description
The TMS320F240 (F240) device is a member of a family of DSP controllers based on the TMS320C2xx
generation of 16-bit fixed-point digital signal processors (DSPs). This family is optimized for digital motor/motion
control applications. The DSP controllers combine the enhanced TMS320 architectural design of the C2xLP
core CPU for low-cost, high-performance processing capabilities and several advanced peripherals optimized
for motor/motion control applications. These peripherals include the event manager module, which provides
general-purpose timers and compare registers to generate up to 12 PWM outputs, and a dual10-bit
analog-to-digital converter (ADC), which can perform two simultaneous conversions within 6.1 µs. See the
functional block diagram.
