Details: 
If the USB interface (device mode) is used for an application completely powered with 1.8V, is it possible to power Kinetis-K MK20DX128VFM5 MCU with the 1.8V and the USB be powered by the USB port so that the signaling levels work out?

Answers

A: 
Yes, the Kinetis MK20DX128VFM5 MCU can be powered with 1.8v and use the USB VBUS signal (5V on the USB connector) to supply the Internal USB regulator and get 3.3V to supply the USB transceiver ensuring that the 48MHz clock is available on the USB transceiver.

A: 
Yes, Speex SW codec is required. Speex is an open source patent-free audio codec specially developed for speech encoding and decoding with a high compression ratio and a sufficient sound quality. For higher recording performances, it is recommanded to use an external codec like Freescale SGTL5000.

What is the advantage of the Touch Sensor Interface (TSI) module available like in Kinetis-K series MK20DX128VFM5 MCU over a software solution?

Answers

A: 
TSI is an electrode capacitive scan method based on hardware supported by the Freescale TSS library, which makes the configuration and use of the module much easier.
Compared to a software scan method, TSI module offers to your touch application more robustness against electrical noise, more sensitivity, the ability to work in, and wake up from, low power modes, no need for external hardware (except electrode), more configuration possibilities and interrupts for simplified real-time processing.

Answers

A: 
Yes, The Kinetis MK20DX128VFM5 MCU (part-numbers with a X before memory size) include a FlexMemory feature. The FlexMemory allows to configure some of the on-chip flash memory as enhanced EEPROM, additional flash memory, or a combination of the two. The enhanced EEPROM (EEE) capability of the FlexMemory has a number of features that allow the replacement of external EEPROMs and improves upon their performance: Configurability (distribution of the amount of EEE and flash memory required), High endurance EEE memory (over 100 M cycles depending on configuration), Supports byte, word, and longword accesses, Fast write times (~100 us for a write to a pre-erased location, and 1.5 ms for an erase and program), EEE functionality across the full operating voltage range for the processor (1.71 V – 3.6 V).
