LM3S3749 Datasheet, PDF (45/898 Pages) Texas Instruments – Stellaris® LM3S3749 Microcontroller

Stellaris® LM3S3749 Microcontroller
– Programmable data frame size from 4 to 16 bits
– Internal loopback test mode for diagnostic/debug testing
■ I²C
– Two I²C modules, each with the following features:
– 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
■ USB
– Standards-based
– USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) operation
– USB Device or Host mode
– Integrated PHY
– 4 transfer types: Control, Interrupt, Bulk, and Isochronous
– 8 endpoints
• 1 dedicated control IN endpoint and 1 dedicated control OUT endpoint
• 3 configurable IN endpoints and 3 configurable OUT endpoints
– 2 KB dedicated endpoint memory
• Direct memory access (DMA)
