LM3S613 Datasheet, PDF (32/591 Pages) List of Unclassifed Manufacturers – Microcontroller

Architectural Overview
– 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
■ I²C
– Devices on the I²C bus can be designated as either a master or a slave
• Supports both sending and receiving data as either a master or a slave
• Supports simultaneous master and slave operation
– Four I²C modes
• Master transmit
• Master receive
• Slave transmit
• Slave receive
– Two transmission speeds: Standard (100 Kbps) and Fast (400 Kbps)
– Master and slave interrupt generation
• Master generates interrupts when a transmit or receive operation completes (or aborts
due to an error)
• Slave generates interrupts when data has been sent or requested by a master
– Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
■ Analog Comparators
– One integrated analog comparator
– Configurable for output to drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
– Compare external pin input to external pin input or to internal programmable voltage reference
– Compare a test voltage against any one of these voltages
• An individual external reference voltage
• A shared single external reference voltage
• A shared internal reference voltage
■ PWM
