K × 16-bit on-chip SARAM and 1K dual-access DARAM
• Supports full-duplex synchronous serial port and time-division-multiplexed (TDM) serial port
• Features multiple phase-locked loop (PLL) clocking options and boundary scan support

Digital Signal Processor Dsp Applications

• Coder/decoder interface applications via full-duplex synchronous serial port
• Control operations utilizing the on-chip timer
• Data and program management through block moves and repeat instructions

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix required for the target operating voltage and clock frequency. Confirm package availability as the PJ suffix denotes a 100-pin Quad Flat Package. Ensure design safeguards are implemented to minimize risks associated with customer products and applications, as TI assumes no liability for application assistance or customer product design.

Digital Signal Processor Dsp Selection Notes

Select the TMS320LBC52PJ when a 16-bit DSP with moderate on-chip memory and parallel I/O interfaces is required. The device supports both 5-V and 3-V operation, offering flexibility in power supply design. Consider the available on-chip ROM boot loader if software initialization from external memory is not desired. Verify that the 100-pin package fits the board layout constraints compared to other C5x variants like the PQ or PZ packages.

Digital Signal Processor Dsp Part Context

The TMS320LBC52PJ belongs to the TMS320C5x generation of digital signal processors, which are based on the earlier TMS320C25 architecture. This family provides upward-compatible source code with ’C1x and ’C2x DSPs. The 'LC' designation indicates low-voltage operation, while the 'PJ' suffix specifies the 100-pin Quad Flat Package. These devices are designed for high-performance static CMOS processing with minimized power consumption.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package include the TMS320C52PJ for 5-V operation. For 3-V operation, the TMS320LC52PJ is the direct equivalent. Other members of the C5x family such as the TMS320C51 or TMS320LC51 offer similar architectures but differ in on-chip memory sizes and pin configurations.
