ST7-OT4

The ST7-OT4 is a designation used by STMicroelectronics, referring to a specific configuration or variant within their ST7 microcontroller family. The ST7 microcontroller family is an 8-bit microcontroller architecture designed for a range of embedded applications. The suffix "-OT4" typically indicates specific characteristics related to memory size, packaging, operating temperature range, or other key features of the microcontroller.

Generally, suffixes like "-OT4" are used to differentiate specific product offerings within the larger ST7 family. To determine the precise meaning of "-OT4" for a specific ST7 microcontroller, one would need to consult the official datasheets and documentation provided by STMicroelectronics. These documents will detail the specific parameters and specifications of the ST7 microcontroller with the "-OT4" suffix, outlining differences from other ST7 variants. The details would include aspects such as program memory size (ROM, Flash), RAM size, package type (e.g., DIP, SOIC, QFP), temperature range (e.g., industrial, automotive), and any specific peripheral configurations or features that distinguish it from other ST7 models. Without consulting the official documentation, pinpointing the precise differences signified by "-OT4" is impossible.
