Temperature ranges
❐ Automotive-E: –40 °C to 125 °C
The CY7C1041CV33 Automotive is a high performance
complementary metal oxide semiconductor (CMOS) static RAM
organized as 262,144 words by 16 bits. This device has an
automatic power down feature that significantly reduces power
consumption when deselected.
■
High speed
❐ tAA = 10 ns
■
Low active power
❐ 468 mW (max)
■
2.0 V data retention
■
Automatic power down when deselected
■
Independent control of upper and lower bits
■
Easy memory expansion with Chip Enable (CE) and Output
Enable (OE) features
■
Available in Pb-free 48-ball grid array (BGA) package
To write to the device, take CE and Write Enable (WE) inputs
LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins
(I/O0 through I/O7), is written into the location specified on the
address pins (A0 through A17). If Byte High Enable (BHE) is
LOW, then data from I/O pins (I/O8 through I/O15) is written into
the location specified on the address pins (A0 through A17).
To read from the device, take CE and OE LOW while forcing the
Write Enable (WE) HIGH. If BLE is LOW, then data from the
memory location specified by the address pins appear on I/O0 to
I/O7. If Byte High Enable (BHE) is LOW, then data from memory
appears on I/O8 to I/O15. For more information, see the Truth
Table on page 10 for a complete description of Read and Write
modes.
The input and output pins (I/O0 through I/O15) are placed in a
high impedance state when the device is deselected (CE HIGH),
the outputs are disabled (OE HIGH), the BHE and BLE are
disabled (BHE, BLE HIGH), or during a write operation (CE LOW
and WE LOW).

Notes
5. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, and input pulse levels of 0 to 3.0 V.
6. tPOWER gives the minimum amount of time that the power supply is at typical VCC values until the first memory access is 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, tHZBE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (c) of Figure 2 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, WE LOW, and BHE/BLE LOW. CE, WE, and BHE/BLE must be LOW to initiate a write.
The transition of these signals terminate the write. The input data setup and hold timing is referenced to the leading edge of the signal that terminates the write.
10. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
