Product data sheet Rev. 3.3 — 4 July 2016 11 of 55 NXP Semiconductors PN7150 Full NFC Forum-compliant controller with integrated firmware At application level, the PN7150 will continuously switch between different states to optimize the current consumption (polling loop mode). Refer to Table 1 for targeted current consumption in here described states. The PN7150 is designed to allow the host controller to have full control over its functional states, thus of the power consumption of the PN7150 based NFC solution and possibility to restrict parts of the PN7150 functionality. 10.1.2.1 Monitor state In Monitor state, the PN7150 will exit it only if the battery voltage recovers over the critical level. Battery voltage monitor thresholds show hysteresis behavior as defined in Table 27. 10.1.2.2 Hard Power Down (HPD) state The Hard Power Down state is entered when VDD(PAD) and VBAT are high by setting VEN voltage < 0.4 V. As these signals are under host control, the PN7150 has no influence on entering or exiting this state. 10.1.2.3 Standby state Active state is PN7150’s default state after boot sequence in order to allow a quick configuration of PN7150. It is recommended to change the default state to Standby state after first boot in order to save power. PN7150 can switch to Standby state autonomously (if configured by host). In this state, PN7150 most blocks including CPU are no more supplied. Number of wake-up sources exist to put PN7150 into Active state: • I2C-bus interface wake-up event • Antenna RF level detector • Internal timer event when using polling loop (380 kHz Low-power oscillator is enabled) Table 8. PN7150 power states Power state name Description Monitor The PN7150 is supplied by VBAT which voltage is below its programmable critical level, VEN voltage > 1.1 V and the Monitor state is enabled. The system power mode is Power Off mode. Hard Power Down The PN7150 is supplied by VBAT which voltage is above its programmable critical level when Monitor state is enabled and PN7150 is kept in Hard Power Down (VEN voltage is kept low by host or SW programming) to have the minimum power consumption. The system power mode is in Power Off. Standby The PN7150 is supplied by VBAT which voltage is above its programmable critical level when the Monitor state is enabled, VEN voltage is high (by host or SW programming) and minimum part of PN7150 is kept supplied to enable configured wake-up sources which allow to switch to Active state; RF field, Host interface. The system power mode is Full power mode. Active The PN7150 is supplied by VBAT which voltage is above its programmable critical level when Monitor state is enabled, VEN voltage is high (by host or SW programming) and the PN7150 internal blocks are supplied. 3 functional modes are defined: Idle, Target and Initiator. The system power mode is Full power mode. |
