Features
Functional Description
The CY7C1041B is a high-performance CMOS static RAM
organized as 262,144 words by 16 bits.
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
• High speed
• Low active power
• Low CMOS standby power (L version)
• 2.0V Data Retention (400 µW at 2.0V retention)
• Automatic power-down when deselected
• TTL-compatible inputs and outputs
• Easy memory expansion with CE and OE features

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,

The CY7C1041B 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.
