52 / 58 page  Philips Semiconductors Preliminary data P87LPC761 Low power, low price, low pin count (16 pin) microcontroller with 2 kbyte OTP 2002 Mar 07 49 COMPARATOR ELECTRICAL CHARACTERISTICS VDD = 3.0 V to 6.0 V unless otherwise specified; Tamb = 0 °C to +70 °C, unless otherwise specified. SYMBOL PARAMETER TEST CONDITIONS LIMITS UNIT SYMBOL PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIO Offset voltage comparator inputs1 – – ±10 mV VCR Common mode range comparator inputs 0 – VDD–0.3 V CMRR Common mode rejection ratio1 – – –50 dB Response time – 250 500 ns Comparator enable to output valid – – 10 µs IIL Input leakage current, comparator 0 < VIN < VDD – – ±10 µA NOTE: 1. This parameter is guaranteed by characterization, but not tested in production. AC ELECTRICAL CHARACTERISTICS Tamb = 0 °C to +70 °C, VDD = 2.7 V to 6.0 V unless otherwise specified; VSS = 0 V1, 2, 3 SYMBOL FIGURE PARAMETER LIMITS UNIT SYMBOL FIGURE PARAMETER MIN MAX UNIT External Clock fC 42 Oscillator frequency (VDD = 4.0 V to 6.0 V) 0 20 MHz fC 42 Oscillator frequency (VDD = 2.7 V to 6.0 V) 0 10 MHz tC 42 Clock period and CPU timing cycle 1/fC – ns fCLCX 42 Clock low-time1 fOSC = 20 MHz 20 – ns fCLCX 42 fOSC = 10 MHz 40 – ns fCHCX 42 Clock high-time1 fOSC = 20 MHz 20 – ns fCHCX 42 fOSC = 10 MHz 40 – ns Internal RC Oscillator fCCAL On-chip RC oscillator calibration2 fRCOSC = 6 MHz –1 +1 % fCTOL On-chip RC oscillator, 0 °C to +50 °C3,4 tol. fRCOSC = 6 MHz –2.5 +2.5 % fCTOL On-chip RC oscillator, 0 °C to +70 °C3 tol. fRCOSC = 6 MHz –55 +2.5 % Shift Register tXLXL 41 Serial port clock cycle time 6tC – ns tQVXH 41 Output data setup to clock rising edge 5tC – 133 – ns tXHQX 41 Output data hold after clock rising edge 1tC – 80 – ns tXHDV 41 Input data setup to clock rising edge – 5tC – 133 ns tXHDX 41 Input data hold after clock rising edge 0 – ns NOTES: 1. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins. 2. Tested at VDD = 5.0 V and room temperature. 3. These parameters are characterized but not tested. 4. +/– 2.5% accuracy enables serial communication over the UART with the internal Oscillator. 5. Min frequency at hot temperature. |
