For this PMIC, 0.975 V typical is acceptable and supported. 2 Applying the maximum voltage results in maximum power consumption and heat generation. A voltage set point = (Vmin + the supply tolerance) is recommended. This results in an optimized power/speed ratio. i.MX 8M Mini Applications Processor Datasheet for Consumer Products, Rev. 1, 07/2020 18 NXP Semiconductors Electrical characteristics 3 Overdrive maximum voltage includes all the nominal frequencies. 4 50% duty cycle for 5 years 5 Booting VDD_SOC at 0.800 V �5% is acceptable (Vmin = 0.760 V). Software is expected to program the VDD_SOC voltage to the typical value in this table prior to first DRAM memory access. 6 Ensure the VDD_PCI_1P8 does not have more than 40 mVpp AC power supply noise superimposed on the high power supply voltage for the PHY core (1.8 V nominal DC value). Simultaneously, the VDD_PCI_0P8 should have no more than 20 mVpp AC power supply noise superimposed on the low power supply voltage for th PHY core (0.9 V nominal DC value for the overdrive). 7 It can be min 0.78 V when supplied but not operating PCIe. 8 “EN” of TMU Enable Register (TMU_TER) is required to be always enabled for the part to operate correctly. 3.1.4 External clock sources Each i.MX 8M Mini processor has two external input system clocks: a low frequency (RTC_XTALI) and a high frequency (XTALI). The RTC_XTALI is used for low-frequency functions. It supplies the clock for wake-up circuit, power-down real time clock operation, and slow system and watch-dog counters. The clock input can only be connected to an external oscillator. RTC_XTALO should be directly connected to VDD_SNVS_0P8. The system clock input XTALI is used to generate the main system clock. It supplies the PLLs and other peripherals. The system clock input can be connected to either an external oscillator or a crystal using internal oscillator amplifier. Table 11 shows the interface frequency requirements. Table 11.

For RTC_XTALI operation, an external oscillator is necessary. RTC_XTALO should be directly connected to VDD_SNVS_0P8 when using an external 32.768 kHz oscillator.

Estimating the maximum supply currents required for power supply design is difficult because the use cases that requires maximum supply current is not a realistic use cases. To help illustrate the effect of the application on power consumption, data was collected while running consumer standard benchmarks that are designed to be compute and graphic intensive. The results provided are intended to be used as guidelines for power supply design.

The CPU can be in the power-gated state but with L2 data retained, DRAM and the bus clock are reduced. Most of the internal logic is clock gated but still remains powered. The M4 core can remain running. Compared with RUN mode, all the external power rails from the PMIC remain the same, and most of the modules still remain in their state. � SUSPEND Mode: The most efficient power saving mode where all the clocks are off and all the unnecessary power supplies are off. � SNVS Mode: This mode is also called RTC mode. Only the power for the SNVS domain remains on to keep RTC and SNVS logic alive. � OFF Mode: All power rails are off. Table 14.

It supports Asynchronous Timing mode, Source Synchronous Timing mode and Toggle Timing mode separately, as described in the following subsections. 3.9.4.1 Asynchronous mode AC timing (ONFI 1.0 compatible) Asynchronous mode AC timings are provided as multiplications of the clock cycle and fixed delay. The maximum I/O speed of GPMI in Asynchronous mode is about 50 MB/s. Figure 21 through Figure 24 depicts the relative timing between GPMI signals at the module level for different operations under Asynchronous mode.

This AC timing depends on these registers settings. In the table, AS/DS/DH represents each of these settings. 2 AS minimum value can be 0, while DS/DH minimum value is 1. 3 T = GPMI clock period -0.075 ns (half of maximum p-p jitter). 4 NF12 is guaranteed by the design. 5 Non-EDO mode. 6 EDO mode, GPMI clock 100 MHz (AS=DS=DH=1, GPMI_CTL1 [RDN_DELAY] = 8, GPMI_CTL1 [HALF_PERIOD] = 0). In EDO mode (Figure 24), NF16/NF17 are different from the definition in non-EDO mode (Figure 23). They are called tREA/tRHOH (RE# access time/RE# HIGH to output hold). The typical values for them are 16 ns (max for tREA)/15 ns (min for tRHOH) at 50 MB/s EDO mode. In EDO mode, GPMI samples NAND_DATAxx at the rising edge of delayed NAND_RE_B provided by an internal DPLL. The delay value can be controlled by GPMI_CTRL1.RDN_DELAY (see the GPMI chapter of the i.MX 8M Mini Applications Processor Reference Manual [IMX8MMRM]). The typical value of this control register is 0x8 at 50 MT/s EDO mode. But if the board delay is big enough and cannot be ignored, the delay value should be made larger to compensate the board delay. i.MX 8M Mini Applications Processor Datasheet for Consumer Products, Rev. 1, 07/2020 NXP Semiconductors 47 Electrical characteristics 3.9.4.2 Source synchronous mode AC timing (ONFI 2.x compatible) Figure 26 to Figure 28 show the write and read timing of Source Synchronous mode.

This AC timing depends on these registers settings. In the table, CE_DELAY/PRE_DELAY/POST_DELAY represents each of these settings. 2 T = tCK(GPMI clock period) �0.075 ns (half of maximum p-p jitter). For DDR Source Synchronous mode, Figure 29 shows the timing diagram of NAND_DQS/NAND_DATAxx read valid window. The typical value of tDQSQ is 0.85 ns (max) and 1 ns (max) for tQHS at 200 MB/s. GPMI will sample NAND_DATA[7:0] at both rising and falling edge of an delayed NAND_DQS signal, which can be provided by an internal DPLL. The delay value can be controlled by GPMI register GPMI_READ_DDR_DLL_CTRL.SLV_DLY_TARGET (see the GPMI chapter of the i.MX 8M Mini Applications Processor Reference Manual [IMX8MMRM]). Generally, the typical delay value of this register is equal to 0x7 which means 1/4 clock cycle delay expected. But if the board delay is big enough and cannot be ignored, the delay value should be made larger to compensate the board delay. i.MX 8M Mini Applications Processor Datasheet for Consumer Products, Rev. 1, 07/2020 50 NXP Semiconductors 3.9.4.3 ONFI NV-DDR2 mode (ONFI 3.2 compatible) Electrical characteristics 3.9.4.3.1 Command and address timing ONFI 3.2 mode command and address timing is the same as ONFI 1.0 compatible Async mode AC timing.

When encoding, the SPDIF data signal is modulated by a clock that is twice the bit rate of the data signal. Table 57 and Figure 43 and Figure 44 show SPDIF timing parameters for the Sony/Philips Digital Interconnect Format (SPDIF), including the timing of the modulating Rx clock (SPDIF_SR_CLK) for SPDIF in Rx mode and the timing of the modulating Tx clock (SPDIF_ST_CLK) for SPDIF in Tx mode.

Each USBx_VBUS pin must be isolated by an external 30 K1% precision resistor. The USB 2.0 PHY uses USBx_TXRTUNE and an external resistor to calibrate the USBx_DP/DN 45 source impedance. The external resistor value is 200 1% precision on each of USBx_TXRTUNE pad to ground. 3.9.14.2 USB PHY worst power consumption Table 61 shows the USB 2.0 PHY worst power dissipation. i.MX 8M Mini Applications Processor Datasheet for Consumer Products, Rev. 1, 07/2020 66 NXP Semiconductors Mode HS TX FS TX LS TX Suspend Sleep Electrical characteristics Table 61.
