11 / 70 page  i.MX28 Applications Processors Data Sheet for Consumer Products, Rev. 1 Freescale Semiconductor 11 3 Electrical Characteristics This section provides the device-level and module-level electrical characteristics for the i.MX28. 3.1 i.MX28 Device-Level Conditions This section provides the device-level electrical characteristics for the IC. 3.1.1 DC Absolute Maximum Ratings Table 7 provides the DC absolute maximum operating conditions. CAUTION • Stresses beyond those listed under Table 7 may cause permanent damage to the device. • Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. • Table 6 gives stress ratings only—functional operation of the device is not implied beyond the conditions indicated in Table 8. DCDC_BATTERY This pin is an input of i.MX28 that provides supply to the DCDC converter. It should be connected to the battery with minimal resistance. See the “Power Supply” section of the reference manual for details. XTALI XTALO These analog pins are connected to an external 24 MHz crystal circuit. This crystal provides the clock source for on-chip PLLs. RTC_XTALO RTC_XTALI These analog pins are connected to an external 32.768/32.0 kHz crystal circuit. This crystal provides clock source to the on-chip real-time counter circuits. RESETN This pin resets the chip if it is low. This pin is pulled up to VDDIO33 with an internal 10 kohm resistor. No external pull up resistors are needed. DEBUG This pin is used for JTAG interface. DEBUG=0: JTAG interface works for boundary scan. DEBUG=1: JTAG interface works for ARM debugging. TESTMODE For Freescale factory use only. Must be externally connected to GND for normal operation. Table 6. DC Absolute Maximum Ratings Parameter Symbol Min. Max. Units Battery Pin BATT, VDD4P2V –0.3 4.242 V 5-Volt Source Pin - transient, t<30ms, duty cycle <0.05% VDD5V –0.3 7.00 V 5 Volt Source Pin - static VDD5V –0.3 6.00 V PSWITCH1 —–0.3 BATT/2 V Table 5.
