Microcontrollers: 8-bit USB Microcontrollers LC871 Series

The LC871 Series are 8-bit microcontrollers with on-chip flash memory that employ USB (Universal Serial Bus) interfaces, which are rapidly increasing in popularity as I/O interfaces for personal computers.

Flash microcontrollers (microcontrollers with on-chip flash memory) can enable the new product development period to be reduced and mass production to be commenced at an earlier stage, and also display superior maintainability. The usefulness of these microcontrollers is widely recognized, and their market is rapidly expanding.

The USB standard is, on the other hand, presently attracting considerable attention in the market as a superior PC interface system, answering demands for ease of connection, low cost, and higher communication speeds.

Responding to increased market needs, SANYO has brought these technologies together to produce a flash microcontroller with an on-chip USB interface.

LC871 Series is compliant with USB Versions 1.1 and 2.0, and use SANYO's proprietary flash onboard reprogramming system to enable software to be downloaded from a PC via the USB interface and the microcontroller to be reprogrammed while installed in an end product. In addition, a USB regulator and system clock PLL on the same chip make it possible to reduce the number of components used in end products.

The LC871 Series are compliant with USB Versions 1.1 and 2.0 (low-speed USB-compliant: LC87F1364A; full-speed USBcompliant:LC87F10C8A, LC87F14C8A, LC87F16C8A, LC87F1964A, LC87F1A32A, LC87F1G64A), and is provided with a wide rangeof features including onboard reprogramming, self-reprogramming in 128-byte units, a 3.3V regulator for USB port voltage, and high-capacity FIFO (max. 8KB).
