Description
The ST72324Bxx devices are members of the ST7 microcontroller family designed for mid-
range applications running from 3.8 to 5.5 V. Different package options offer up to 32 I/O
pins.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced
instruction set and are available with Flash or 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, an SPI
interface and an SCI 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.
