Freescale Semiconductor
Features
GPIO_NAND
This is a general-purpose input/output (GPIO3_12) on the NVCC_NANDF_A power rail.
IOB, IOG, IOR,
IOB_BACK, IOG_BACK,
and IOR_BACK
These signals are analog TV outputs that should be tied to GND when not being used.
JTAG_nnnn
The JTAG interface is summarized in Table 4. Use of external resistors is unnecessary. However,
if external resistors are used, the user must ensure that the on-chip pull-up/down configuration is
followed. For example, do not use an external pull down on an input that has on-chip pull-up.
JTAG_TDO is configured with a keeper circuit such that the floating condition is eliminated if an
external pull resistor is not present. An external pull resistor on JTAG_TDO is detrimental and
should be avoided.
JTAG_MOD is referenced as SJC_MOD in the i.MX51 Multimedia Applications Processor
Reference Manual (MCIMX51RM). Both names refer to the same signal. JTAG_MOD must be
externally connected to GND for normal operation. Termination to GND through an external
pull-down resistor (such as 1 k
Ω) is allowed.
NC
These signals are No Connect (NC) and should be floated by the user.
PMIC_INT_REQ
When using the MC13892 power management IC, the PMIC_INT_REQ high-priority interrupt input
on i.MX51 should be either floated or tied to NVCC_SRTC_POW with a 4.7 k
Ω to 68 kΩ resistor.
This avoids a continuous current drain on the real-time clock backup battery due to a 100 k
Ω
on-chip pull-up resistor.
PMIC_INT_REQ is not used by the Freescale BSP (board support package) software. The BSP
requires that the general-purpose INT output from the MC13892 be connected to the i.MX51 GPIO
input GPIO1_8 configured to cause an interrupt that is not high-priority.
The original intent was for PMIC_INT_REQ to be connected to a circuit that detects when the
battery is almost depleted. In this case, the I/O must be configured as alternate mode 0 (ALT0 =
power fail).
POR_B
This cold reset negative logic input resets all modules and logic in the IC.
Note: The POR_B input must be immediately asserted at power-up and remain asserted until
after the last power rail is at its working voltage.
RESET_IN_B
This warm reset negative logic input resets all modules and logic except for the following:
Test logic (JTAG, IOMUXC, DAP)
SRTC
Memory repair – Configuration of memory repair per fuse settings
Cold reset logic of WDOG – Some WDOG logic is only reset by POR_B. See WDOG chapter
in i.MX51 Multimedia Applications Processor Reference Manual (MCIMX51RM) for details.
RREFEXT
Determines the reference current for the USB PHY bandgap reference. An external 6.04 k
Ω 1%
resistor to GND is required.
SGND, SVCC, and
SVDDGP
These sense lines provide the ability to sense actual on-chip voltage levels on their respective
supplies. SGND monitors differentials of the on-chip ground versus an external power source.
SVCC monitors on-chip VCC, and SVDDGP monitors VDDGP. Freescale recommends
connection of the SVCC and SVDDGP signals to the feedback inputs of switching power-supplies
or to test points.
STR
This signal is reserved for Freescale manufacturing use. The user should float this signal.
TEST_MODE
TEST_MODE is for Freescale factory use only. This signal is internally connected to an on-chip
pull-down device. Users must either float this signal or tie it to GND.
