Description
The Stellaris® LM3S6420 microcontroller is based on the ARM® Cortex-M3 controller core operating at up to 25 MHz, with 96 kB flash and 32 kB SRAM.The LM3S6420 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, an SSI / SPI controller, and a UART.Finally, the LM3S6420 microcontroller provides a 24-bit systick timer, 3 32-bit or 6 16-bit general-purpose timers, a watchdog timer, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 46 GPIOs.
32-bit ARM® Cortex™-M3 25-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), and Thumb-2 instruction set
Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
96 KB single-cycle flash and 32 KB single-cycle SRAM
23-46 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration
ARM FiRM-compliant Watchdog Timer ; plus three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers/counters and can be configured to operate independently
10-bit Analog-to-Digital Converter (ADC) withanalog input channels and a sample rate ofsamples/second
Fully programmable 16C550-type UART with IrDA support
Synchronous Serial Interface (SSI), supporting operation for Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces
Highly configurable 10/100 Ethernet Controller that conforms to the IEEE 802.3-2002 specification with full- and half-duplex modes for both 100 Mbps and 10 Mbps operation, and automatic MDI/MDI-X cross-over correction
Two integrated analog comparators configurable for output to drive an output pin or generate an interrupt
Industrial and extended temperature RoHS-compliant 100-pin LQFP package and industrial-range RoHS-compliant 108-ball BGA package
