Description

The ST72512R devices are members of the ST7 microcontroller family.They can be grouped as follows:
  ST72512Rdevices are designed for mid-range applications with a CAN bus interface (Controller Area Network)
  ST72512R devices target the same range of applications but without CAN interface.

All devices of the ST72512R are based on a common industrystandard 8-bit core,featuring an enhanced instruction set.

Under software control,all devices can be placed in WAIT,SLOW,ACTIVE-HALT or HALT mode,reducing power consumption when the application is in idle or standby state.

The enhanced in structionset 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.
