TI TMS320F28069PZT

The F2806x Piccolo series microcontrollers (MCUs) power the C28x core and the CLA coupled with highly integrated control peripherals in devices with fewer pins. The code of the devices in this series is compatible with the legacy C28x-based code and features high analog integration. An internal voltage regulator enables single power rail operation. The high-resolution pulse width modulator (HRPWM) module has been enhanced to support dual-edge control (frequency modulation). An analog comparator with a 10-bit internal reference has been added to the device, which can directly control the ePWM output. The ADC can perform conversions within a fixed full-scale range of 0V to 3.3V and supports ratio-metric operation with VREFHI/VREFLO references. The ADC interface has been optimized for low overhead and latency.
