TMS320F241FN - 16-Bit 20MHz Flash DSP | Texas Instruments
部品番号: TMS320F241FN ✗ 生産終了TMS320F241FN 概要
A digital signal processor is a specialized microprocessor architecture optimized for filtering, signal transformation, control, and other mathematically intensive real-time operations. The TMS320F241FN sits within the broader hierarchy of fixed-point DSP controller, digital signal processor, embedded processor, and microcontroller. Its dedicated architecture allows control and signal-processing tasks to be executed without relying on a general-purpose host processor.
Key device characteristics include a 16-bit instruction width, 20 MHz operating frequency, and 16 KB of organized flash memory described by the distributor listing as 8K x 16. The verified product description also identifies a 5 V fixed-point DSP architecture, high-performance static CMOS technology, and a 50 ns instruction-cycle time for commercial and industrial grades. The integrated flash memory supports standalone control-system implementations without requiring a separate external program-memory device.
The architecture follows the TMS320C2xx execution model and is designed for embedded real-time signal processing. Compatibility with TMS320C25 source code allows qualified legacy algorithms to be migrated without a complete software rewrite, while TMS320C2xx object compatibility supports established software-component reuse. This combination makes the TMS320F241FN relevant to industrial motor control, digital power conversion, instrumentation, and embedded control systems.
Typical applications include digital motor control, industrial automation, power-supply control, communications signal processing, and measurement equipment. The 20 MHz processor rate and fixed-point architecture are particularly useful when deterministic execution, compact control loops, and direct access to embedded peripherals are more important than high-level processor performance.
Designers should verify the complete electrical limits, peripheral configuration, memory map, and pin assignments against the manufacturer datasheet before schematic capture. PLCC assembly also requires attention to thermal performance, board cleanliness, and socket or soldering process. The distributor data does not provide current unit pricing, inventory quantities, or lead times, so procurement planning should use a current authorized-distributor quotation rather than assumed values.
This product record consolidates the verified distributor identity, package, memory, clock, and source links while clearly separating unknown electrical and lifecycle details. It also documents why candidate parts that use a different package or a different processor architecture are not presented as drop-in replacements.

主な用途
TMS320F241FN の用途: 6 件s: Industrial Motor Control, Digital Power Supply Control, Industrial Automation Controller, Instrumentation and Measurement, Communications Signal Processing, Legacy Control-System Modernization.
Industrial Motor Control
The TMS320F241FN fits industrial motor-control prototypes that require deterministic fixed-point computation, a 20 MHz clock, and 16 KB of standalone flash memory. Its 16-bit TMS320C2xx core can execute control calculations at a 50 ns instruction-cycle rate, while source compatibility with TMS320C25 software may simplify migration from established industrial code. The device is positioned in the DSP-controller hierarchy rather than as a general-purpose MCU. Before committing to it, engineers must verify the PWM outputs, analog-to-digital converter channels, timer resources, input protection, and operating-temperature range in the full datasheet. A PLCC implementation also requires a reliable assembly process and adequate thermal design.
Digital Power Supply Control
The TMS320F241FN is applicable to digital power-control loops that benefit from rapid fixed-point execution and deterministic sampling and control functions. Its 20 MHz operating rate provides a 50 ns instruction-cycle time, while 16 KB of flash supports a self-contained control program. An engineer could use the processor to calculate compensation behavior and manage a power-conversion state machine, subject to confirmation of the device's PWM, ADC, timer, and comparator resources. The principal benefit is integrated real-time processing without a separate host controller; the main design constraint is that flash memory is limited to 16 KB, so code size, boot flow, and update strategy must be planned carefully.
Industrial Automation Controller
The TMS320F241FN can support compact automation and embedded control modules that combine signal processing with fixed-point control logic. Its 16-bit arithmetic and 20 MHz clock are appropriate for deterministic loops, and the 16 KB flash organization of 8K x 16 permits standalone program storage. TMS320C25 source-code compatibility may reduce effort when adapting qualified algorithms, while TMS320C2xx object compatibility supports reuse of compatible software objects. Deployment in a factory environment requires verification of the full electrical limits, I/O count, communications peripherals, temperature range, and EMC implementation. Its 68-pin PLCC package is mechanically distinct from modern QFN options, so existing industrial boards or planned socketed assemblies should be considered.
Instrumentation and Measurement
The TMS320F241FN is relevant to measurement equipment that must filter and analyze signals in real time while retaining a compact embedded architecture. The 16-bit fixed-point core processes sampled data efficiently, the 20 MHz rate yields a 50 ns instruction cycle, and integrated 16 KB flash supports a dedicated application without external program storage. A practical design would use verified ADC inputs, timer-based sampling, and serial or parallel communication outputs, but the supplied excerpts do not define those peripheral resources. Engineers should therefore treat the frequency and memory as confirmed strengths while checking the datasheet for converter resolution, acquisition timing, interface channels, and calibration requirements before finalizing the architecture.
Communications Signal Processing
The TMS320F241FN can be evaluated for embedded communications functions that require real-time filtering, modulation-related calculations, or control alongside a dedicated DSP engine. Its 16-bit fixed-point format and 20 MHz execution rate support deterministic arithmetic, while 16 KB of flash is sufficient for appropriately scoped standalone firmware. The suitability of the part depends on the required sample rate, filter order, framing protocol, memory depth, and serial interface; those details are not included in the supplied distributor excerpts. For new communications products, the designer should compare the TMS320F241FN against controllers with larger memories and current production status, and verify whether legacy TMS320C25 source compatibility provides a worthwhile software-reuse advantage.
Legacy Control-System Modernization
The TMS320F241FN is a logical candidate for selective modernization of equipment built around TMS320C25 software because the verified description states that it is source-code compatible with TMS320C25. This can reduce migration effort when the existing algorithm can be retained, while the TMS320C2xx core, integrated flash memory, and 20 MHz clock provide a defined upgrade path. Compatibility still does not guarantee that every peripheral, interrupt vector, timer setting, or board-level interface is unchanged. A replacement project should preserve the original toolchain and linker map where possible, run regression tests against real signals, and compare the target's electrical and pin requirements with the existing 68-pin PLCC footprint before modifying hardware.

- Deterministic fixed-point processing （vs General-purpose microcontroller alternatives)
設計ノート
Do not treat a same-core or source-compatible C2000 device as a drop-in replacement. The verified cross-reference describes TMS320F241PAG as a 64-pin TQFP alternative, whereas the target uses a 68-pin PLCC package. Any proposed substitute must be checked for identical pin numbering, power pins, ground distribution, peripheral multiplexing, memory organization, input levels, and output-drive characteristics before PCB substitution is approved.
Plan the PCB footprint around the confirmed 68-pin PLCC package, which measures 24.23 mm by 24.23 mm. Preserve access to all package leads for inspection, rework, and socket-based maintenance, and provide suitable thermal and copper-landing geometry under the device. Because the supplied data does not identify the exact lead pitch or pin assignments, the mechanical drawing and complete manufacturer pinout must be imported before layout release.
The verified listing identifies a 5 V supply, but it does not provide the complete operating range, I/O thresholds, absolute maximum ratings, or peripheral supply requirements. Design the power tree from the manufacturer datasheet rather than assuming every I/O can tolerate 5 V. Include local bulk and high-frequency decoupling, verify sequencing requirements, and account for startup current and any internally generated analog supply needs in the board-level budget.
The supplied excerpts do not publish power dissipation, junction-temperature limits, or package thermal resistance for the TMS320F241FN. Consequently, no defensible junction-temperature estimate can be made from the available data. Evaluate thermal performance using the actual processor duty cycle, I/O loading, ambient temperature, and PCB copper area, then apply the thermal values published in the full manufacturer datasheet.
コンプライアンス情報
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance. The commercial and industrial grade descriptions are product-temperature references and are not treated as AEC-Q100 qualification evidence.
