TMS320F240PQ - 16-Bit 20MHz DSP | Texas Instruments
Référence : TMS320F240PQ ✓ ActifTMS320F240PQ Présentation
A digital signal processor controller is a microprocessor optimized for arithmetic-intensive real-time operations. Unlike a general-purpose microcontroller, this device is organized for efficient fixed-point signal processing, control-loop execution, and high-speed peripheral data transfer. In the device hierarchy, the TMS320F240PQ belongs to the digital signal processor controller class, combining a DSP core with flash memory and control-oriented peripherals.
Key features include a 16-bit architecture, 20 MHz clocking, 32 KB of flash organized as 16K x 16 words, and 1,088 bytes of RAM. The verified part description identifies SPI, UART, USART, SCI, and EBI/EMI interfaces. The 50 ns instruction-cycle figure and dedicated serial interfaces support deterministic control and communication tasks, while the embedded flash allows standalone firmware storage without an external program-memory device.
The TMS320F240PQ operates from a 5 V supply and is specified over 0°C to 70°C. Its 132-pin BQFP package provides the signal and peripheral connections required by this mixed-signal controller family. Unlike a bare DSP, the integrated flash and communication peripherals reduce the number of external components required in a self-contained industrial controller.
Typical applications include digital motor control, industrial automation, power-converter control, communications equipment, embedded signal processing, and factory automation. Its fixed-point DSP core is suitable for filtering, feedback control, waveform generation, and real-time sampling where fixed execution timing and deterministic peripheral interaction are important.
Designers should preserve the 5 V supply limits, provide appropriate decoupling, and verify every signal against the 132-pin package drawing. The 0°C to 70°C rating is suitable for commercial-temperature equipment but not extended industrial temperature ranges. PCB layout, exposed pad, and thermal requirements beyond the verified information require review of the manufacturer datasheet.
This page consolidates verified distributor specifications, package information, sourcing details, and constrained drop-in alternatives. It also separates confirmed engineering facts from unavailable parameters, helping engineers evaluate this legacy DSP controller before committing to a 132-BQFP PCB design or migration.

Applications typiques
TMS320F240PQ convient pour 6 applications: Digital Motor Control, Industrial Automation and Factory Control, Power Converter Control, Communications Signal Processing, Industrial Data Acquisition, Embedded Control with Flash Storage.
Digital Motor Control
The TMS320F240PQ fits digital motor-control loops that require deterministic fixed-point arithmetic, a 20 MHz instruction clock, and embedded program storage. Its 16-bit architecture and 50 ns instruction-cycle rating support rapid feedback calculations, while the 1,088-byte RAM provides working space for control variables and the 32 KB flash stores control algorithms. The SPI, UART, USART, SCI, and EBI/EMI interfaces allow the controller to exchange commands and data with sensors, gate drivers, and supervisory electronics. Because the device is specified from 0°C to 70°C, it is best suited to commercial-temperature enclosures unless a separate qualification review establishes otherwise.
Recommandé
Industrial Automation and Factory Control
The TMS320F240PQ is suitable for factory automation modules that combine real-time signal processing with embedded control firmware. Its 32 KB of flash supports standalone program storage, and the 5 V supply, EBI/EMI interface, and multiple serial peripherals reduce the need for separate interface devices. A 20 MHz clock gives designers a 50 ns instruction-cycle basis for organizing acquisition, filtering, and control tasks. The commercial 0°C to 70°C rating should be checked against the installed enclosure temperature, while the 132-BQFP footprint requires adequate PCB routing space and careful escape routing for its high pin count.
Recommandé
Power Converter Control
The TMS320F240PQ can serve as the computation engine in digital power-converter control where fixed-point feedback algorithms must execute at a predictable rate. Its 20 MHz clock and 16-bit DSP architecture suit sampled current and voltage regulation, compensation, and fault sequencing, while embedded flash permits self-contained firmware. The EBI/EMI interface provides access to external memory or peripheral devices when working storage is insufficient. Designers must account for the 5 V operating supply, separate analog and digital grounding strategies, and control-loop timing when pairing the processor with power-stage isolation and gate-drive circuitry.
Recommandé
Communications Signal Processing
The TMS320F240PQ is appropriate for communication equipment that performs real-time filtering, modulation-related arithmetic, or protocol handling alongside embedded control. Its 16-bit fixed-point DSP core processes sampled data at a 20 MHz clock rate, and its 1,088 bytes of RAM can support short working buffers. UART, USART, SCI, and SPI interfaces provide multiple paths for connecting transceivers, sensors, and host processors. Designers should validate buffer latency, interrupt timing, and signal integrity against the application, because the verified data does not specify detailed peripheral timing or memory-map behavior.
Recommandé
Industrial Data Acquisition
The TMS320F240PQ supports compact data-acquisition modules where sampled signals must be filtered or conditioned in real time without a separate high-performance processor. Its 20 MHz clock provides a 50 ns instruction-cycle basis, and the 32 KB flash stores acquisition code and lookup data. The EBI/EMI interface can connect external memory or bus-oriented peripherals, while SPI and UART provide sensor and host connectivity. Practical designs should include input protection, reference conditioning, and decoupling outside the IC. The 132-BQFP package and 24.13 mm by 24.13 mm body also demand a dense but methodical board layout.
Recommandé
Embedded Control with Flash Storage
The TMS320F240PQ is useful in standalone embedded controllers that require code and constant data to remain resident without an external program-memory device. Its 32 KB flash provides 16K x 16 words of storage, and the 20 MHz DSP core handles arithmetic-heavy supervisory and control functions. Serial peripherals allow programming and diagnostics through UART, USART, SCI, or SPI, while the EBI/EMI interface expands access to external resources. For deployment, verify that the application fits both flash and RAM, account for the 5 V supply, and maintain the specified 0°C to 70°C commercial-temperature range.

Notes de conception
Design the supply around the verified 5 V operating requirement and validate the permitted tolerance from the manufacturer datasheet before selecting the regulator. Place local high-frequency decoupling at the power pins and route return currents through a low-impedance plane rather than through signal traces. Because the supplied excerpts do not provide a complete power-pin list, current requirements, or absolute-maximum voltage limits, do not derive a final component size from this page alone.
Treat the 132-BQFP footprint as a high-pin-count escape-routing problem and use the manufacturer land pattern as the controlling PCB geometry. Keep the processor's external-bus and serial-interface traces away from sensitive analog inputs, use short return paths, and maintain continuous ground-plane continuity beneath the device where the package construction permits. The verified material does not include a pin table or exposed-pad drawing, so the PCB library must not be released until those details have been checked against the official package drawing.
Estimate controller dissipation from the actual 5 V rail, internal core voltage, and measured activity rather than assuming that a 20 MHz clock alone determines power. Compare the resulting junction-temperature estimate with the package construction and the specified 0°C to 70°C ambient range. The verified sources do not provide thermal resistance or maximum junction temperature, so no defensible heatsink calculation can be made until those manufacturer ratings are available.
Do not assume that every 132-pin C2000-family ordering code is interchangeable. The verified replacements have the same package, but suffix-specific temperature, qualification, marking, or sourcing differences may still affect production acceptance. Preserve the original software target, memory map, peripheral configuration, and package drawing, and obtain written Texas Instruments confirmation before approving a substitute. This prevents an apparently compatible package from introducing an unverified procurement or qualification mismatch.
Informations de conformité
The verified excerpts identify the device as a Texas Instruments C2xx DSP controller but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance status has been inferred.
