PL23D3   USB HID to SPI Bridge Controller

The PL23D3 is a high performance single-chip USB HID to SPI bridge controller for connecting various SPI interface devices to any Universal Serial Bus (USB) capable host. The PL23D3 implements the standard USB Human Interface Device (HID) device class which is natively supported in most operating systems; so the PL23D3 does not need any custom driver installation. The operating system or USB host communicates with the PL23D3 through HID application software developed based on Prolific Windows/Mac/Linux DLL libraries.

The PL23D3 is designed to support a wide-range of SPI domain including portable, embedded, industrial, consumer devices. With very small power consumption in either operating or suspend mode, the PL23D3 is perfect for self-powered operation and can reserve power for the attached SIP devices. Flexible signal voltage option allows the PL23D3 to connect directly to SPI devices with 5V~1.8V signals.
