LM3S2616 Datasheet, PDF (38/753 Pages) Texas Instruments – Stellaris® LM3S2616 Microcontroller

Architectural Overview
– 32-bit down counter with a programmable load register
– Separate watchdog clock with an enable
– Programmable interrupt generation logic with interrupt masking
– Lock register protection from runaway software
– Reset generation logic with an enable/disable
– User-enabled stalling when the controller asserts the CPU Halt flag during debug
■ ADC
– Six analog input channels
– Single-ended and differential-input configurations
– On-chip internal temperature sensor
– Sample rate of one million samples/second
– Flexible, configurable analog-to-digital conversion
– Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
– Flexible trigger control
• Controller (software)
• Timers
• Analog Comparators
• PWM
• GPIO
– Hardware averaging of up to 64 samples for improved accuracy
– Converter uses an internal 3-V reference
– Power and ground for the analog circuitry is separate from the digital power and ground
■ UART
– Fully programmable 16C550-type UART with IrDA support
– Separate 16x8 transmit (TX) and receive (RX) FIFOs to reduce CPU interrupt service loading
– Programmable baud-rate generator allowing speeds up to 3.125 Mbps
– Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
– FIFO trigger levels of 1/8, 1/4, 1/2, 3/4, and 7/8
