Description
The AT65609EHV is a very low power CMOS static RAM organized as 131072 x 8
bits. Utilizing an array of six transistors (6T) memory cells, the AT65609EHV com-
bines an extremely low standby supply current with a fast access time at 40 ns over
the full military temperature range. The high stability of the 6T cell provides excellent
protection against soft errors due to noise.
The AT65609EHV is processed according to the methods of the latest revision of the
MIL PRF 38535 or ESCC 9000.
It is manufactured on the same process as the MH1RT RAD-hard sea of gates series.

Data Retention Mode
Atmel CMOS RAM’s are designed with battery backup in mind. Data retention voltage and sup-
ply current are guaranteed over temperature. The following rules ensure data retention:
1. During data retention chip select CS1 must be held high within VCC to VCC -0.2V or,
chip select CS2 must be held down within GND to GND +0.2V.
2. Output Enable (OE) should be held high to keep the RAM outputs high impedance, mini-
mizing power dissipation.
3. During power up and power-down transitions CS1 and OE must be kept between VCC +
0.3V and 70% of VCC, or with CS2 between GND and GND -0.3V.
4. The RAM can begin operation > TR ns after VCC reaches the minimum operation volt-
ages (4.5V).

Write Cycle 2 WE Controlled, OE Low
Write Cycle 3 CS1 or CS2 Controlled
Note: The internal write time of the memory is defined by the overlap of CS1 Low and CS2 HIGH and
WE LOW. Both signals must be actived to initiate a write and either signal can terminate a write by
going in actived. The data input setup and hold timing should be referenced to the actived edge of
the signal that terminates the write. Data out is high impedance if OE = VIH.
