The TMS320F240PQ: It packs 32 KB of on-chip Flash program memory and 1K x 8 of RAM, plus a 16-channel 10-bit ADC, PWM generation, and serial interfaces (SCI, SPI, UART). This part was designed for real-time control applications such as motor drives, uninterruptible power supplies, and industrial inverters where deterministic loop timing matters more than raw MIPS. The 20 MHz clock, combined with the DSP's single-cycle MAC, gives it enough headroom for a typical 10–20 kHz current-control loop with sensor feedback.
Obsolete – planning the BOM transition
The TMS320F240PQ is obsolete per Texas Instruments' product lifecycle status. No further production runs are planned, and available stock is through independent distribution or surplus channels.
Peripheral set and memory budget
The on-chip peripherals include a PWM module with programmable deadband, a watchdog timer, and a power-on-reset circuit – essentials for open-loop and closed-loop motor control without external glue logic. The 16-channel 10-bit ADC samples at a rate sufficient for three-phase current sensing plus auxiliary inputs, though the 10-bit resolution limits precision for high-accuracy servo loops. The 32 KB Flash and 1K x 8 RAM are tight by modern standards; firmware must be carefully sized, and any lookup tables or data buffers will eat into the RAM quickly. The 28 general-purpose I/O pins handle switch inputs, relay drivers, and status LEDs.
