STMicroelectronics extends ST7 USB Flash family

STMicroelectronics has expanded its line of USB microcontrollers with the introduction of new products in the ST7263B series. The series is used in a range of USB-based peripheral products such as game pads, keyboards, mice, UPS and other industrial, computer and consumer applications. The USB interface supports the USB 2.0 Low-Speed protocol and is compliant with the Human Interface Device (HID) 1.0 specification.

The ST7263B brings a 32-kb, high-density Flash memory variant to the existing 4-kbyte, 8-kbyte, and 16-kbyte devices. For secure applications, the user memory code can be locked using the read/write protection feature. The family supports the Device Firmware Update (DFU) class specification which allows the Flash memory content to be upgraded through the USB line. This means that new firmware can be downloaded directly from the host to the USB product for field upgrades of application software.

A range of package options is available, including SO24, TQFP48 7x7mm, SO34, and SDIP32, and devices can also be supplied in die form, making ST’s MCU solution suitable for a range of scalable and cost-sensitive applications.
