CY7C1046D Datasheet | Cypress

4-Mbit (1 M × 4) Static RAM 4-Mbit (1 M × 4) Static RAM Features - Pin- and function-patible with CY7C1046B - High speed - t AA = 10 ns - CMOS for optimum speed and power - Low active power - ICC = 90 m A at 10 ns - Low CMOS standby power - ISB2 = 10 m A - Data retention at 2.0 V - Automatic power-down when deselected - TTL-patible 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 acplished 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...
