TMS320C10FNL25

Digital Signal Processor Dsp Overview

The TMS320C10FNL25 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 dedicated 16 × 16-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 FNL25 suffix indicates a 160-ns cycle time (5 MHz operation) in a 44-lead Plastic Leaded Chip Carrier (PLCC) package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm that the PLCC package style matches the target PCB footprint requirements. Ensure the 5-V supply voltage aligns with the system design constraints.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring object-code compatibility with the original TMS32010 DSP. Choose the 160-ns variant when higher throughput is needed compared to slower versions. Consider the PLCC package if surface-mount assembly is preferred over DIP formats.

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 serves as the foundational CPU model within this family, providing the base architecture expanded upon by subsequent models like the C14 and C15.
