EM128U16 Family
128Kx16 bit Ultra-Low Power Asynchronous Static RAM
Overview
The EM128U16 is an integrated memory device
containing a low power 2 Mbit Static Random
Access Memory organized as 131,072 words by 16
bits. The design is identical to NanoAmp’s
EM128Q16 with the exception of a single Chip
Enable pin for compatibility with certain competitor
devices and low operating voltage. The device is
fabricated using NanoAmp’s advanced CMOS pro-
cess and high-speed/ultra low-power/low-voltage
circuit technology.
These designs are unique in their combination of
fast access time and very low power making them
very suitable for high performance battery powered
applications such as cellular phones and hand held
GPS navigation devices.
