AT52BC6402A(T)
The device is a 16-Mbit 1T/1C PSRAM featured by high-speed operation and super low
power consumption. The 16-Mbit device adopts one transistor memory cell and is orga-
nized as 1,048,576 words by 16 bits. It operates in the extended range of temperatures
and supports a wide operating voltage range. The device also supports the deep power-
down mode for a super low standby current.
