(15 mA) • Low standby power (55/70 ns Commercial, Industrial, Automotive-A) — 110 µW (max.) (15 µA) • Automatic power-down when deselected • TTL-compatible inputs and outputs • Easy memory expansion with CE1, CE2, and OE options • Available in Pb-free and non-Pb-free 32-pin (450 mil-wide) SOIC, 32-pin STSOP and 32-pin TSOP-I Functional Description[1] The CY62128BN is a high-performance CMOS static RAM organized as 128K words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE1), an active HIGH Chip Enable (CE2), an active LOW Output Enable (OE), and tri-state drivers. This device has an automatic power-down feature that reduces power consumption by more than 75% when deselected. Writing to the device is accomplished by taking Chip Enable One (CE1) and Write Enable (WE) inputs LOW and Chip Enable Two (CE2) input HIGH. 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). Reading from the device is accomplished by taking Chip Enable One (CE1) and Output Enable (OE) LOW while forcing Write Enable (WE) and Chip Enable Two (CE2) 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 (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or during a write operation (CE1 LOW, CE2 HIGH, and WE LOW).

Test conditions assume signal transition time of 5 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 100-pF load capacitance. 8. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage. 9. 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. 10. The internal write time of the memory is defined by the overlap of CE1 LOW, CE2 HIGH, and WE LOW. CE1 and WE must be LOW and CE2 HIGH 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. 11. Device is continuously selected. OE, CE1 = VIL, CE2 = VIH. 12. WE is HIGH for read cycle.
