Development Board, Kinetis M Series Tower System Module

The TWR-KM34Z50M and TWRKM34Z50MV3 microcontroller modules are designed to work either in standalone mode or as part of the Freescale Tower System, a modular development platform that enables rapid prototyping and tool reuse through reconfigurable hardware. • Tower-compatible microcontroller module • MKM34Z128CLL5 (for TWR-KM34Z50M) or MKM34Z128ACLL5 (for TWRKM34Z50MV3) MCU (50 MHz, 128 KB Flash, 16 KB RAM, low power, LQFP100 package) • USB interface with Mini-AB USB connector • Large 160-segment glass LCD • Onboard debug circuit: open source JTAG/SWD (OpenSDA) with virtual serial port • Three-axis accelerometer/anti-tamper tilt sensor (MMA8491Q) • Four user-controllable LEDs • Two user pushbutton switches for GPIO interrupts • One user pushbutton switch for tamper detection • One user pushbutton switch for MCU reset • Potentiometer • Headers for direct GPIO and ADC access • External Tamper pins • Independent, battery-operated power supply for real-time clock (RTC) and tamper detection modules • Onboard 7-channel sinusoidal signal generator with USB interface for emulating the AC net waveforms • IRDA support • NTC temperature sensor • General-purpose Tower Plug-in (TWRPI) socket
