TMS320F240PQS - 20MHz 16-Bit Flash DSP | Texas Instruments
料号： TMS320F240PQS ✓ 量产中TMS320F240PQS 概述
A digital signal processor is a specialized microprocessor architecture designed to execute mathematical and control algorithms efficiently. A DSP controller extends that processing capability with embedded memory, digital I/O, timers, analog interfaces, and control-oriented peripherals. The TMS320F240PQS sits in the hierarchy of digital signal controller, fixed-point DSP, microcontroller, embedded processor, and semiconductor. It is intended for systems requiring deterministic real-time control rather than general-purpose computing.
The most prominent verified specifications are the 20 MHz operating frequency, 16-bit processor architecture, 32 KB of flash memory, 132-pin BQFP package, and 5 V operating supply identified in the component-comparison data. Its flash memory allows control firmware to be stored directly on the controller. The large 132-pin package exposes the device's extensive motor-control peripheral set, while its 20 MHz clock supports processing associated with the verified 20 MIPS performance figure.
The TMS320F240 architecture uses the C2xLP core CPU for fixed-point signal and control processing. Its combination of flash program memory and dedicated real-time peripherals distinguishes it from earlier RAM-programmed DSP controllers. This makes the part relevant to closed-loop motor systems, where acquisition, filtering, transformation, modulation, and actuator calculations must occur within a predictable control interval. The verified family description specifically identifies digital motor and motion control as the optimization target.
Typical uses include digital motor control, industrial automation, power-converter control, servo systems, and embedded signal-processing equipment. In such systems, the controller can execute control algorithms while its communication and timing peripherals coordinate external sensors, power stages, and protection functions. The 132-pin BQFP package is appropriate for through-hole industrial or legacy control boards where a large pin count simplifies access to numerous control and communications signals.
Designers should verify the complete pinout, timing, peripheral configuration, and electrical limits against the manufacturer datasheet before laying out a new PCB. The verified data does not expose a complete machine-readable 132-pin assignment, so no pin names are inferred here. The 132-pin BQFP package also requires careful lead clearance, solder-joint inspection, and consideration of thermal performance when the controller is mounted alongside power-conversion circuitry.
This product record combines verified distributor specifications, source links, package information, lifecycle context, and application-oriented engineering guidance. It distinguishes documented facts from missing data and avoids presenting unverified pin assignments, prices, compliance declarations, or substitute parts as established facts.

典型应用
TMS320F240PQS 适用于 6 应用s: Digital Motor Control, Motion-Control Systems, Industrial Power-Converter Control, Servo-Drive Control, Embedded Signal Processing, Legacy Industrial Control Boards.
Digital Motor Control
The TMS320F240PQS fits digital motor control because it is a 16-bit fixed-point DSP controller operating up to 20 MHz with 20 MIPS performance and 32 KB of flash memory. It can execute feedback, filtering, and modulation algorithms while coordinated timing peripherals manage the control sequence. The verified family description explicitly identifies digital motor control as an optimization target. Its 132-pin BQFP provides access to the controller's extensive control-oriented signals, although every pin assignment must be checked against the manufacturer datasheet before routing. Using the embedded flash for resident control code also avoids an external program-memory interface in a dedicated controller design.
推荐
Motion-Control Systems
The TMS320F240PQS is appropriate for motion-control systems that require deterministic fixed-point computation at up to 20 MHz. Its 20 MIPS processing capability supports real-time control calculations, while 16 KB x 16 words of flash hold application firmware and 1.0625 KB of data RAM supports working state. The verified Texas Instruments family information positions the controller for motion-control applications rather than general-purpose processing. The 132-pin package can expose the numerous digital control, communication, and peripheral signals needed by a legacy through-hole motion-control board, subject to full pin-level verification.
推荐
Industrial Power-Converter Control
The TMS320F240PQS can serve as the control processor in an industrial power-converter control board when the design requires deterministic 16-bit fixed-point math. Its 20 MHz clock and 20 MIPS rate provide computational margin for sampling, loop-control, and supervisory functions, while the 5 V supply matches the verified device operating class. The 132-pin BQFP can support access to timing, pulse, capture, and communications resources. Engineers must confirm analog-interface requirements and peripheral multiplexing in the datasheet because the supplied snippets do not enumerate those functions or pins.
推荐
Servo-Drive Control
The TMS320F240PQS is suitable for servo-drive control because its 16-bit fixed-point architecture can process position, velocity, and current-loop calculations at a 20 MHz clock. The 32 KB flash area is large enough to hold dedicated real-time control firmware, and the 132-pin package exposes the peripheral connections commonly needed in a multi-axis controller. Its specified -40 °C to +125 °C operating range is appropriate for industrial environments. Final signal selection, timing, and isolation requirements must be validated against the complete manufacturer datasheet rather than inferred from the distributor summary.
推荐
Embedded Signal Processing
The TMS320F240PQS can implement embedded fixed-point signal-processing tasks alongside real-time control. Its 20 MIPS throughput, 16-bit data path, and C2xLP core architecture are suited to filtering, transformations, and related algorithms, while 32 KB of on-chip flash supports resident firmware. Using a DSP controller rather than a general-purpose microcontroller can simplify deterministic execution when sampling and computation must share a hardware platform. The supplied data does not enumerate algorithm accelerators or peripheral mappings, so developers should verify whether the required filters, communications channels, and external interfaces are present in the selected device variant.
推荐
Legacy Industrial Control Boards
The TMS320F240PQS is relevant to legacy industrial control boards designed around the 132-pin BQFP footprint. Its 16-bit fixed-point processing, 20 MHz operating frequency, and embedded flash combine computational capability with a compact controller implementation, while the large leaded package remains practical for through-hole boards assembled in industrial volumes. The package dimensions are verified at 24.13 mm by 24.13 mm, allowing mechanical checks against existing enclosures. Because the supplied data does not provide a complete pinout, board reuse must begin with a pin-by-pin comparison and must not rely only on the matching package designation.

- Full commercial ordering-code retention （对比 TMS320F240PQG4)
设计说明
Do not approve a replacement solely because it is listed in a 132-pin BQFP package. Confirm every power, ground, peripheral, interrupt, and communication signal against the manufacturer datasheet, then verify the ordering suffix, temperature grade, qualification status, and device marking. The verified evidence directly establishes TMS320F240PQ and TMS320F240PQG4 as same-family candidates, but it does not supply a complete pin-assignment table for an unconditional production substitution.
The TMS320F240PQS uses a 132-pin BQFP package measuring 24.13 mm by 24.13 mm. Preserve the manufacturer's land pattern, pin-1 orientation, courtyard, and solder-mask geometry exactly; a mechanically similar package does not guarantee electrical compatibility. For leaded through-hole designs, verify drill tolerances, pad diameters, annular rings, and the available component-body clearance against the enclosure and adjacent heat sinks before releasing the layout.
The supplied data verifies a -40 °C to +125 °C operating-temperature range but does not provide power dissipation, junction-temperature limits, or thermal resistance. Therefore, no numerical thermal estimate is presented. In a power-converter or motor-control system, calculate dissipation from the actual 5 V supply current and use the manufacturer thermal information and the board's copper area for a junction-temperature check. Isolate the controller thermally from nearby power stages where practical.
Treat clock, reset, interrupt, and high-speed control signals as timing-critical routes after their assignments are confirmed in the datasheet. Keep the 20 MHz clock path short, provide a clean return path, and place required bypassing capacitors close to the relevant supply pins using the manufacturer's recommended values and layout. Avoid deriving layout assumptions from peripheral names or examples alone because the verified snippets do not enumerate the complete TMS320F240PQS pinout.
合规信息
The supplied verified data does not extract explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for TMS320F240PQS. TMS320F240PQG4 appears in comparison results, but the supplied snippet does not define the G4 designation, so it was not used to infer compliance.
