Texas Instruments (TI) states that their new C2000 Piccolo F2807x MCUs doubles system performance without doubling your cost or changing your hardware or software design. With the combination of the C28x CPU and accelerators, the new MCUs boost execution speeds of control tasks in industrial applications such as telecom rectifiers, server power, solar micro inverters, frequency inverters and automotive HEV/EV. The F2807x MCUs also provide many analog and control peripherals to enable more integrated control applications. They are scalable with the previously announced C2000 Delfino F2837xS and F2837xD MCU generations.
Designers looking to tap into the performance of the C2000 Piccolo F2807x MCUs can leverage the real-time control accelerator (CLA). The CLA doubles the throughput of the F2807x MCU, providing an additional 120 MHz of floating-point processing capability. This additional bandwidth allows designers to run parallel math-intensive or time-sensitive signal processing tasks. Offloading these tasks to the CLA enables the CPU to focus on general system tasks such as diagnostics, communications, motion profiling and more. Also integrated in the main C28x CPU is a trigonometric math unit (TMU) accelerator, which enables the chip to quickly execute trigonometric-based algorithms used in transforms and control functions.
The new MCUs are also packed with high-end, smart analog and control integration — including a flexible, enhanced pulse-width modulator (PWM) that supports all digital power topologies — to decrease digital control system complexity. Three 12-bit ADCs increase sampling throughput by allowing designers to do simultaneous tasks such as monitor voltages and currents of three-phase motors while simultaneously decoding high-frequency resolver feedback. Additionally, the F2807x MCUs can simultaneously process eight delta-sigma modulated channels, each with threshold comparators and a seamless interface to the TI AMC1204 isolated delta-sigma modulator, for isolated current and voltage measurements. Window comparators provide critical power stage protection.
Fully featured C2000 Piccolo F2807x 32-bit MCUs (TMX320F28075) are now sampling. Production versions of the F28075 and F28074 (TMS320F28074) will start at less than $9 USD in 1K unit orders. Developers can evaluate their new Piccolo F2807x MCUs using the Experimenter’s Kit docking station (TMDXDOCK28075) for $189 and include the modular controlCARD (TMDXCNCD28075) for $129.
