Low-cost 8-bit Flash MCU family
6 February 2008, DSP, Micros & Memory

The ST7FOX series from STMicroelectronics is a new ultra-low-cost series of Flash microcontrollers (MCUs) intended for highly cost-sensitive products such as electric bicycles (ebikes), airconditioning, small appliances and sensors. The series includes devices with 2 to 8 KB of on-chip Flash memory, and with 8 to 32 pins.

Part of the ST7 family, the new devices achieve their low unit cost with a simplified feature set, while maintaining the benefits of a robust and proven technology. ST7FOX operates at +5 V, and includes a relaxed RC oscillator which can be calibrated within the application.

The CISC (complex instruction set computer) architecture allows for the production of compact code matching the small memory footprint of the family's devices, with nested interrupt management and a variety of addressing modes in the core architecture simplifying high level language coding.
