Freescale Semiconductor
System Design Information
The following pins must be left unconnected (floating):
SDn_TX[7:0]
The following pins must be connected to GND:
SDn_RX[7:0]
SDn_REF_CLK
SDn_REF_CLK
NOTE
It is recommended to power down the unused lane through SRDS1CR1[0:7]
register (offset = 0xE_0F08) and SRDS2CR1[0:7] register
(offset = 0xE_0F44.) (This prevents the oscillations and holds the receiver
output in a fixed state.) that maps to SERDES lane 0 to lane 7 accordingly.
For other directions on reserved or no-connects pins see Section 17, “Signal Listings.”

Pull-Up and Pull-Down Resistor Requirements
The MPC8640 requires weak pull-up resistors (2–10 k
Ω is recommended) on all open drain type pins.
The following pins must not be pulled down during power-on reset: TSEC4_TXD[4], LGPL0/LSDA10,
LGPL1/LSDWE, TRIG_OUT/READY, and D1_MSRCID[2].
The following are factory test pins and require strong pull-up resistors
(100
Ω –1 kΩ) to OV
DD
LSSD_MODE, TEST_MODE[0:3].The following pins require weak pull-up resistors
(2–10 k
Ω) to their
specific power supplies: LCS[0:4], LCS[5]/DMA_DREQ2, LCS[6]/DMA_DACK[2],
LCS[7]/DMA_DDONE[2], IRQ_OUT, IIC1_SDA, IIC1_SCL, IIC2_SDA, IIC2_SCL, and
CKSTP_OUT.
The following pins should be pulled to ground with a 100-
Ω resistor: SD1_IMP_CAL_TX,
SD2_IMP_CAL_TX. The following pins should be pulled to ground with a 200-
Ω resistor:
SD1_IMP_CAL_RX, SD2_IMP_CAL_RX
TSECn_TX_EN signals require an external 4.7-k
Ω pull down resistor to prevent PHY from seeing a valid
Transmit Enable before it is actively driven.
When the platform frequency is 400 MHz, TSEC1_TXD[1] must be pulled down at reset.
TSEC2_TXD[4] and TSEC2_TX_ER pins function as cfg_dram_type[0 or 1] at reset and MUST BE
VALID BEFORE HRESET ASSERTION when coming out of device sleep mode.

Special instructions for Single Core device
The mechanical drawing for the single core device does not have all the solder balls that exist on the single
core device. This includes all the balls for VDD_Core1 and SENSEVDD_Core1 which exist on the
package for the dual core device, but not on the single core package. A solder ball is present for
