Features : Description :
Low-power consumption.
-active: 30mA Icc at 55ns.
-stand by : 10 µA (CMOS input / output , LL) 2 µA (CMOS input / output, SL)
Single +2.7V to 3.6V power supply. Equal access and cycle time. 55\70\85 ns access time. Tri-state output. Automatic power-down when
deselected.
Multiple center power and ground pins
for improved noise immunity.
Individual byte controls for both read
and write cycles.
Industrial grade (-40°C ~ 85°C)
available.
Available in 48-fpBGA/44L TSOPII.
The GLT6200L16 is a low power CMOS Static RAM organized as 131,072 words by 16 bits. Easy memory expansion is provided by an active LOW
CE1 and OE pin.
This device has an automatic power – down mode feature when deselected. Separate Byte
Enable controls ( BLE and BHE ) allow individual bytes to be accessed. BLE controls the lower bits I/O0 – I/O7. BHE controls the upper bits I/O8 –
I/O15.
Writing to these devices is performed by taking Chip Enable CE1 with Write Enable WE and byte
Enable ( BLE / BHE ) Low
Reading from the device is performed by taking Chip Enable CE1 with Output enable OE and byte
Enable ( BLE / BHE ) Low while Write Enable WE and CE2 are held HIGH.
