System Design Information
The following pins must be left unconnected (floating):
The following pins must be connected to GND:
For other directions on reserved or no-connects pins see
20.6
The MPC8640 requires weak pull-up resistors (2–10 kΩ 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
LSSD_MODE, TEST_MODE[0:3].The following pins require weak pull-up resistors
specific power supplies
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-
SD2_IMP_CAL_TX. The following pins should be pulled to ground with a 200-
TSECn_TX_EN signals require an external 4.7-k
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.

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 SENSEV
package for the dual core device, but not on the single core package. A solder ball is present for

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.
