ST72324LK6数据手册ST中文资料规格书

描述 Description

The ST72F324L and ST72324BL devices are members of the ST7 microcontroller family designed for mid-range applications running at 3.3V. 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, 2 general purpose timers, an SPI interface and an SCI interface.
For power economy, microcontroller can switch dynamically into WAIT, SLOW, ACTIVE-HALT or HALT mode when the application is in idle or stand-by state.
Typical applications are consumer, home, office and industrial products.
