ST7: Flash and ROM, 8-bit Integrated Solutions
ST’s 8-bit ST7 family includes a wide range of Flash and ROM devices built around an enhanced industry-standard CISC (Complex Instruction Set Computer) architecture. This technology makes it possible to effortlessly reach the highest code efficiency, whether programming in C or in Assembler. The software-configurable nested-interrupt capability further reinforces ST7's strengths in real-time applications. Integrated analog features, such as a low-voltage detector for fully secured start-up without any external components and an integrated 1% RC (Resistor-Capacitor) oscillator, considerably slash application costs.

The ST7 family ranges from 1KB single voltage Flash to fully compatible 60KB Flash and ROM products with or without electronically erasable data, housed in 8- to 80-pin packages, ensuring continuity of the previous generations and securing full software and hardware compatibility. Peripheral options include 10-bit multi-channel ADC, SCI, SPI, I²C, USB and CAN interfaces, as well as a variety of 8-bit and 16-bit timers with PWM (Pulse Width Modulation) capabilities.

The market-proven technology, coupled with the robustness of the embedded Flash (25 years at 85°C), makes ST7 devices a safe and optimum-performance choice for the 8-bit general-purpose microcontroller market.
