LM3S818 Datasheet, PDF (31/572 Pages) Bookham, Inc. – Microcontroller

Stellaris^® LM3S818 Microcontroller
– 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
■ UART
– Two fully programmable 16C550-type UARTs
– 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
– Standard asynchronous communication bits for start, stop, and parity
– Line-break generation and detection
– Fully programmable serial interface characteristics
• 5, 6, 7, or 8 data bits
• Even, odd, stick, or no-parity bit generation/detection
• 1 or 2 stop bit generation
■ Synchronous Serial Interface (SSI)
– Master or slave operation
– Programmable clock bit rate and prescale
– Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
