15 / 40 page  Copyright © Future Technology Devices International Limited 15 FT232RN USB UART IC Datasheet Version 1.0 Document No.: FT_001521 Clearance No.: FTDI#571 5 Devices Characteristics and Ratings 5.1 Absolute Maximum Ratings The absolute maximum ratings for the FT232RN devices are as follows. These are in accordance with the Absolute Maximum Rating System (IEC 60134). Exceeding these may cause permanent damage to the device. Parameter Value Units Storage Temperature -65 to 150 °C Floor Life (Out of Bag) At Factory Ambient (30°C / 60% Relative Humidity) 168 (IPC/JEDEC J-STD-033A MSL Level 3 Compliant) * Hours Ambient Temperature (Power Applied) -40 to 85 °C VCC Supply Voltage -0.5 to +6.00 V DC Input Voltage – USBDP and USBDM -0.5 to +3.8 V DC Input Voltage – High Impedance Bidirectional -0.5 to + (VCC +0.5) V DC Input Voltage – All Other Inputs -0.5 to + (VCC +0.5) V DC Output Current – Outputs 24 mA DC Output Current – Low Impedance Bidirectional 24 mA Power Dissipation (VCC = 5.25V) 500 mW Table 5.1 Absolute Maximum Ratings * If devices are stored out of the packaging beyond this time limit the devices should be baked before use. The devices should be ramped up to a temperature of +125°C and baked for up to 17 hours. 5.2 DC Characteristics DC Characteristics (Ambient Temperature = -40°C to +85°C) Parameter Description Minimum Typical Maximum Units Conditions VCC1 VCC Operating Supply Voltage 3.3 --- 5.25 V VCC2 VCCIO Operating Supply Voltage 1.8 --- 5.25 V Icc1 Operating Supply Current --- 15 --- mA Normal Operation Icc2 Operating Supply Current 50 70 100 μA USB Suspend 3V3 3.3v regulator output 3.0 3.3 3.6 V Table 5.2 Operating Voltage and Current Parameter Description Minimum Typical Maximum Units Conditions Voh Output Voltage High 3.2 4.1 4.9 V I source = 2mA Vol Output Voltage Low 0.3 0.4 0.6 V I sink = 2mA Vin Input Switching Threshold 1.0 1.2 1.5 V ** VHys Input Switching Hysteresis 20 25 30 mV ** Table 5.3 UART and CBUS I/O Pin Characteristics (VCCIO = +5.0V, Standard Drive Level) |
