Two new members of the tinyAVR family of flash microcontrollers are targeted at portable and battery-powered applications. The tiny13 and tiny2313 include an integrated brown-out detector and on-chip calibrated RC oscillator. They can operate with a supply voltage as low as 1.8V. The tiny2313 features 2K bytes of self-programming flash memory plus 128 bytes of EEPROM and SRAM and 18 I/O lines. The tiny13 has half the memory density and I/O lines and additionally boasts a 4-channel, 10-bit A/D converter.
An on-chip debug facility called debugWIRE enables designers to perform debugging on the finished product. It uses the Reset line for electrical connection to avoid having to sacrifice I/O capabilities for debug.
Evaluation tools are available now. The STK500 starter kit ($79) contains the hardware necessary to evaluate programs and test the capabilities of the microcontrollers. Available today, with volume production expected in Q1, 2004, the tiny13 is priced at $0.70 and the tiny2313 at $0.99 in 10K quantities.
