Flash MCUs tipped for cost-conscious products

STMicroelectronics introduces an ultralow-cost series of flash MCUs aimed at cost-sensitive products such as electric bicycles (ebikes), air conditioning, small appliances and sensors. The ST7FOX series includes devices with 2Kbyte to 8kbyte of on-chip flash memory and with eight to 32 pins, all priced below 50 cents.

Part of the ST7 family of MCUs, built on an industry-standard 8bit architecture, the ST7FOX devices achieve their low unit cost with a simplified feature set, while maintaining the benefits of a proven technology, said ST. The ST7FOX family operates at +5V (10 percent) power supply, and includes a relaxed RC oscillator that can be calibrated within the application.

The ST7FOX offers an upgrade path to the ST7Lite family, providing a scalable solution to designers. The low pricing enables designers to implement a MCU solution to replace electromechanical or logic-based control, and for the same cost as ROM devices this flash-based family will ease inventory management, said ST. A free integrated development environment (IDE) including a C compiler also minimizes development cost.

Samples are available now in: 8-pin DIP or SO-8 packaged devices with 2Kbytes of flash, and 32-pin DIP or LQFP devices with 4Kbytes of Flash.
