ST7260E1中文资料LOW SPEED USB 8-BIT MCU FAMILY WITH UP TO 8K FLASH/ROM AND SERIAL COMMUNICATION INTERFACE (SCI)数据手册ST规格书

描述 Description

The ST7260xx devices are members of the ST7 microcontroller family designed for USB applications running from 4.0 to 5.5 V. Different package options offer up to 19 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 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 a low speed USB interface and an asynchronous 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.
