The SMJ320F240 is a member of a family of digital signal processor (DSP) controllers based on the TMS320C2xx generation of 16-bit fixed-point DSPs. This family is optimized for digital motor/motion control applications and contains 16K words of flash memory on chip. The DSP controller combines 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 dual 10-bit analog-to-digital converter (ADC), which can perform two simultaneous conversions within 6.1 µs.
The functional block diagram provides a high-level description of each component in the F240 DSP controller. The SMJ320F240 device is composed of three main functional units: a C2xx DSP core, internal memory, and peripherals. In addition to these three functional units, there are several system-level features of the F240 that are distributed. These system features include the memory map, device reset, interrupts, digital input/output (I /O), clock generation, and low-power operation.
