LM3S818 Microcontroller
Features
32-Bit RISC Performance
32-bit ARM® Cortex™-M3 v7M architecture optimized
for small-footprint embedded applications
50-MHz operation
System timer (SysTick) provides a simple, 24-bit
clear-on-write, decrementing, wrap-on-zero counter
with a flexible control mechanism
Thumb®-compatible Thumb-2-only instruction set
processor core for high code density
Integrated Nested Vectored Interrupt Controller
(NVIC) provides deterministic interrupt handling
26 interrupt channels with eight priority levels
Memory protection unit (MPU) provides a privileged
mode for protected operating system functionality
Unaligned data access enables data to be efficiently
packed into memory
Atomic bit manipulation (bit-banding) delivers
maximum memory utilization and streamlined
peripheral control
On-Chip Memory
64 KB single-cycle flash with two forms of flash
protection on a 2-KB block basis
8 KB single-cycle SRAM
General-Purpose Timers
Three General-Purpose Timer Modules (GPTM), each
configurable as one 32-bit or two 16-bit timers with
capture and simple PWM modes, or to initiate an ADC
event
Real-Time Clock (RTC) capability
Watchdog Timer
32-bit down counter with a programmable load
register
Separate watchdog clock with an enable
Programmable interrupt generation logic with interrupt
masking
Lock register protection from runaway software
Reset generation logic with an enable/disable
Synchronous Serial Interface (SSI)
Programmable interface operation for Freescale SPI,
MICROWIRE, or Texas Instruments synchronous
serial interfaces
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 allowing speeds
up to up to 3.125 Mbps
Programmable FIFO length, including 1-byte deep
operation providing conventional double-buffered
interface
FIFO trigger levels of 1/8, ¼, ½, ¾, and 7/8
Standard asynchronous communication bits for start,
stop, and parity
False-start-bit detection
Line-break generation and detection
Analog-to-Digital Converter (ADC)
Single- and differential-input configurations
Six 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
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
PWM
Three PWM generator block, each with one 16-bit
counter, two comparators, a PWM generator, and a
dead-band generator
Flexible output control block with PWM output enable
of each PWM signal
Can initiate an ADC sample sequence
Quadrature Encoder Inputs
Hardware position integrator tracks the encoder
position
