VSSQ 5,10,21,26, 55,60,71,76 - - I/O Ground Ground for the I/O circuitry. VDDQ 4,11,20,27, 54,61,70,77 A1,A7,F1, F7,J1,J7, M1,M7,U1, U7 C3,C9,D3,D9 ,E3,E9,F3,F9 ,G3,G9,J3,J9 ,K3,K9,L3,L9 ,M3,M9,N3, N9 I/O Power Sup- ply 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 out- put 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 left unconnected. 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 uti- lized, this pin can be left floating or connected to VDD through a pull up resistor. 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 uti- lized, this pin can be disconnected 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. NC 1,2,3,6,7,14, 16,25,28,29, 30,38,39,51, 52,53,56,57, 66,75,78,79, 95,96 B1,B7,C1, C7,D2,D4, D7,E1,E6, H2,F2,G1, G6,H7,J3, J5,K1,K6, L4,L2,L7, M6,N2,L7, P1,P6,R1, R5,R7,T1, T4,U6 A5,B1,B4,C1 ,C2,C10,D1, D10,E1,E10, F1,F10,G1, G10,H1,H3, H9,H10,J2, J11,K2,K11, L2,L1,M2, M11,N2,N10, N5,N7,N11, P1,A1,B11, P2,R2 - No Connects. Not internally connected to the die. CY7C1387CV25:Pin Definitions (continued) Name TQFP BGA (2-Chip Enable) fBGA I/O Description |
