4-Mbit (256K words
× 16 bit) Static RAM
Data writes are performed by asserting the Chip Enable (CE) and
Write Enable (WE) inputs LOW, while providing the data on I/O0
through I/O15 and address on A0 through A17 pins. The Byte High
Enable (BHE) and Byte Low Enable (BLE) inputs control write
operations to the upper and lower bytes of the specified memory
location. BHE controls I/O8 through I/O15 and BLE controls I/O0
through I/O7.
Features
■ High speed
❐ tAA = 10 ns / 15 ns
■ Low active and standby currents
❐ Active current: ICC = 38-mA typical
❐ Standby current: ISB2 = 6-mA typical
Data reads are performed by asserting the Chip Enable (CE) and
■ Operating voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, and
4.5 V to 5.5 V
Output Enable (OE) inputs LOW and providing the required
address on the address lines. Read data is accessible on the I/O
lines (I/O0 through I/O15). Byte accesses can be performed by
asserting the required byte enable signal (BHE or BLE) to read
either the upper byte or the lower byte of data from the specified
address location.
■ 1.0-V data retention
■ TTL-compatible inputs and outputs
■ Pb-free 44-pin SOJ, 44-pin TSOP II, and 48-ball VFBGA
packages
All I/Os (I/O0 through I/O15) are placed in a high-impedance state
during the following events:
Functional Description
■ The device is deselected (CE HIGH)
CY7C1041GN is high-performance CMOS fast static RAM
Organized as 256K words by 16-bits.
■ The control signals (OE, BLE, BHE) are de-asserted
