TMS320F240PQA - 20MHz 16-Bit Flash DSP | TI
MPN: TMS320F240PQA ✓ ActiveTMS320F240PQA Overview
A digital signal processor is a specialized microprocessor architecture optimized for arithmetic-intensive operations on sampled signals. Within the semiconductor hierarchy, the TMS320F240 belongs to the 16-bit fixed-point DSP controller family, combines a DSP core with embedded control peripherals, and provides deterministic execution for motor-control, power-conversion, and industrial signal-processing systems. Its C2xx-class architecture is object compatible with the TMS320C2xx family and source-code compatible with the TMS320C25 family.
The device includes 32 KB of on-chip flash memory, allowing control code and constant data to be stored locally without an external program-memory device. The 16-bit data architecture supports efficient fixed-point arithmetic, while the 20 MHz operating frequency provides a 50 ns instruction-cycle reference. The 132-pin plastic quad flat package exposes the processor, memory, control, communications, and power-management resources required by a standalone DSP controller.
The TMS320F240 architecture is designed around a high-performance static CMOS implementation. Its fixed-point processing core is intended for deterministic control loops and real-time signal transformation, where predictable arithmetic throughput and direct hardware control are more important than general-purpose operating-system support. The flash-enabled F240 variant simplifies standalone system development compared with ROM-based C2xx controllers that require external program storage.
Typical applications include digital motor control, inverter and power-converter control, industrial automation, communications signal processing, and embedded control systems with deterministic timing requirements. The combination of a 20 MHz DSP core, 32 KB of flash memory, and a broad set of embedded control peripherals allows the processor to combine control-law execution and signal conditioning in a single device.
Designers should preserve the pin assignment, power-supply requirements, and external clock arrangement specified by the manufacturer datasheet. Because this is a 132-pin legacy quad flat package, PCB layout must account for its large body size and fine-pitch lead geometry. Firmware should also be validated for timing, peripheral sharing, and interrupt behavior before production deployment.
This product page consolidates the verified device identity, memory organization, package data, operating limits, sourcing guidance, pin-compatible family information, and practical design considerations needed to evaluate the TMS320F240PQA before starting an embedded DSP design.

Typical Applications
TMS320F240PQA is suitable for 6 applications: Digital Motor Control, Inverter and Power-Converter Control, Industrial Automation, Communications Signal Processing, Digital Audio Processing, Embedded Control with Local Flash.
Digital Motor Control
The TMS320F240PQA fits digital motor-control systems that require deterministic fixed-point computation, local flash storage, and direct access to embedded control peripherals. Its 16-bit C2xx-class core runs at up to 20 MHz, giving each instruction cycle a 50 ns reference, while 32 KB of on-chip flash holds control code and tuning constants without an external program-memory device. The 5 V device and 132-pin BQFP package fit industrial control-board layouts designed around the TMS320F240 family. Designers should confirm PWM channels, capture/compare resources, analog interfaces, timer relationships, and board-level signal conditioning against the manufacturer datasheet.
Recommended
Inverter and Power-Converter Control
The TMS320F240PQA is appropriate for inverter and power-converter controllers that execute deterministic current and voltage control loops. Its 16-bit fixed-point architecture avoids the overhead of a general-purpose control platform, while the 20 MHz operating rate supports frequent control-loop updates and peripheral servicing. The 32 KB flash memory can retain control algorithms, modulation tables, calibration values, and fault-handling routines. Because the processor operates from 5 V, the power stage still requires suitable gate drivers, current and voltage sensing, protection circuitry, and isolation or level-shifting where the external interface demands it.
Recommended
Industrial Automation
The TMS320F240PQA supports industrial automation designs that combine real-time signal processing with embedded machine control. Its 50 ns instruction-cycle reference and dedicated DSP architecture enable predictable execution of acquisition, filtering, and actuator-control routines, while on-chip flash supports autonomous operation after power-up. The industrial −40 °C to +85 °C range makes the device suitable for many factory environments when enclosure temperature and thermal rise remain within the specified limits. The 132-pin BQFP footprint requires a carefully routed multilayer PCB, and production firmware should validate watchdog behavior, peripheral arbitration, communications timing, and fault recovery.
Recommended
Communications Signal Processing
The TMS320F240PQA can serve embedded communications equipment that performs fixed-point filtering, modulation, demodulation, or signal-quality processing. Its 16-bit data path and 20 MHz execution rate are suited to deterministic real-time workloads, while 32 KB of flash provides space for a self-contained control and signal-processing application. Peripheral selection and external interface design remain central to the implementation: communications designs must confirm available timers, serial ports, parallel interfaces, memory timing, and interrupt priorities in the manufacturer datasheet. A separate network or transceiver device may be required because the TMS320F240 is a DSP controller rather than a dedicated network controller.
Recommended
Digital Audio Processing
The TMS320F240PQA can implement deterministic digital audio functions when a design requires a standalone fixed-point processor rather than a general-purpose audio interface. Its 20 MHz C2xx-class core supports real-time mixing, filtering, or control computations, and its 32 KB flash capacity accommodates application firmware and fixed data tables. Audio performance remains dependent on the selected sample rate, filter structure, memory interface, and external converters, so those parameters must be evaluated as a complete signal chain. The 5 V supply and 132-pin package make board planning important, particularly around converter grounding, clock jitter, and separation between analog and digital return currents.
Recommended
Embedded Control with Local Flash
The TMS320F240PQA is useful in standalone embedded controllers where local nonvolatile program storage simplifies deployment. Its 32 KB flash memory holds control firmware without requiring a separate external ROM, while 1.0625 KB of data RAM provides working space for variables and buffers. The 20 MHz fixed-point core can execute acquisition and control routines concurrently with communication tasks, subject to the interrupt and peripheral timing defined in the datasheet. Because this device belongs to a legacy embedded-DSP architecture, developers should establish toolchain, debugger, library, and long-term software-support requirements before committing the design to a new platform.

Design Notes
Route the 132-pin BQFP footprint exactly according to the manufacturer package drawing, including pin-1 orientation and exposed pad or thermal requirements where applicable. Place input and output decoupling capacitors close to their corresponding pins, keep the 5 V supply path compact, and provide a low-impedance ground plane. Confirm land-pattern dimensions against the current package drawing before releasing artwork; the 24.13 × 24.13 mm body size should not be treated as the solder-land pattern itself.
Separate clock, analog, and digital return paths carefully because the TMS320F240PQA combines a 20 MHz digital core with external analog and power-control functions. Use short clock traces, avoid routing switching-node or high-current power paths beneath the processor, and follow the datasheet grounding recommendations. If the design senses analog voltages, establish grounding and filtering methods before relying on control-loop accuracy; digital timing performance alone does not validate measurement quality.
Do not select a related C2000 model solely because its processor type or family name is similar. Before replacing the TMS320F240PQA, verify all 132 pin assignments, 5 V electrical requirements, 20 MHz clock assumptions, 32 KB flash organization, peripheral mapping, interrupt behavior, and software toolchain compatibility. A true drop-in replacement must preserve the board footprint and critical device functions; the TMS320F240PQS is the specifically documented pin-compatible alternative for temperature-grade changes.
Compliance Information
No specific RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements were established for the exact TMS320F240PQA ordering code. The listed −40 °C to +85 °C range is an industrial temperature specification and does not by itself establish AEC-Q100 qualification.
