TMS320C10NL-25

Digital Signal Processor Dsp Overview

The TMS320C10NL-25 is a 16-bit digital signal processor from the TMS320C1x family, featuring a modified Harvard architecture. It operates with a cycle time of 160 ns and includes 144 words of on-chip data RAM and 1.5K words of on-chip program ROM. The device supports external memory expansion up to 4K words at full speed. Key computational units include a 32-bit ALU/accumulator, a 16x16-bit parallel multiplier producing a 32-bit product, and a 0-to-16-bit barrel shifter. It utilizes a single 5-V supply and functions within a commercial temperature range of 0°C to 70°C.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'NL' against official Texas Instruments documentation to confirm package type (typically PLCC) and temperature grade. Ensure compatibility with existing 5-V power supplies and 160-ns timing requirements in the target design.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring object-code compatibility with the original TMS32010 but needing faster 160-ns performance. Suitable for designs utilizing the microcomputer mode with on-chip ROM or microprocessor mode with external memory. Verify pinout compatibility if replacing older C10 variants.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C1x generation, which evolved from the first TMS320 DSP introduced in 1983. All C1x devices are object-code compatible with the TMS32010 core. The C10 variant serves as the foundational CPU for other C1x devices, offering basic I/O and memory configurations without the serial ports or coprocessor interfaces found in later models like the C17.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include TMS320C10-14 (280-ns cycle) or standard TMS320C10 (200-ns cycle). For higher performance, consider TMS320C15 or TMS320C16, though these offer different memory maps and package types.
