5 / 30 page COP980CCOP981CCOP982C DC Electrical Characteristics (Continued) Note 1 Rate of voltage change must be less than 05Vms Note 2 Supply current is measured after running 2000 cycles with a square wave CKI input CKO open inputs at rails and outputs open Note 3 The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations Test conditions All inputs tied to VCC L C and G ports TRI-STATE and tied to ground all outputs low and tied to ground Note 4 Pins G6 and RESET are designed with a high voltage input network for factory testing These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC) The effective resistance to VCC is 750X (typ) These two pins will not latch up The voltage at the pins must be limited to less than 14V Note 5 To maintain RAM integrity the voltage must not be dropped or raised instantaneously AC Electrical Characteristics 0 C s TA s a70 C unless otherwise specified Parameter Condition Min Typ Max Units Instruction Cycle Time (tc) CrystalResonator or External VCC t 40V 1 DC m s (Div-by 10) 23V s VCC s 40V 25 DC m s RC Oscillator Mode VCC t 40V 3 DC m s (Div-by 10) 23V s VCC s 40V 75 DC m s CKI Clock Duty Cycle (Note 6) fr e Max 40 60 % Rise Time (Note 6) fr e 10 MHz Ext Clock 12 ns Fall Time (Note 6) fr e 10 MHz Ext Clock 8 ns Inputs tSETUP VCC t 40V 200 ns 23V s VCC s 40V 500 ns tHOLD VCC t 40V 60 ns 23V s VCC s 40V 150 ns Output Propagation Delay CL e 100 pF RL e 22 kX tPD1 tPD0 SO SK VCC t 40V 07 m s 23V s VCC s 40V 175 m s All Others VCC t 40V 1 m s 23V s VCC s 40V 25 m s MICROWIRETM Setup Time (tUWS) 20 ns MICROWIRE Hold Time (tUWH) 56 ns MICROWIRE Output Propagation Delay (tUPD) 220 ns Input Pulse Width Interrupt Input High Time tC Interrupt Input Low Time tC Timer Input High Time tC Timer Input Low Time tC Reset Pulse Width 10 m s Note 6 Parameter characterized but not production tested http www nationalcom 5 |
