Submitted by: sardtra najakhun (

Features 32-bit ARM® Cortex™-M3 50-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), and Thumb-2 instruction set Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller 64 KB single-cycle flash and 8 KB single-cycle SRAM 0-30 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration ARM FiRM-compliant Watchdog Timer ; plus three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers/counters and can be configured to operate independently 10-bit Analog-to-Digital Converter (ADC) with six analog input channels and a sample rate of one million samples/second Two fully programmable 16C550-type UARTs Synchronous Serial Interface (SSI), supporting operation for Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces One integrated analog comparator configurable for output to initiate an ADC sample sequence, drive an output pin or generate an interrupt Three PWM generator blocks, each with one 16-bit counter, two PWM comparators, a PWM signal generator, a dead-band generator, and an interrupt/ADC-trigger selector Quadrature Encoder Interface (QEI) featuring position integrator to track encoder position and velocity capture using built-in timer Industrial and extended temperature RoHS-compliant 48-pin LQFP and 48-pin QFN package
