LM3S3748 Datasheet, PDF (30/753 Pages) List of Unclassifed Manufacturers – Microcontroller

Architectural Overview
– Direct memory access (DMA)
■ USB
– Standards-based universal serial bus controller
– USB 2.0 full-speed (12 Mbps) operation
– Flexible configuration option
• USB Device mode
• USB Host mode
– Integrated PHY
– 4 transfer types: Control, Interrupt, Bulk, and Isochronous
– 1 dedicated bi-directional control endpoint
– 3 Receive and 3 Transmit configurable endpoints
– 4 KB dedicated endpoint memory
• Direct memory access (DMA)
• One endpoint may be defined for double-buffered 1023-byte isochronous packet size
■ ADC
– Single- and differential-input configurations
– Eight 10-bit channels (inputs) when used as single-ended inputs
– 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
– Each sequence triggered by software or internal event (timers, analog comparators, PWM
or GPIO)
– On-chip temperature sensor
■ Analog Comparators
– Two independent integrated analog comparators
– Configurable for output to: drive an output pin or generate an interrupt
– 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
