ST7FLIT15BF1M6 [STMicroelectronics]

ST7FLIT15BF1M6 Description

The ST7 microcontroller series includes the ST7FLIT15BF1M6. Every ST7 device is built around an 8-bit core that is an 8-bit industry standard and has an improved instruction set.

With byte-by-byte In-Circuit Programming (ICP) and In-Application Programming (IAP) functionality, the ST7FLIT15BF1M6 has FLASH memory.

The ST7FLIT15BF1M6 device can be set to WAIT, SLOW, or HALT mode by software, which reduces power consumption when the program is inactive or in standby condition.

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.
