Advantages of GL640USB
Advantage
Description
EMI consideration
1. Operates at 12MHz frequency to reduce EMI radiation
2. Slew rate controlled output pads:
All the transition on output pads are well controlled to reduce the EMI radiation.
Cost Saving
1. Provide clock output, no other crystal required. The clock frequency can be 24, 16, 12,
8, 6 MHz
2. Build in power-on reset circuit. No reset circuit required.
3. Provide 3.3V output to pull-up USB bus
Flexibility
1.
Provide self-Isolation capability. With this capability, a device can be designed to
support both EPP and USB interface.
2.
Provide additional 7 GPIO pins and 4 GPI pins. These pins can be used as testing
purpose, status indication, product selection, …and so on.
3.
Customized firmware: Contains a RISC controller with 2K ROM, user can
developing its own firmware to achieve best performance and satisfy special
applications
4.
Support 93C46 to provide external VID and PID
Performance
1. Build in hardware EPP engine and 2 sets of 64 byte ping-pong FIFO, the performance
for Bulk transfer will be up to 1.1 Mbytes /sec
2. Balanced architecture: Both the Bulk-In and Bulk-Out can achieve 1.1 Mbytes/sec
transfer rate.
