• Manufacturer Part Number: tm1300
• Description: Tm-1300 Media Processor
• Manufacturer: NXP Semiconductors

Pin List
1.1
The following summarizes pinout differences between
TM1100 and TM1300:
• TM1300 uses a BGA 27x27 package and is hence
• TM1300 no longer has the MM_MATCHOUT and
• TM1300 recommends different VDDQ/VSSQ board
• We recommend 50-ohm PCB traces for all SDRAM
1.2
TM1300 implements full IEEE 1149.1 boundary scan. Any TM1300 pin designated “IN” only (from a functionality point
of view) can become an output during boundary scan.
1.3
TM1300 has a total of 169 functional pins, excluding VDDQ, VSSQ, VREF_PCI and VREF_PERIPH and digital power/
ground. TM1300 uses the types of I/O circuits shown in the table below.
For the pins with 5-V input capability, the special pins VREF_PCI or VREF_PERIPH determine 3.3- or 5-V input toler-
ance, as per the table in
