Cypress CY62147EV30 Automotive 4-mbit (256k x 16) static ram wide voltage range: 2.20 v to 3.60 v Datasheet

CY62147EV30 MoBL®
Automotive 4-Mbit (256K x 16) Static RAM
Features
also has an automatic power down feature that significantly
reduces power consumption when addresses are not toggling.
Placing the device into standby mode reduces power
consumption by more than 99 percent when deselected (CE
HIGH or both BLE and BHE are HIGH). The input and output pins
(I/O0 through I/O15) are placed in a high impedance state when:
Very high speed: 45 ns
Temperature ranges
❐ Automotive-A: –40 °C to +85 °C
❐ Automotive-E: –40 °C to +125 °C
■ Wide voltage range: 2.20 V to 3.60 V
■ Pin compatible with CY62147DV30
■ Ultra low standby power
❐ Typical standby current: 1 A
❐ Maximum standby current: 7 A (Automotive-A)
■ Ultra low active power
❐ Typical active current: 2 mA (Automotive-A) at f = 1 MHz
[1] and OE features
■ Easy memory expansion with CE
■
■
■
Automatic power down when deselected
■
Complementary metal oxide semiconductor (CMOS) for
optimum speed and power
■
Available in Pb-free 48-ball very fine ball grid array (VFBGA)
(single/dual CE option) and 44-pin thin small outline package
(TSOP) II packages
■
Byte power-down feature
■
Deselected (CE HIGH)
■
Outputs are disabled (OE HIGH)
■
Both Byte High Enable and Byte Low Enable are disabled
(BHE, BLE HIGH)
■
Write operation is active (CE LOW and WE LOW)
To write to the device, take 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 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 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 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. See the Truth Table on page 10 for a
complete description of read and write modes.
For best practice recommendations, refer to the Cypress
application note AN1064, SRAM System Guidelines.

5. VIL(min) = –2.0 V for pulse durations less than 20 ns.
6. VIH(max) = VCC + 0.75 V for pulse durations less than 20 ns.
7. Full device AC operation assumes a minimum of 100 s ramp time from 0 to VCC(min) and 200 s wait time after VCC stabilization.
8. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ), TA = 25 °C.
9. Chip enable (CE) and byte enables (BHE and BLE) need to be tied to CMOS levels to meet the ISB2 / ICCDR spec. Other inputs can be left floating.
10. Tested initially and after any design or process changes that may affect these parameters.

15. BGA packaged device is offered in single CE and dual CE options. In this data sheet, for a dual CE device, CE refers to the internal logical combination of CE1 and

16. BHE.BLE is the AND of both BHE and BLE. Deselect the chip by either disabling the chip enable signals or by disabling both BHE and BLE.

17. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (1V/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 as shown in the AC Test Load and Waveforms on page 5.
18. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification.
19. At any 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 device.
20. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
21. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE, or both = 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 setup and hold timing must be referenced to the edge of the signal that terminates the write.

Notes
34. BGA packaged device is offered in single CE and dual CE options. In this data sheet, for a dual CE device, CE refers to the internal logical combination of CE1 and
CE2 such that when CE1 is LOW and CE2 is HIGH, CE is LOW. For all other cases CE is HIGH.
35. For the Dual Chip Enable device, CE refers to the internal logical combination of CE1 and CE2 such that when CE1 is LOW and CE2 is HIGH, CE is LOW. For all
other cases CE is HIGH. Intermediate voltage levels is not permitted on any of the Chip Enable pins (CE for the Single Chip Enable device; CE1 and CE2 for the Dual
Chip Enable device).
