Product Features

• 32-bit ARM® Cortex™-M3 v7M architecture optimized for small-footprint embedded applications
• Thumb®-compatible Thumb-2-only instruction set
• 25-MHz operation
• Hardware-division and single-cycle-multiplication
• Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt handling
• 24 interrupt channels with eight priority levels
• 16 KB single-cycle flash with two forms of flash protection on a 2-KB block basis
• 4 KB single-cycle SRAM
• Three timers, each of which can be configured: as a single 32-bit timer, as a dual 16-bit timer with capture and simple PWM modes, or to initiate an ADC event
• Real-Time Clock (RTC) capability
• 32-bit down counter with a programmable load register
• Separate watchdog clock with an enable
• Programmable interrupt generation logic
• Lock register protection from runaway software
• Reset generation logic with an enable/disable Synchronous Serial Interface (SSI)
• Programmable interface operation for Freescale SPI, National Semiconductor MICROWIRE™, or Texas Instruments synchronous serial
• Master or slave operation
• 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 Analog-to-Digital Converter (ADC)
• Single- and differential-input configurations
• Four 10-bit channels (inputs) when used as singleended inputs
• Sample rate of 250 thousand samples/second
• Flexible, configurable analog-to-digital conversion
• 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
• Two motion-control PWM outputs
• Each PWM generator block has one 16-bit counter, two comparators, a PWM generator, and a deadband generator
• Output control block with PWM output enable of each PWM signal
• Can initiate an ADC sample sequence
• 7 to 32 GPIOs, depending on user configuration
• Programmable interrupt generation
• Can initiate an ADC sample sequence
• Programmable drive strength and slew rate
• On-chip Linear Drop-Out (LDO) voltage regulator, with programmable output user-adjustable from 2.25 V to 2.75 V
• Low-power options on processor: Sleep and Deepsleep 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 brownout detection and reporting via interrupt or reset
• On-chip temperature sensor
• Six reset sources
• IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
