●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.
