The ST7FOX is a member of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.The device is positioned at the entry level of the 8-bit microcontroller range providing an attractive cost while at the same time embedding the most advanced features.The ST7FOX features Flash memory with byte-by-byte In-Circuit Programming (ICP) and InApplication Programming (IAP) capability.Under software control, the ST7FOX device can be placed in Wait, Slow, or Halt mode, reducing power consumption when the application is in idle or standby state. The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8×8 unsigned multiplication and indirect addressing modes.The ST7FOX features an on-chip Debug Module (DM) to support In-Circuit Debugging (ICD).
