CY7C1447AV25  
36-Mbit (1M x 36/2M x 18/512K x 72)  
Flow-Through SRAM  
Features  
Functional Description[1]  
• Supports 133-MHz bus operations  
• 1M x 36/2M x 18/512K x 72 common I/O  
• 2.5V core power supply  
The CY7C1441AV25/CY7C1443AV25/CY7C1447AV25 are 2.5V,  
1M x 36/2M x 18/512K x 72 Synchronous Flow-through  
SRAMs, respectively 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 incre-  
ments 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,  
• 2.5V/1.8V I/O power supply  
• Fast clock-to-output times  
— 6.5 ns (133-MHz version)  
• Provide high-performance 2-1-1-1 access rate  
• User-selectable burst counter supporting Intel®  
Pentium® interleaved or linear burst sequences  
and ADV), Write Enables (BWx, and BWE), and Global Write  
(GW). Asynchronous inputs include the Output Enable (OE)  
and the ZZ pin.  
• Separate processor and controller address strobes  
• Synchronous self-timed write  
• Asynchronous output enable  
The CY7C1441AV25/CY7C1443AV25/CY7C1447AV25 allows  
either interleaved or linear burst sequences, selected by the  
MODE input pin. A HIGH selects an interleaved burst  
sequence, while 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.  
• CY7C1441AV25, CY7C1443AV25 available in lead-free  
100-pin TQFP package, lead-free and non-lead-free  
165-ball FBGA package. CY7C1447AV25 available in  
lead-free and non-lead-free 209-ball FBGA package  
• JTAG boundary scan for FBGA package  
• “ZZ” Sleep Mode option  
Addresses and chip enables are registered at rising edge of  
clock when either Address Strobe Processor (ADSP) or  
Address Strobe Controller (ADSC) are active. Subsequent  
burst addresses can be internally generated as controlled by  
the Advance pin (ADV).  
The CY7C1441AV25/CY7C1443AV25/CY7C1447AV25  
operates from a +2.5V core power supply while all outputs may  
operate with either a +2.5V or 1.8V supply. All inputs and  
outputs are JEDEC-standard JESD8-5-compatible.
