LM3S608 Datasheet, PDF (21/416 Pages) List of Unclassifed Manufacturers – Microcontroller

LM3S608 Microcontroller
– 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
■ 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
– Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
– Programmable data frame size from 4 to 16 bits
– Internal loopback test mode for diagnostic/debug testing
■ UART
– Two fully programmable 16C550-type UARTs
– 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, 1/4, 1/2, 3/4, and 7/8
– Standard asynchronous communication bits for start, stop, and parity
– False-start-bit detection
– Line-break generation and detection
■ ADC
– Single- and differential-input configurations
– Eight 10-bit channels (inputs) when used as single-ended inputs
– Sample rate of 500 thousand samples/second
– Flexible, configurable analog-to-digital conversion
– Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
– Each sequence triggered by software or internal event (timers, analog comparators, or GPIO)
