CY7C1019B 128K x 8 Static RAM Features expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and tri-state drivers. This device has an automatic power-down feature that significantly reduces power consumption when deselected. • High speed — tAA = 12 ns Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A16). • CMOS for optimum speed/power • Center power/ground pinout • Automatic power-down when deselected • Easy memory expansion with CE and OE options • Functionally equivalent to CY7C1019 • Available in Pb-free and non Pb-free 32-pin TSOP II, non Pb-free 400-mil-wide SOJ packages. Functional Description The CY7C1019B is a high-performance CMOS static RAM organized as 131,072 words by 8 bits. Easy memory Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins. The eight input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE LOW, and WE LOW).

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified IOL/IOH and 30-pF load capacitance. 5. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage. 6. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 7. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. CE and WE must be LOW to initiate a write, and the transition of any of these signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write. 8. The minimum write cycle time for Write Cycle no. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
