Cypress Computer Hardware CY62136VN User Manual

CY62136VN MoBL®  
2-Mbit (128K x 16) Static RAM  
portable applications such as cellular telephones. The device  
also has an automatic power-down feature that significantly  
reduces power consumption by 99% when addresses are not  
toggling. The device can also be put into standby mode when  
Features  
• Temperature Ranges  
— Industrial: –40°C to 85°C  
deselected (CE HIGH). The input/output pins (I/O through  
0
— Automotive-A: –40°C to 85°C  
— Automotive-E: –40°C to 125°C  
• High speed: 55 ns  
I/O ) are placed in a high-impedance state when: deselected  
15  
(CE HIGH), outputs are disabled (OE HIGH), BHE and BLE  
are disabled (BHE, BLE HIGH), or during a write operation (CE  
LOW, and WE LOW).  
• Wide voltage range: 2.7V–3.6V  
• Ultra-low active, standby power  
• Easy memory expansion with CE and OE features  
• TTL-compatible inputs and outputs  
• Automatic power-down when deselected  
• CMOS for optimum speed/power  
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/O through I/O ), is  
0
7
written into the location specified on the address pins (A  
0
through A ). If Byte High Enable (BHE) is LOW, then data  
16  
from I/O pins (I/O through I/O ) is written into the location  
8
15  
specified on the address pins (A through A ).

16  
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  
• Available in standard Pb-free 44-pin TSOP Type II,  
Pb-free and non Pb-free 48-ball FBGA packages  
Functional Description[1]  
pins will appear on I/O to I/O . If Byte High Enable (BHE) is  
0

LOW, then data from memory will appear on I/O to I/O . See  
the Truth Table at the back of this data sheet for a complete  
description of read and write modes.

12. The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can  
terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.  
13. The minimum write cycle time for write cycle 3 (WE controlled, OE LOW) is the sum of t
