Product overview
Description
The ST7L3x is a member of the ST7 microcontroller family suitable for automotive applications. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.
The ST7L3x features Flash memory with byte-by-byte in-circuit programming (ICP) and in-application programming (IAP) capability.
Under software control, the ST7L3x 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.
