ST7FLITE09Y0B6 [STMicroelectronics]

ST7FLITE09Y0B6 Description

The ST7FLITE09Y0B6 belongs to the ST7 family of microcontrollers. Every ST7 device is built around an 8-bit core that is the 8-bit industry standard and has an improved instruction set.

The FLASH memory in the ST7LITE0x and ST7SUPERLITE supports byte-by-byte In-Circuit Programming (ICP) and In-Application Programming (IAP).

The ST7LITE0x and ST7SUPERLITE devices can be set to WAIT, SLOW, or HALT mode under software control, which lowers the power consumption when the application is idle or in the standby state.

Software developers have power and flexibility because of the ST7's increased instruction set and addressing modes, which allow for the creation of incredibly efficient and small application code. All ST7 microcontrollers include actual bit manipulation, 8x8 unsigned multiplication, and indirect addressing modes in addition to ordinary 8-bit data management.
