Lexington, Mass. STMicroelectronics has launched a low-cost, complete evaluation and development package for the company's tiny 8-pin versions of the ST7Lite microcontroller family, with a recommended resale
price of just $12.00.
The 'ST7Ultralite Primer' is a compact USB-powered tool based on the ST7FLITEUS MCU, pre-programmed with a real-world software
application which is designed to demonstrate all of the MCU's main features
and peripherals. The tool extends extends ST's existing line with a complete,
ultra-low-cost evaluation and development tool based on a proven tool
solution, the Raisonance RIDE and RLink for the ST7, microPSD, STR7 and STR9
families " and has been tailored specifically to the ST7FLITEUS.
The Primer plugs directly into the USB port of a host PC, and includes ST's
UltraliteMusic application to highlight features such as the internal RC
oscillator, 10-bit Analog to Digital Converter, 12-bit autoreload
timer with PWM, and low voltage and auxiliary voltage detectors. This light
sensor and buzzer application plays five musical selections; changes in
ambient light intensity cause it to step through the tunes. If the Primer is
unplugged from the USB port and then reconnected, the music continues from
where it left off thanks to the MCU's low voltage detection.
Users can modify UltraliteMusic, for which C source files are provided
and can create new applications using the C compiler and RIDE software
toolset included with the kit. The Raisonance uRLink in-circuit debugger and
programmer enable users to run, modify and debug application code on the
host PC through the USB connection. Also included are the RBuilder
application builder for easy configuration of the ST7 peripherals and
generation of source code, and the RFlasher programming interface.
The ST7FLITEUS is delivered in a 4.5mm x 3.5mm DFN8 package. It integrates key system peripherals of
the popular and easy-to-use ST7Lite Flash MCU family, and is ideal for
cost-sensitive applications such as security, lighting, power control, small
appliances, sensors and simple motor control.
Primer is available now, ST part number ST7FUS-PRIMER, priced at $12.00 per
