The TMS320F240PQS is a 16-bit fixed-point DSP with a C2xx core at 20 MHz. It has 32 KB Flash, 1K x 8 RAM, a 16-channel 10-bit ADC, PWM, WDT, and POR in a 132-BQFP package.
Lifecycle reality — obsolete, no direct replacement
The TMS320F240PQS is marked obsolete by Texas Instruments. There is no official pin-compatible successor; later C24x and Delfino parts use different package footprints and supply voltages.
Peripheral set — what is on-chip
The ADC samples 16 single-ended channels at 10-bit resolution, enough to capture three-phase currents plus DC-link voltage and a resolver or encoder position. The PWM module generates complementary center-aligned waveforms with dead-band insertion. SCI and SPI ports handle serial communication; the external bus interface (EBI/EMI) can expand memory or connect to an external FPGA.
