VDDQ 4,11,20,27,54, 61,70, 77 A1,F1,J1,M1, U1, A7,F7,J7,M7, U7 C3,C9,D3,D9, E3,E9,F3,F9,G 3, G9,J3,J9, K3,K9,L3, L9,M3,M9,N3, N9 I/O Power Supply Power supply for the I/O circuitry. MODE 31 R3 R1 Input- Static Selects Burst Order. When tied to GND selects linear burst sequence. When tied to VDD or left floating selects interleaved burst sequence. This is a strap pin and should remain static during device operation. Mode Pin has an internal pull-up. TDO - U5 P7 JTAG serial output Synchronous Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK. If the JTAG feature is not being utilized, this pin should be disconnected. This pin is not available on TQFP packages. TDI - U3 P5 JTAG serial input Synchronous Serial data-In to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is not being utilized, this pin can be discon- nected or connected to VDD. This pin is not available on TQFP packages. TMS - U2 R5 JTAG serial input Synchronous Serial data-In to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is not being utilized, this pin can be discon- nected or connected to VDD. This pin is not available on TQFP packages. TCK - U4 R7 JTAG-Clock Clock input to the JTAG circuitry. If the JTAG feature is not being utilized, this pin must be connected to VSS. This pin is not available on TQFP packages.
