CY7C1381D CY7C1383D CY7C1383F 18-Mbit (512K 36/1M 18) Flow-Through SRAM 18-Mbit (512K 36/1M 18) Flow-Through SRAM Features Functional Description Supports 133 MHz bus operations The CY7C1381D/CY7C1383D/CY7C1383F is a 3.3 V, 512K 36 and 1M 18 synchronous flow through SRAMs, 512K 36 and 1M 18 common I/O designed to interface with high speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 3.3 V core power supply (V ) DD 6.5 ns (133 MHz version). A 2-bit on-chip counter captures the first address in a burst and increments the address automatically 2.5 V or 3.3 V I/O supply (V ) DDQ for the rest of the burst access. All synchronous inputs are gated Fast clock-to-output time by registers controlled by a positive edge triggered clock input (CLK). The synchronous inputs include all addresses, all data 6.5 ns (133 MHz version) inputs, address pipelining chip enable (CE ), depth-expansion 1 Provides high performance 2-1-1-1 access rate chip enables (CE and CE ), burst control inputs (ADSC, ADSP, 2 3 and ADV), write enables (BW , and BWE), and global write x User selectable burst counter supporting Intel Pentium (GW). Asynchronous inputs include the output enable (OE) and interleaved or linear burst sequences the ZZ pin. Separate processor and controller address strobes The CY7C1381D/CY7C1383D/CY7C1383F allows interleaved or linear burst sequences, selected by the MODE input pin. A Synchronous self-timed write HIGH selects an interleaved burst sequence, while a LOW Asynchronous output enable selects a linear burst sequence. Burst accesses can be initiated with the processor address strobe (ADSP) or the cache CY7C1381D available in JEDEC-standard Pb-free 100-pin controller address strobe (ADSC) inputs. Address advancement TQFP, Pb-free and non Pb-free 165-ball FBGA package. is controlled by the address advancement (ADV) input. CY7C1383D available in JEDEC-standard Pb-free 100-pin Addresses and chip enables are registered at rising edge of TQFP. CY7C1383F available in non Pb-free 165-ball FBGA clock when address strobe processor (ADSP) or address strobe package. controller (ADSC) are active. Subsequent burst addresses can be internally generated as controlled by the advance pin (ADV). IEEE 1149.1 JTAG-Compatible Boundary Scan CY7C1381D/CY7C1383D/CY7C1383F operates from a +3.3 V ZZ sleep mode option core power supply while all outputs operate with a +2.5 V or +3.3 V supply. All inputs and outputs are JEDEC-standard and JESD8-5-compatible. For a complete list of related documentation, click here.
