CY7C1046D 4-Mbit (1 M × 4) Static RAM 4-Mbit (1 M × 4) Static RAM Features ■ Pin- and function-compatible with CY7C1046B ■ High speed ❐ tAA = 10 ns ■ CMOS for optimum speed and power ■ Low active power ❐ ICC = 90 mA at 10 ns ■ Low CMOS standby power ❐ ISB2 = 10 mA ■ Data retention at 2.0 V ■ Automatic power-down when deselected ■ TTL-compatible inputs and outputs ■ Easy memory expansion with CE and OE features ■ Available in lead-free 400-mil-wide 32-pin SOJ package Functional Description The CY7C1046D is a high-performance CMOS static RAM organized as 1M words by 4 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and tri-state drivers. Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the four I/O pins (I/O0 through I/O3) is then written into the location specified on the address pins (A0 through A19). Reading from the device is accomplishe...
