LM3S9B81 Datasheet, PDF (44/1155 Pages) Texas Instruments – Stellaris® LM3S9B81 Microcontroller

Architectural Overview
– Three CAN 2.0 A/B controllers
– USB 2.0 OTG/Host/Device
– Three UARTs with IrDA and ISO 7816 support (one UART with full modem controls)
– Two I²C modules
– Two Synchronous Serial Interface modules (SSI)
– Integrated Interchip Sound (I²S) module
■ System Integration
– Direct Memory Access Controller (DMA)
– System control and clocks including on-chip precision 16-MHz oscillator
– Four 32-bit timers (up to eight 16-bit), with real-time clock capability
– Eight Capture Compare PWM pins (CCP)
– Two Watchdog Timers
• One timer runs off the main oscillator
• One timer runs off the precision internal oscillator
– Up to 65 GPIOs, depending on configuration
• Highly flexible pin muxing allows use as GPIO or one of several peripheral functions
• Independently configurable to 2, 4 or 8 mA drive capability
• Up to 4 GPIOs can have 18 mA drive capability
■ Analog
– Two 10-bit Analog-to-Digital Converters (ADC) with 16 analog input channels and sample
rate of one million samples/second
– Three analog comparators
– 16 digital comparators
– On-chip voltage regulator
■ JTAG and ARM Serial Wire Debug (SWD)
■ 100-pin LQFP and 108-ball BGA package
■ Industrial (-40°C to 85°C) Temperature Range
The LM3S9B81 microcontroller is targeted for industrial applications, including remote monitoring,
electronic point-of-sale machines, test and measurement equipment, network appliances and
switches, factory automation, HVAC and building control, gaming equipment, motion control, medical
instrumentation, and fire and security.
