Description
I2C, SPI, and GPIO Translator/Level Shifter
The I2C Translator/Level Shifter incorporates a dual-channel, bidirectional logic-level translator with the level shifting necessary to allow data transfer in a multi-voltage system. Connecting this level translator to the USB-to-I2C hardware, allows the user to extend the lower voltage operating range from the normal 3.3V minimum, down to 0.9V minimum. In order to improve signal integrity, rise and fall time accelerators are included to improve rise time, especially in highly loaded systems. Standard, fast, and fast-mode plus speeds are supported.
The SPI translator extends the lower operating range of 3.3V down to 1.2V, with a maximum clock speed of 12 MHz.
The general purpose input and output found on the USB-to-I2C hardware also are connected to a level shifter on the hardware extending the lower voltage operating range down to 0.9V
The Translator/Level Shifter connects directly to the USB-to-I2C hardware through the 14-pin cable connectors.
