† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied.

Description

The TMS320C240 and TMS320F240 devices are the first members of a new family of DSP controllers based on the TMS320C2xx generation of 16-bit fixed-point digital signal processors (DSPs). Unless otherwise noted, the term 'x240 refers to both the TMS320C240 and the TMS320F240. Table 1 provides a comparison of the features of each device. The only difference between these two devices is the type of program memory: the 'C240 contains 16K words of ROM and the 'F240 contains 16K words of flash. This new 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 s. See the functional block diagram.
