CY7C1041CV33  
256K x 16 Static RAM  
HIGH Enable (BHE) is LOW, then data from I/O pins  
(I/O8I/O15) is written into the location specified on the  
address pins (A0A17).  
Features  
• Pin equivalent to CY7C1041BV33  
• High speed  
Reading from the device is accomplished by taking Chip  
Enable (CE) and Output Enable (OE) LOW while forcing the  
Write Enable (WE) HIGH. If Byte LOW Enable (BLE) is LOW,  
then data from the memory location specified by the address  
pins will appear on I/O0 I/O7. If Byte HIGH Enable (BHE) is  
LOW, then data from memory will appear on I/O8 to I/O15. See  
the truth table at the back of this data sheet for a complete  
description of Read and Write modes.  
— tAA = 10 ns  
• Low active power  
— 324 mW (max.)  
• 2.0V data retention  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs  
• Easy memory expansion with CE and OE features  
The input/output pins (I/O0I/O15  
)
are placed in  
a
high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE  
are disabled (BHE, BLE HIGH), or during a Write operation  
(CE LOW, and WE LOW).  
Functional Description[1]  
The CY7C1041CV33 is a high-performance CMOS Static  
RAM organized as 262,144 words by 16 bits.  
The CY7C1041CV33 is available in a standard 44-pin  
400-mil-wide body width SOJ and 44-pin TSOP II package  
with center power and ground (revolutionary) pinout, as well  
as a 48-ball fine-pitch ball grid array (FBGA) package.  
Writing to the device is accomplished by taking Chip Enable  
(CE) and Write Enable (WE) inputs LOW. If Byte LOW Enable  
(BLE) is LOW, then data from I/O pins (I/O0I/O7), is written  
into the location specified on the address pins (A0A17). If Byte
