52 / 179 page  Pin Assignments 52 June 2003 − Revised October 2005 SPRS222E Table 1−6. Terminal Functions (Continued) SIGNAL TYPE† IPD/ DESCRIPTION NAME DM641 DM640 TYPE† IPD/ IPU‡ DESCRIPTION RESERVED FOR TEST RSV E2 E2 I IPD Reserved. For proper DM641/DM640 device operation, this pin at device reset must be pulled down via a 10-kΩ resistor. RSV — Y1 I/O/Z — Reserved [for DM640 Only]. For proper DM640 device operation, this pin at device reset must be pulled down via a 10-kΩ resistor. RSV H7 H7 A — Reserved. This pin must be connected directly to CVDD for proper device operation. RSV R6 R6 A — Reserved. This pin must be connected directly to DVDD for proper device operation. ADDITIONAL RESERVED FOR TEST A7 A7 I IPD A9 A9 I/O/Z IPD A10 A10 I/O/Z IPD A11 A11 I/O/Z IPD A13 A13 I/O/Z IPD Reserved (leave unconnected do not connect to power or ground) B8 B8 I/O/Z IPD Reserved (leave unconnected, do not connect to power or ground) B9 B9 I/O/Z IPD B10 B10 I/O/Z IPD B11 B11 I/O/Z IPD B12 B12 I/O/Z IPD C1 C1 I/O/Z — Pull down via a 10-kΩ resistor C7 C7 I/O/Z IPD C8 C8 I/O/Z IPD C9 C9 I/O/Z IPD C10 C10 I/O/Z IPD RSV C11 C11 I/O/Z IPD RSV C12 C12 I/O/Z IPD D7 D7 I/O/Z IPD D8 D8 I/O/Z IPD Reserved (leave unconnected do not connect to power or ground) D9 D9 I/O/Z IPD Reserved (leave unconnected, do not connect to power or ground) D10 D10 I/O/Z IPD D11 D11 I/O/Z IPD D12 D12 I/O/Z IPD E11 E11 I/O/Z IPD E12 E12 I/O/Z IPD E13 E13 I/O/Z IPD E14 E14 I IPD F1 F1 I/O/Z — G3 G3 I/O/Z — Pull down via a 10 kΩ resistor G4 G4 I/O/Z — Pull down via a 10-kΩ resistor H4 H4 I/O/Z — † I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground ‡ IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.) |
