Atmel brings the solution to applications where fast computing is as mandatory as low consumption, such as aerospace electronics, portable instruments, or embarked systems. Utilizing an array of six transistors (6T) memory cells, the AT60142HT combines an extremely low standby supply current (Typical value = 1 mA) with a fast access time at 15 ns over the full military temperature range. The high stability of the 6T cell provides excellent protection against soft errors due to noise. The AT60142HT is processed according to the methods of the latest revision of the MIL PRF 38535 or ESCC 9000. It is produced on a radiation hardened 0.25 m CMOS process. 7841A-AERO-10/09 1 AT60142HT Block Diagram Pin Configuration A0 A1 A2 A3 A4 CS I/O1 I/O2 Vcc GND I/O3 I/O4 WE A5 A6 A7 A8 A9 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 NC A18 A17 A16 A15 OE I/O8 I/O7 GND Vcc I/O6 I/O5 A14 A13 A12 A11 A10 NC Note: NC pins are not bonded internally.

Data retention voltage and supply current are guaranteed over temperature. The following rules insure data retention: 1. During data retention chip select CS must be held high within VCC to VCC -0.2V. 2. Output Enable (OE) should be held high to keep the RAM outputs high impedance, minimizing power dissipation. 3. During power-up and power-down transitions CS and OE must be kept between VCC + 0.3V and 70% of VCC. 4. The RAM can begin operation > tR ns after VCC reaches the minimum operation voltages (3V).

Both signals must be activated to initiate a write and either signal can terminate a write by going in active mode. The data input setup and hold timing should be referenced to the active edge of the signal that terminates the write.
