TMS320F241FNS - 16-Bit 20MHz DSP with 16KB Flash | Texas Instruments
MPN： TMS320F241FNS ✓ 啟用中TMS320F241FNS 概覽
A digital signal processor is a specialized microprocessor architecture optimized for repetitive mathematical operations such as filtering, Fourier analysis, control-loop calculations, and waveform processing. Unlike a general-purpose microcontroller, the TMS320F241FNS places multiply-accumulate operations, dedicated memory interfaces, and interrupt-driven peripherals around a highly parallel fixed-point CPU core. The 50 ns instruction cycle time listed for the TMS320F241 family supports predictable control-loop execution at a 20 MHz system clock.
Key device characteristics include 16 KB of flash memory, a 5 V supply, a 16-bit arithmetic datapath, and compatibility with the TMS320C2xx instruction set and development environment. The flash-based configuration consolidates program storage on the device, while the PLCC package provides a leaded, socket-compatible mechanical option for industrial control equipment and legacy upgrades. The package measures 24.23 mm by 24.23 mm according to the distributor listing.
TMS320F241FNS is suitable for motor-control loops, digital power conversion, industrial data acquisition, communications front ends, and embedded audio or measurement systems. Its fixed-point architecture allows designers to implement deterministic filters and control algorithms without floating-point hardware. The C2xx-compatible instruction set also supports source-level migration paths from earlier TMS320C25-family designs, while the flash-memory version simplifies standalone system deployment.
When designing a new board, verify the complete pin configuration, peripheral multiplexing, and clocking requirements in the manufacturer datasheet before layout release. The 68-pin PLCC footprint is not interchangeable with leaded PQFP packages, so socketed legacy systems and new SMT designs require different PCB land patterns. This page consolidates the device specifications, drop-in replacement candidates, and design guidance engineers need when planning a controlled substitution or repair.

典型應用
TMS320F241FNS 適用於 6 應用s: Industrial Motor Control, Digital Power Conversion, Industrial Data Acquisition, Communications Signal Processing, Measurement and Instrumentation, Embedded Audio Processing.
Industrial Motor Control
The TMS320F241FNS fits deterministic digital motor-control loops because its TMS320C2xx core executes 16-bit fixed-point instructions with a 50 ns cycle time at a 20 MHz clock. The 16 KB flash configuration stores control code and tables on the device, while the 68-pin PLCC footprint matches legacy industrial controller hardware. A PWM-based motor drive can use the timer and interrupt resources for current sampling and duty-cycle updates. Before layout release, confirm PWM, capture, ADC, and digital I/O multiplexing in the datasheet because the 68 PLCC leads are heavily multiplexed. Verify that the selected temperature grade and legacy PLCC socket support the operating environment.
推薦
Digital Power Conversion
The TMS320F241FNS is appropriate for digital power-conversion controllers that calculate compensation terms and drive a switching stage through deterministic PWM outputs. Its 50 ns instruction cycle provides a 20 MHz execution basis for control-law updates, while 16-bit fixed-point arithmetic supports filter and compensator implementations without floating-point hardware. The 5 V supply and 68-pin PLCC package suit established industrial power-control boards. Confirm timer resolution, PWM dead-band support, analog-interface requirements, and pin multiplexing for the chosen topology. Use the datasheet electrical characteristics to set switching-node isolation and define the control-loop update rate.
推薦
Industrial Data Acquisition
The TMS320F241FNS can serve as the fixed-point processing core in an industrial acquisition system that performs filtering, scaling, and real-time spectral analysis. Its 16-bit datapath processes sampled data at a 20 MHz maximum clock, and the on-chip 16 KB flash consolidates program storage for standalone operation. A practical design can pair serial or parallel converters with digital filters, then pass results to a host processor. Pin assignment must be reviewed carefully because communication ports and general-purpose I/O share package leads. Confirm converter interface timing, interrupt latency, and memory-use requirements in the manufacturer datasheet before fixing the board layout.
推薦
Communications Signal Processing
The TMS320F241FNS is suitable for embedded modulation, filtering, and packet-processing functions where fixed arithmetic and predictable timing are central requirements. The TMS320C2xx core operates with a 50 ns instruction cycle at 20 MHz, enabling repeated multiply-accumulate-heavy filtering operations without a floating-point unit. Its 16 KB flash supports a self-contained communications controller, and the 68-pin PLCC package is common on established telecom and industrial control boards. Verify the availability and multiplexing of serial ports, timer pins, and interrupt sources for the selected protocol. Keep clock routing and switching supplies away from sensitive analog and communication interfaces.
推薦
Measurement and Instrumentation
The TMS320F241FNS can implement real-time measurement functions such as digital filtering, peak detection, calibration tables, and fast Fourier transform processing. Its 16-bit fixed-point architecture and 20 MHz clock are well matched to instruments that must return processed data within a fixed sampling interval. The flash-based TMS320F241FNS also simplifies firmware updates and standalone operation in laboratory or field equipment. For a new design, verify whether the application requires external RAM, and allocate the on-chip flash strictly for code and constants if no external memory interface is available. Use the datasheet pin table to assign display, communication, and measurement-control interfaces.
推薦
Embedded Audio Processing
The TMS320F241FNS can perform fixed-point filtering, mixing, and effects processing in an embedded audio system that prioritizes deterministic timing over general-purpose software flexibility. Its 50 ns instruction cycle supports tightly bounded sample-processing routines, while 16 KB of flash holds firmware and small coefficient tables. The device is especially relevant for upgrading legacy audio-control hardware built around the 68-pin PLCC footprint. Confirm serial audio-interface availability, sample-rate requirements, and external memory needs before assigning the design. If the system also handles network control, add a dedicated communications interface rather than stretching the DSP's multiplexed peripheral pins.

主要差異化特點
- Maintains the legacy 68-PLCC mechanical platform while providing flash-based program storage (對比TMS320F240PQS)
- Deterministic 20 MHz fixed-point execution for legacy control upgrades (對比TMS320F206PZA)
- Family-level source compatibility reduces legacy migration effort (對比TMS320F241FNSR)
設計說明
Design the board around the 68-lead PLCC footprint and preserve the manufacturer's lead pitch and solder-joint geometry. The device is not land-pattern compatible with PQFP or QFP packages, so an SMT conversion requires a new footprint, pin mapping, and thermal review. For repair-oriented designs, verify socket availability and pin-1 orientation before release because a mechanically similar footprint does not eliminate pin-function risk.
Route the device clock from a low-noise source and keep the clock trace short, continuous, and isolated from switching nodes and high-current power paths. Provide the required bypass capacitors at the supply pins with short ground returns, and follow the datasheet placement recommendations. Because several PLCC leads serve multiplexed peripheral functions, assign pins only after finalizing clocking and system-level operating modes.
Do not treat every C24x-family order code as an automatic substitute. Verify the exact MPN suffix, temperature range, silicon revision, qualification status, flash contents, and peripheral pin multiplexing before replacing a TMS320F241FNS in a deployed controller. Also confirm that the original firmware does not depend on device-specific peripherals or reserved locations outside the shared TMS320C2xx execution environment.
