CY7C1049CV33 Automotive 4-Mbit (512 K × 8) Static RAM 4-Mbit (512 K × 8) Static RAM Features Functional Description ■ Temperature ranges ❐ Automotive -A: –40 °C to 85 °C ❐ Automotive-E: –40 °C to 125 °C The CY7C1049CV33 Automotive is a high performance CMOS Static RAM organized as 524,288 words by eight bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and three-state drivers. 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 A18). ■ High speed ❐ tAA = 10 ns ■ Low active power ❐ 360 mW (max) ■ 2.0 V data 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 Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the I/O pins. The eight input and 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). The CY7C1049CV33 Automotive is available in standard 400-mil-wide 36-pin SOJ package and 44-pin TSOP II package with center power and ground (revolutionary) pinout.

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3.0 V. 6. tPOWER gives the minimum amount of time that the power supply should be at stable, typical VCC values until the first memory access can be performed. 7. At any temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any device. 8. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of Figure 3 on page 5. Transition is measured ±500 mV from steady-state voltage. 9. 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 either of these signals can terminate the Write. The input data setup and hold timing should be referenced to the leading edge of the signal that terminates the Write. 10. The minimum Write cycle time for Write Cycle No. 2 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
