Stellaris^® LM3S828 Microcontroller
– 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
■ Power
– On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
– Low-power options on controller: Sleep and Deep-sleep modes
– Low-power options for peripherals: software controls shutdown of individual peripherals
– User-enabled LDO unregulated voltage detection and automatic reset
– 3.3-V supply brown-out detection and reporting via interrupt or reset
■ Flexible Reset Sources
– Power-on reset (POR)
– Reset pin assertion
– Brown-out (BOR) detector alerts to system power drops
– Software reset
