35 / 111 page  DS11597 Rev 5 35/111 SPC582B60x, SPC582B54x, SPC582B50x Electrical characteristics 37 4.9 Reset pad (PORST) electrical characteristics The device implements dedicated bidirectional reset pins as below specified. PORST pin does not require active control. It is possible to implement an external pull-up to ensure correct reset exit sequence. Recommended value is 4.7 K Ω. Figure 5. Startup Reset requirements Figure 6 describes the device behavior depending on the supply signal on PORST: 1. PORST low pulse has too low amplitude: it is filtered by input buffer hysteresis. Device remains in current state. 2. PORST low pulse has too short duration: it is filtered by low pass filter. Device remains in current state. 3. PORST low pulse is generating a reset: a) PORST low but initially filtered during at least WFRST. Device remains initially in current state. b) PORST potentially filtered until WNFRST. Device state is unknown. It may either be reset or remains in current state depending on extra condition (temperature, voltage, device). c) PORST asserted for longer than WNFRST. Device is under reset. VIL VDD PORST VIH device start-up phase VDD_POR PORST driven low by device reset forced by external circuitry PORST undriven device reset by internal power-on reset internal power-on reset |
