Manufacturer:AVX Description: For serial programming, SEN together with LD on each rising edge of WCLK, are used to load the offset registers via the Serial Input (SI). For parallel programming, WEN together with LD on each rising edge of WCLK, are used to load the offset registers via Dn. REN together with LD on each rising edge of RCLK can be used to read the offsets in parallel from Qn regardless of whether serial or parallel offset loading has been selected. During Master Reset (MRS) the following events occur: The read and write pointers are set to the first location of the FIFO. The FWFT pin selects IDT Standard mode or FWFT mode. The LD pin selects either a partial flag default setting of 127 with parallel programming or a partial flag default setting of 1,023 with serial programming. The flags are updated according to the timing mode and default offsets selected. The Partial Reset (PRS) also sets the read and write pointers to the first location of the memory. However, the timing mode, partial flag programming method, and default or programmed offset settings existing before Partial Reset remain unchanged. The flags are updated according to the timing mode and offsets in effect. PRS is useful for resetting a device in mid-operation, when reprogramming partial flags would be undesirable. The Retransmit function allows data to be reread from the FIFO more than once. A LOW on the RT input during a rising RCLK edge initiates a retransmit operation by setting the read pointer to the first location of the memory array. If, at any time, the FIFO is not actively performing an operation, the chip will automatically power down. Once in the power down state, the standby supply current consumption is minimized. Initiating any operation (by activating control inputs) will immediately take the device out of the power down state. The IDT72V255LA/72V265LA are fabricated using IDTs high speed submicron CMOS technology. |
