ST7MC2R6 8位微控制器与嵌套中断,Flash,10位ADC, 无刷电机控制,五个计时器的SPI

The ST7MCx device is member of the ST7 microcontroller family designed for mid-range applications with a Motor Control dedicated peripheral.All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set and are available with FLASH, ROM or FASTROM program memory.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 stand-by 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.

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 ST7ICC Protocol Reference Manual.
