150 / 163 page  Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC CL RC632 150 Confidential 22.4 Pin Characteristics 22.4.1 INPUT PIN CHARACTERISTICS Pins D0 to D7, A0, and A1 have TTL input characteristics and behave as defined in the following table. SYMBOL PARAMETER CONDITIONS MIN MAX UNIT ILeak Input Leakage Current -1.0 +1.0 µA CMOS: DVDD < 3.6 V 0.35 DVDD 0.65 DVDD V VT Threshold TTL: 4.5 < DVDD 0.8 2.0 V Table 22-4: Standard Input Pin Characteristics The digital input pins NCS, NWR, NRD, ALE, A2, and MFIN have Schmitt-Trigger characteristics, and behave as defined in the following table. SYMBOL PARAMETER CONDITIONS MIN MAX UNIT ILeak Input Leakage Current -1.0 +1.0 µA TTL: 4.5 < DVDD 1.4 2.0 V VT+ Positive-Going Threshold CMOS: DVDD < 3.6 V 0.65 DVDD 0.75 DVDD V TTL: 4.5 < DVDD 0.8 1.3 V VT- Negative-Going Threshold CMOS: DVDD < 3.6 V 0.25 DVDD 0.4 DVDD V Table 22-5: Schmitt-Trigger Input Pin Characteristics Pin RSTPD has Schmitt-Trigger CMOS characteristics. In addition, it is internally filtered with an RC-low- pass filter, which causes a relevant propagation delay for the reset signal: SYMBOL PARAMETER CONDITIONS MIN MAX UNIT ILeak Input Leakage Current -1.0 +1.0 µA VT+ Positive-Going Threshold CMOS: DVDD < 3.6 V 0.65 DVDD 0.75 DVDD V VT- Negative-Going Threshold CMOS: DVDD < 3.6 V 0.25 DVDD 0.4 DVDD V tRSTPD,p Propagation Delay 20 µs Table 22-6: RSTPD Input Pin Characteristics The analog input pin RX has the following input capacitance: SYMBOL PARAMETER CONDITIONS MIN MAX UNIT CRX Input Capacitance 15 pF Table 22-7: RX Input Capacitance The analog input pin RX has the following input voltage range: SYMBOL PARAMETER CONDITIONS MIN MAX UNIT VIN,RX Dynamical Voltage input range AVDD=5V, T=25°C 1,1V 4,4 V Table 22-8: RX Input voltage range |
