MKL27Z64VFM4

The Kinetis KL27 microcontroller supports one UART module with the following features: - Full-duplex operation - 13-bit baud rate selection with /32 fractional divide, based on the module clock frequency - Programmable 8-bit or 9-bit data format - Programmable transmitter output polarity - Programmable receive input polarity - Up to 14-bit break character transmission - 11-bit break character detection option - Two receiver wakeup methods with idle line or address mark wakeup - Address match feature in the receiver to reduce address mark wakeup ISR overhead - Ability to select MSB or LSB to be first bit on wire - Support for ISO 7816 protocol to interface with SIM cards and smart cards - Receiver framing error detection - Hardware parity generation and checking The Kinetis KL27 microcontroller supports one UART module with a maximum operating speed of 48 MHz.

The Kinetis KL27 Microcontroller offers several key features related to low-power operation, including: - USB FS 2.0 device without requiring an external crystal - High accuracy internal voltage and clock reference - Down to 46 µA/MHz in very low power run mode and 1.68 µA in stop mode (RAM + RTC retained) - Low-leakage wakeup unit - Two-pin SWD (serial wire debug) programming and debug interface These features make the Kinetis KL27 Microcontroller optimized for cost-sensitive and battery-powered applications requiring low-power USB connectivity.

The ARM Cortex-M0+ core in the Kinetis KL27 microcontroller can operate up to 48 MHz.
