ST7FLITE35F2M6

STMICROELECTRONICS  ST7FLITE35F2M6  微控制器, 8位, ST7, 8 MHz, 8 KB, 384 Byte, 20 引脚, SOIC

The ST7LITE3 is a member of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.

The ST7LITE3 features FLASH memory with byte-by-byte In-Circuit Programming ICP and In-Application Programming IAP capability.

Under software control, the ST7LITE3 device 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 131.

The devices feature an on-chip Debug Module DM to support in-circuit debugging ICD. For a description of the DM registers, refer to the ST7 ICC Protocol Reference Manual.
