XF28E120SCTVFC-Texas Instruments-Price, Stock & Datasheet

The F28E12x is a member of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices designed for efficiency in motor drive applications.

The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 160MHz of signal-processing performance for fixed-point code running from either on-chip flash or SRAM.

The F28E12x supports up to 128KB (64KW) of flash memory. Up to 16KB (8KW) of on-chip SRAM is also available to supplement the flash memory.

High-performance analog blocks are integrated into the F28E12x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide optimal real-time signal chain performance. Eight PWM channels enable control of various power stages from a 3-phase inverter to power-factor correction and other advanced multilevel power topologies.

Interfacing is supported through various industry-standard communication ports (such as SPI, SCI, I2C, and UART) and offers multiple pin-muxing options for optimal signal placement.
