TMS320F241FNA - 16-Bit 20MHz C24x DSP | Texas Instruments
Référence : TMS320F241FNA ✗ Fin de vieTMS320F241FNA Présentation
A digital signal processor is a programmable semiconductor optimized for arithmetic-intensive operations on streams of data. Its hardware and instruction architecture are designed to execute filtering, control, and signal-transformation algorithms efficiently. Within the product hierarchy, the TMS320F241FNA is a C24x fixed-point DSP, part of the C2xx family, and a member of Texas Instruments' embedded signal-processing portfolio.
The principal features include a 16-bit fixed-point processing core, a 20 MHz clock rating, and 16 KB of embedded flash for program storage. The 8K x 16 organization provides 8,192 16-bit program words. This combination makes the controller suitable for embedded motor-control, industrial automation, communications, and measurement systems where deterministic arithmetic and local nonvolatile program storage are useful.
The C2xx core uses a modified Harvard organization that separates program and data access. According to the Texas Instruments TMS320F241 datasheet, this separation allows instruction fetches and operand access to occur in parallel, improving computational concurrency compared with a shared-memory architecture. The device is identified as a fixed-point processor operating from a 5 V supply, positioning it for conventional embedded control rather than low-voltage portable systems.
Typical uses include digital motor controllers, programmable logic controllers, industrial equipment, communications interfaces, instrumentation, and embedded signal-processing modules. In these systems, the DSP can implement digital filters, feedback loops, motion algorithms, or protocol processing while retaining firmware in its internal flash. The 68-pin PLCC package provides a substantial pin count for external memory, host-interface, control, and peripheral connections.
Designers should confirm the exact peripheral pin assignment, electrical limits, and timing requirements against the Texas Instruments TMS320F241 datasheet before finalizing a PCB. Because the package uses exposed leads on a relatively large 24.23 mm square body, connector and assembly planning should account for lead pitch, orientation, thermal exposure, and available board area rather than treating the part as a compact leadless package.
This product page combines the key architecture, package, memory, and operating details with practical application guidance, sourcing questions, and replacement analysis. It is intended to help engineers confirm device suitability, plan the board, and identify whether a verified same-package replacement exists before committing the legacy C24x design to production.

Applications typiques
TMS320F241FNA convient pour 6 applications: Digital Motor Control, Industrial Automation Controller, Communications Interface, Embedded Instrumentation, Programmable Logic Control, Audio Signal Processing.
Digital Motor Control
The TMS320F241FNA suits digital motor-control loops that require deterministic fixed-point arithmetic and local firmware execution. Its 16-bit C24x core operates at 20 MHz and delivers up to 20 MIPS, providing computational capacity for feedback control, digital filters, and timing functions. The 16 KB flash can retain control firmware without a mandatory external program-memory device. Designers should assign motor-control peripherals, protection inputs, and external interfaces from the official pin table, then verify timing and electrical limits against the Texas Instruments datasheet before connecting power-stage circuitry.
Recommandé
Industrial Automation Controller
The TMS320F241FNA can serve as the arithmetic engine in industrial automation equipment that combines sequential control with real-time signal processing. Its 20 MIPS fixed-point throughput supports proportional-integral loops, filtering, and supervisory control functions, while the industrial temperature grade supports use in industrial environments. The 68-pin PLCC offers access to the device's control and peripheral signals, but engineers should confirm the required interface set and unused-pin treatment directly from the manufacturer datasheet. Firmware partitioning must also remain within the 8,192-word flash map.
Recommandé
Communications Interface
TMS320F241FNA is appropriate for embedded communications tasks where filtering, packet processing, or signal analysis must execute predictably alongside a control function. The modified Harvard core separates program and data paths, allowing instruction fetches and operand access to proceed concurrently, which supports efficient fixed-point algorithms. Its 20 MHz clock and 16 KB flash provide a compact execution and storage platform for dedicated interface modules. Board-level integration should preserve the C24x bus and peripheral mapping, and protocol timing should be validated under maximum bus and interrupt load rather than inferred from clock speed alone.
Recommandé
Embedded Instrumentation
The TMS320F241FNA fits embedded measurement modules that perform signal conditioning in firmware, including digital filtering, calibration calculations, and nonlinear correction. Its 16-bit fixed-point arithmetic and 20 MIPS throughput support deterministic processing of sampled data, while 16 KB of embedded flash holds compact control and measurement routines. The 5 V operating supply matches conventional industrial instrumentation where appropriate. Designers should allocate code and data carefully, verify peripheral timing against the datasheet, and preserve the documented PLCC footprint and pin assignments when updating legacy equipment.
Recommandé
Programmable Logic Control
TMS320F241FNA can implement programmable logic control where deterministic execution, arithmetic processing, and compact embedded flash storage are required. The C24x processor supports both control sequencing and fixed-point calculations, allowing one device to combine machine logic with signal conditioning or closed-loop functions. Its 20 MHz clock and 20 MIPS throughput provide ample headroom for many compact control tasks. Implementation should include worst-case interrupt-latency analysis, watchdog and reset planning, and a check that every external signal meets the electrical limits defined in the Texas Instruments datasheet.
Recommandé
Audio Signal Processing
The TMS320F241FNA can perform deterministic fixed-point audio tasks such as equalization, mixing, filtering, and dynamic processing in embedded signal-processing equipment. Its 16-bit datapath aligns with common fixed-point audio formats, while the 20 MHz C24x core provides up to 20 MIPS for control and transform routines. The 16 KB flash is suitable for compact programs when memory budgeting is handled carefully. Audio designs should verify supported peripherals, timing, and external interface requirements in the manufacturer datasheet; the DSP does not itself remove the need for suitable converters and output amplification.

Notes de conception
Design the PCB footprint for the exact 68-pin J-bend PLCC package and verify lead pitch, body dimensions, and terminal orientation against the Texas Instruments package drawing. The listed 24.23 mm by 24.23 mm body requires more board area than a leadless package. Provide appropriate solder-joint and copper-clearance geometry, and avoid placing tall or mechanically sensitive components where they can interfere with assembly.
Do not substitute a processor solely because it belongs to the C2000 family. A true drop-in decision requires the same 68-pin PLCC footprint, matching pin functions, compatible electrical conditions, and software support for the C24x instruction set and peripherals. Check every signal against the TMS320F241 datasheet, including power, ground, reset, interrupt, memory, and peripheral pins. Unused pins must follow the manufacturer's termination guidance.
Separate analog and digital return paths carefully and connect all ground pins according to the package and layout guidance in the manufacturer datasheet. The processor operates from a 5 V supply, so supply decoupling, voltage sequencing, and startup behavior must be designed with the power architecture of the target system. Confirm bypass values and permissible capacitor characteristics from the datasheet rather than applying a generic decoupling rule.
Treat clock, reset, interrupt, and external peripheral lines as critical digital signals even though the architecture uses a modified Harvard organization for internal program and data access. Route clocks away from high-speed switching nodes, provide a defined return path, and keep external interfaces away from potential sources of coupling. Validate the final layout for settling time and margin using the processor's published timing requirements.
Informations de conformité
The industrial temperature grade is identified for TMS320F241FNA, but RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status require confirmation from the manufacturer.
