The ST7LITE0x and ST7SUPERLITE (ST7LITESx) are members of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.
The ST7LITE0x and ST7SUPERLITE feature FLASH memory with byte-by-byte In-Circuit Programming (ICP) and In-Application Programming (IAP) capability.
Under software control, the ST7LITE0x and ST7SUPERLITE 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, 8x8 unsigned multiplication and indirect addressing modes.
For easy reference, all parametric data are located in section 13 on page 81.
