EM033C08
EM033C08
Low Power 32Kx8 SRAM in a 32 pin ROM Pinout Compatible Package
Overview
Features
The EM033C08 is an integrated memory device
containing a low power 256 Kbit Static Random
Access Memory organized as 32,768 words by 8
bits. The device is fabricated using an advanced
CMOS process and NanoAmp’s high-speed/low-
power circuit technology. This device is designed
to be quite effective in battery powered products
with it’s very low operating and standby currents. It
is also capable of full operation at voltages as low
as 1.5 volts. The device pinout is fully compatible
with NanoAmp’s EM02R2XX family of Combination
RAM and ROM products making it very easy to
substitute an SRAM only device where the ROM is
unneccessary in the application. This device is
extremely stable over broad temperature and volt-
age ranges.
