TMS320C10NL

Digital Signal Processor Dsp Overview

The TMS320C10NL is a 16-bit digital signal processor from the Texas Instruments TMS320C1x family, utilizing CMOS technology. It features a modified Harvard architecture with a 32-bit ALU/accumulator and a 16x16-bit parallel multiplier producing a 32-bit product. The device includes 144 words of on-chip data RAM and 1.5K words of on-chip program ROM. It supports external memory expansion up to 4K words at full speed. The standard cycle time is 200 ns, enabling operation at 5 MIPS. It operates on a single 5-V supply and is available in 40-pin DIP or 44-lead PLCC packages.

• Computer peripheral processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'NL' against the manufacturer's current production status, as this component belongs to an older generation (TMS320C1x). Confirm package availability in 40-pin DIP or 44-lead PLCC formats. Ensure compatibility with legacy design tools and object code requirements for the C1x architecture.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C10NL when a base CPU core with minimal on-chip memory is required for cost-sensitive designs. Compare cycle times: the standard version operates at 200 ns, while faster variants like the C10-25 offer 160 ns. Consider the C14 or C15 if expanded RAM, EPROM, or serial ports are needed instead of external memory reliance.

Digital Signal Processor Dsp Part Context

The TMS320C10 serves as the foundational CPU core for the entire TMS320C1x family. Introduced in 1983, it established the object-code compatible lineage of the first TMS320 DSPs. It provides the essential microprocessor functionality upon which subsequent devices like the C14, C15, and C17 build by adding peripherals such as serial ports, timers, and larger memory arrays.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the TMS320C10-25 (160-ns cycle) and TMS320C10-14 (280-ns cycle). For enhanced features, consider the TMS320C14 or TMS320C15, which retain core compatibility but add on-chip RAM, EPROM options, and additional I/O capabilities.
