CY7C1447AV25 available in non Pb-free 209-ball FBGA package. ■ JTAG boundary scan for FBGA package ■ ZZ sleep mode option Functional Description The CY7C1441AV25/CY7C1447AV25 are 2.5 V, 1 M × 36/512 K × 72 Synchronous Flow-Through SRAMs, designed to interface with high speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 6.5 ns (133 MHz version). A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access. All synchronous inputs are gated by registers controlled by a positive edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address pipelining Chip Enable (CE1), depth expansion Chip Enables (CE2 and CE3), Burst Control inputs (ADSC, ADSP, and ADV), Write Enables (BWx and BWE), and Global Write (GW). Asynchronous inputs include the Output Enable (OE) and the ZZ pin. The CY7C1441AV25/CY7C1447AV25 allows either interleaved or linear burst sequences, selected by the MODE input pin. A HIGH selects an interleaved burst sequence and a LOW selects a linear burst sequence. Burst accesses can be initiated with the Processor Address Strobe (ADSP) or the cache Controller Address Strobe (ADSC) inputs. Address advancement is controlled by the Address Advancement (ADV) input. Addresses and chip enables are registered at rising edge of clock when either ADSP or ADSC are active. Subsequent burst addresses can be internally generated as controlled by the ADV. The CY7C1441AV25/CY7C1447AV25 operates from a +2.5 V core power supply while all outputs may operate with either a +2.5 V or 1.8 V supply. All inputs and outputs are JEDEC-standard JESD8-5 compatible.
