Cypress CY62137CV33LL-70BVI 2m (128k x 16) static ram Datasheet

CY62137CV25/30/33 MoBL®
CY62137CV MoBL®
2M (128K x 16) Static RAM
Life™ (MoBL®) in portable applications such as cellular
telephones. The devices also has an automatic power-down
feature that significantly reduces power consumption by 80%
when addresses are not toggling. The device can also be put
into standby mode reducing power consumption by more than
99% when deselected (CE HIGH or both BLE and BHE are
HIGH). The input/output pins (I/O0 through I/O15) are placed
in a high-impedance state when: deselected (CE HIGH),
outputs are disabled (OE HIGH), both Byte High Enable and
Byte Low Enable are disabled (BHE, BLE HIGH), or during a
write operation (CE LOW, and WE LOW).
Features
• Very high speed: 55 ns and 70 ns
• Temperature Ranges
— Industrial: –40°C to +85°C
— Automotive: –40°C to +125°C
• Pin-compatible with the CY62137V
• Ultra-low active power
— Typical active current: 1.5 mA @ f = 1 MHz
Writing to the device is accomplished by taking Chip Enable
(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 A16). 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 A16).
— Typical active current: 5.5 mA @ f = fmax (70-ns
speed)
• Low and ultra-low standby power
• Easy memory expansion with CE and OE features
• Automatic power-down when deselected
• CMOS for optimum speed/power
• Offered in a lead-free and non-lead-free 48-ball FBGA
packages
Functional Description[1]
The CY62137CV25/30/33 and CY62137CV are high-performance CMOS static RAMs organized as 128K words by 16
bits. These devices feature advanced circuit design to provide
ultra-low active current. This is ideal for providing More Battery
Reading from the device is accomplished by taking Chip
Enable (CE) 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 at the back of this data sheet for a complete
description of read and write modes.

7. Full-device AC operation requires linear VCC ramp from VDR to VCC(min.) > 100 µs or stable at VCC(min.) > 100 µs.
8. 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.

Notes:
9. Test conditions assume signal transition time of 5 ns or less, timing reference levels of VCC(typ.)/2, input pulse levels of 0 to VCC(typ.), and output loading of the
specified IOL/IOH and 30-pF load capacitance.
10. 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.
11. If both byte enables are toggled together this value is 10 ns.
12. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
13. 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.
