The ST7260xx is an STMicroelectronics low speed USB 8-bit MCU family with high density Flash (HDFlash), FastROM with readout and write protection, in-application programming (IAP) and in-circuit programming (ICP), 384 bytes RAM memory (128-byte stack), 12 or 24 MHz oscillator, RAM Retention mode, optional low voltage detector (LVD) and other features.
The ST7260xx devices are members of the ST7 microcontroller family designed for USB applications running from 4.0 to 5.5 V. All devices are based on a common industry-standard 8-bit core and are available with Flash program memory ranging from 4 to 8 Kbytes. The architecture offers both power and flexibility to software developers, enabling the design of highly efficient and compact application code.
Typical applications include consumer, home, office, and industrial products. The on-chip peripherals include a low-speed USB interface compliant with USB 1.5 Mbps specifications and an asynchronous SCI interface. For power economy, the microcontroller can switch dynamically into Slow, Wait, Active Halt, or Halt modes when the application is in an idle or stand-by state.
