The ST7L05 is a member of the ST7 microcontroller family suitable for automotive applications. All ST7 devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set. The ST7L05 features Flash memory with byte-bybyte In-Circuit Programming (ICP) and In-Application Programming (IAP) capability. Under software control, the ST7L05 devices 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 x 8 unsigned multiplication and indirect addressing modes.
