32-Bit MCU Family Adds Thirteen Devices

Adding to the Stellaris family of microcontrollers are 13 32-bit devices that offer up to 64 KB of single-cycle flash, 8 KB of single cycle SRAM, speeds up to 50 MHz, and up to eight 10-bit a/d converter channels delivering up to 1 Msamples/s. Two of the devices also include quadrature encoder input capabilities in their motion-control units. Other features include, depending on the device, SSI, GPIOs, a watchdog timer and up to seven general-purpose timers, up to two UARTs, I2C, and up to six PWM waveform generators. In terms of support, the company's development kit covers the entire Stellaris family. It is a modular design with a daughter board for each family member and a common motherboard. The kit comes ready-to-go with software and tools designed to get users running in 10 minutes or less. Pricing for the 13 MCUs ranges from $3.94 to $5.47 each/10,000 and for the development kit is $249. LUMINARY MICRO INC., Austin, TX. (512) 279-8800.
