8 / 33 page CY7C1380D, CY7C1382D CY7C1380F, CY7C1382F Document Number: 38-05543 Rev. *I Page 8 of 33 VDDQ I/O Power Supply Power supply for the I/O circuitry. MODE 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 must remain static during device operation. Mode pin has an internal pull up. TDO 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 must be disconnected. This pin is not available on TQFP packages. TDI 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 disconnected or connected to VDD. This pin is not available on TQFP packages. TMS 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 disconnected or connected to VDD. This pin is not available on TQFP packages. TCK 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 – No Connects. 36M, 72M, 144M, 288M, 576M, and 1G are address expansion pins and are not internally connected to the die. Table 1.
