  • Power-Up Considerations
    are discussed for. problematic situation. The POR pulse comes when VDD. power-up situations where the PIC16C5X's internal cir-. is about 1.5V. Most CMOS logic, including the start-up. cuitry cannot provide the reset. timer, starts functioning between 1.5V to 2.0V. When. the start-up timer times out
  • Logic Powered Serial EEPROMs
    , determines when it needs. current across all temperature ranges to power a SEE. to communicate with the memory device, then acts. using the POWER PORT technique. accordingly. Any standard wake-up sequence will. Figure. 5 shows the connection scheme for the. accomplish this task. The wake-up code
  • Digital I/O Survival Kit
    protection against occasional transients, but are not intended to dissipate significant amounts. of energy. Signals far outside TTL limits can damage the board and/or the signal source. Therefore, it's important. to use proper interfacing when dealing with non-TTL logic levels. Figure 5. CMOS-to-TTL
