description
The TMS320F243 and TMS320F241 devices are members of the ’24x family of digital signal processor (DSP)
controllers based on the TMS320C2xx generation of 16-bit fixed-point DSPs. The ’F243 is a superset of the
’F241. These two devices share similar core and peripherals with some exceptions. For example, the ’F241
does not have an external memory interface. This new family is optimized for digital motor / motion control
applications. The DSP controllers combine the enhanced TMS320 architectural design of the ’C2xx 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 PWM registers to generate PWM outputs, and a single,10-bit analog-to-digital
converter (ADC), which can perform conversion within 1 µs.
