Microcontrollers optimised for small-scale, cost sensitive applications

19 April 2006 DSP, Micros & Memory

STMicroelectronics' ST7Lite series consists of entry-level standard 8-bit Flash microcontroller devices ideal for cost-sensitive applications. The series is designed to provide high flexibility at every stage of the product cycle, from first prototype to production logistics. This ensures reduced cost of ownership and fast time to market, it claims.

The ST7Lite series come with a variety of integrated peripherals that make them versatile enough for a wide range of applications. All MCUs use the same single-voltage Flash technology and are programmed using the same techniques and tools. They also share a common emulator and software development platform. This family is designed for ease of use with silicon, software, development tools, reference designs and service, in one package.

Key features and benefits include:

* 8-bit microcontroller with more on-chip functionalities; makes applications smaller and easier to design.

* Highly-accurate internal 1 MHz RC oscillator.

* Data EEPROM.

* Trimmable internal low-voltage detector; eliminates need for external power-on and brown-out management circuits.

* Read-out protection prevents software piracy.

* Fast A/D converter (3,5 ms conversion time at 8 MHz) including op-amp.

* Single-voltage Flash for fast programming.

* Fast and flexible timers for PWM generation, output compare and input capture.

Typical applications include: lighting; alarms; home appliances; sensors; airconditioning; metering; touch control; motor control; DC/DC converters; toys. For fast and easy development, ST offers a wide range of state-of-the-art development tools.
