Products - GPUSB101A

General Description

The GPUSB101A embedded an 8-bit processor, 16K bytes OTP ROM, 256 bytes working SRAM, six 64 bytes buffer SRAM, 2 set 12-bit timers, and 20 general I/Os. The general I/Os can be programmed as parallel bus or SPI. There are three main functions for the bridge IC.

• USB to parallel bus
• USB to SPI
• Parallel bus to SPI
