CY62177DV30
MoBL®
32-Mbit (2M x 16) Static RAM
Features
reduces power consumption. The device can also be put into
standby mode when deselected (CE1 HIGH or CE2 LOW or
both BHE and BLE are HIGH). The input/output pins (I/O0
through I/O15) are placed in a high-impedance state when:
deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE
HIGH), both Byte High Enable and Byte Low Enable are
disabled (BHE, BLE HIGH), or during a write operation (CE1
LOW, CE2 HIGH and WE LOW).
• Very high speed: 55 ns and 70 ns
• Wide voltage range: 2.20V–3.60V
• Ultra-low active power
— Typical active current: 2 mA @ f = 1 MHz
— Typical active current: 15 mA @ f = fmax
Writing to the device is accomplished by taking Chip Enables
(CE1 LOW and CE2 HIGH) and Write Enable (WE) input 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 A20). 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 A20).
• Ultra low standby power
• Easy memory expansion with CE1, CE2 and OE features
• Automatic power-down when deselected
• CMOS for optimum speed/power
• Packages offered in a 48-ball FBGA
Reading from the device is accomplished by taking Chip
Enables (CE1 LOW and CE2 HIGH) and Output Enable (OE)
LOW while forcing the Write Enable (WE) HIGH. If Byte Low
Enable (BLE) is LOW, then data from the memory location
specified by the address pins will appear on I/O0 to I/O7. If Byte
High Enable (BHE) is LOW, then data from memory will appear
on I/O8 to I/O15. See the truth table for a complete description
of read and write modes.
Functional Description[1]

Notes:
10. BHE.BLE is the AND of both BHE and BLE. Chip can be deselected by either disabling the chip enable signals or by disabling both BHE and BLE.
11. CE is the logical combination of CE1 and CE2. When CE1 is LOW and CE2 is HIGH, CE is LOW; when CE1 is HIGH or CE2 is LOW, CE is HIGH.
12. Test conditions for all parameters other than tri-state parameters assume signal transition time of 1 ns/V, timing reference levels of VCC(typ)/2, input pulse levels
of 0 to VCC(typ.), and output loading of the specified IOL/IOH as shown in the “AC Test Loads and Waveforms” section.
13. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any
given device.
14. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
15. The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any
of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates
the write.
