11 / 12 page 11 Specification Absolute Maximum Ratings Exceeding the maximum rating can result in device damage. Operation of the device outside the operating limits is not implied. Supply voltage -0.3 to 7.0V Input voltage at any pin (ref V SS = 0V) -0.3 to (V DD + 0.3V) Sink/source current (supply pins) +/- 30mA (other pins) +/- 20mA Total device dissipation @ T AMB 25°C 800mW Max. Derating 10mW/°C Operating temperature range: FX489DW/P -40°C to +85°C Storage temperature range: FX489DW/P -40°C to +85°C Operating Limits All device characteristics are measured under the following conditions unless otherwise specified: V DD = 5.0V, T AMB = 25°C. Xtal/Clock Frequency = 4.096MHz. Data Rate = 8000 bits/sec. Noise Bandwidth = Bit Rate Characteristics See Note Min. Typ. Max.

Not including current drawn from the FX489 pins by external circuitry. See Absolute Maximum Ratings. 2. For V IN in the range VSS to VDD. 3 For a load of 10k Ω or greater. Tx PS input at logic “0”; Tx Enable = “1”. 4. Data pattern of “1111000011110000 ..” 5. Measured between the rising edge of ‘Tx Clock’ and the centre of the corresponding bit at ‘Tx Out.’ 6. Time between the falling edge of ‘Tx PS’ and the ‘Tx Out’ voltage stabilising to normal output levels. 7. For a load of 10k Ω or greater. Rx PS input at logic “0”. 8. For optimum performance, measured at the ‘Rx Feedback’ pin for a “1111000011110000 ...” pattern. 9. Measured between the centre of bit at ‘Rx Signal In’ and corresponding rising edge of the ‘Rx Clock’. 10. Timing for an external clock input to the Xtal/Clock pin. |
