LM3S6950 Datasheet, PDF (24/524 Pages) List of Unclassifed Manufacturers – Microcontroller

Architectural Overview
– Separate 16x8 transmit (TX) and 16x12 receive (RX) FIFOs to reduce CPU interrupt service
loading
– Programmable baud-rate generator with fractional divider
– Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
– FIFO trigger levels of 1/8, ¼, ½, ¾, and 7/8
– Standard asynchronous communication bits for start, stop, and parity
– False-start-bit detection
– Line-break generation and detection
■ Analog Comparators
– Three independent integrated analog comparators
– Configurable for output to: drive an output pin or generate an interrupt
– Compare external pin input to external pin input or to internal programmable voltage reference
■ I²C
– Master and slave receive and transmit operation with transmission speed up to 100 Kbps in
Standard mode and 400 Kbps in Fast mode
– Interrupt generation
– Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
■ PWM
– Three PWM generator blocks, each with one 16-bit counter, two comparators, a PWM
generator, and a dead-band generator
– One 16-bit counter
• Runs in Down or Up/Down mode
• Output frequency controlled by a 16-bit load value
• Load value updates can be synchronized
• Produces output signals at zero and load value
– Two PWM comparators
• Comparator value updates can be synchronized
• Produces output signals on match
– PWM generator
