ST72323L 8位微控制器,4/8 Kbyte ROM,10位ADC,SPI接口
ST72323L and ST72323 ROM devices are members of the ST7 microcontroller family designed for the 3 V and 5 V operating range.
- The 32/34-pin (K) devices are designed for mid-range applications
- The 42/44/48-pin (J and C) devices target the same range of applications requiring more than 24 I/O ports.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with ROM program memory. The ST7 family architecture offers both power and flexibility to software developers, enabling the design of highly efficient and compact application code.
The on-chip peripherals include an A/D converter, two general purpose timers and an SPI interface. For power economy, the microcontroller can switch dynamically into, Slow, Wait, Active Halt or Halt mode when the application is in idle or stand-by state. Typical applications include consumer, home, office and industrial products.
