• Manufacturer Part Number: ox16c954
• Description: High Performance Quad Uart With 128-byte Fifos Intel / Motorola Bus Interface
• Manufacturer: ETC-unknow

16 O
Note: For the TQFP package, a Voltage between 3.0 to 5.25 V is possible. The I/O switching thresholds are defined for 3.0 to
3.45 V operation with VDETECT held high, and for 4.75 to 5.25V with VDETECT held low. The thresholds are not calibrated
outside these ranges, but VDETECT held high gives CMOS type I/Os that scale better with Voltage, so should be used if a
voltage between these ranges is used, but the thresholds are not guaranteed.
