PIN DESIGNATIONS  
Pin Naming  
This section identifies the pins of the ÉlanSC400 and  
ÉlanSC410 microcontrollers and lists the signals asso-  
ciated with each pin.  
The Signal Name column in the Pin Designation tables  
beginning on page 26 and in the Pin State tables be-  
ginning on page 40 is decoded as follows:  
Several different tables are included in this section.  
NAME1/NAME2 {NAME3} [NAME4] [[NAME5]]  
The Pin Designations (Pin Number)—ÉlanSC400  
Microcontroller table beginning on page 26 lists the  
ÉlanSC400 microcontroller signals sorted by pin  
number.  
NAME1  
This is the only function for the pin.  
NAME1/NAME2  
The slash separates two functions that are available on  
the pin at the same time (i.e., at different times in the  
same design the pin is used for different functions).  
The Pin Designations (Pin Number)—ÉlanSC410  
Microcontroller table on page 33 lists the  
ÉlanSC410 microcontroller signals sorted by pin  
number.  
{NAME3}  
The name in braces is the pin function during a hard-  
ware reset.  
Along with the Connection Diagram on page 24,  
these tables can be used to associate the complete  
pin name (including all multiplexed functions) with  
the physical pin on the BGA package.  
[NAME4]  
The name in square brackets is the alternative function  
for the pin, selected by firmware configuration. Only  
one function is available for each configuration.  
The Pin Designations (Pin Name)—ÉlanSC400  
Microcontroller table on page 29 lists the  
ÉlanSC400 microcontroller signals sorted in  
alphabetical order.  
[[NAME5]]  
The name inside double square brackets is the  
alternate function for the pin, selected by a hardware  
configuration pin state at power-on reset. This does not  
apply to [[BNDSCN_TCK]], [[BNDSCN_TMS]],  
[[BNDSCN_TDI]], and [[BNDSCN_TDO]]. These four  
alternate functions are enabled by the BNDSCN_EN  
signal. Only one function is available for each  
configuration.  
The Pin Designations (Pin Name)—ÉlanSC410  
Microcontroller table on page 36 lists the  
ÉlanSC410 microcontroller signals sorted in  
alphabetical order.  
All multiplexed signals are included in these lists.  
Note that these tables should not be used to  
determine primary and secondary functions for  
multiplexed pins because the ordering was  
changed to alphabetize every function. Please refer  
to the Pin Designations (Pin Number) table or the  
Pin State tables for the definitive listing of primary  
and secondary functions in the correct order for  
each pin.  
PIN CHANGES FOR THE ÉlanSC410  
MICROCONTROLLER  
The following signals supported on the ÉlanSC400  
microcontroller are not available on the ÉlanSC410  
microcontroller.  
Configuration signal: CFG2  
The Pin State tables beginning on page 42, which  
group pins alphabetically by function, show pin  
states during reset, normal operation, and Suspend  
mode, along with output drive strength, maximum  
load, supply source, and power-down groups.  
PC Card controller signals: MCEL_A, MCEL_B,  
MCEH_A, MCEH_B, RST_A, RST_B, REG_A,  
REG_B, CD_A, CD_B, CD_A2, RDY_A, RDY_B,  
BVD1_A, BVD1_B, BVD2_A, BVD2_B, WP_A,  
WP_B, WAIT_AB, OE, WE, ICDIR, PCMA_VCC,  
PCMA_VPP1, PCMA_VPP2, PCMB_VCC,  
PCMB_VPP1, PCMB_VPP2  
The Signal Description table beginning on page 62  
includes complete pin descriptions in alphabetical  
order by function.  
Graphics controller signals: LCDD7–LCDD0, M,  
The table beginning on page 70 clarifies the  
configuration options for those pins having multiple  
functions.  
LC, SCK, FRM, LVEE, LVDD  
Loop filter signal: LF_VID
