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 µs.
