Features • Operating Voltage: 3.3V • Access Time: – 15 ns • Very Low Power Consumption • • • • • • • • • – Active: 650 mW (Max) @ 15 ns, 540 mW (Max) @ 25 ns – Standby: 3.3 mW (Typ) Wide Temperature Range: -55 to +125°C TTL-Compatible Inputs and Outputs Asynchronous Designed on 0.25 µm Radiation Hardened Process No Single Event Latch Up below LET Threshold of 80 MeV/mg/cm2@125°C Tested up to a Total Dose of 300 krads (Si) according to MIL-STD-883 Method 1019 500 Mils Wide FP36 Package ESD better than 4000V Quality Grades: – QML-Q or V – ESCC Rad Hard 512K x 8 Very Low Power CMOS SRAM AT60142H Description The AT60142H is a very low power CMOS static RAM organized as 524 288 x 8 bits. 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 AT60142H combines an extremely low standby supply current (Typical value = 1 mA) with a fast access time at 15 ns or better over the full military temperature range. The high stability of the 6T cell provides excellent protection against soft errors due to noise. The AT60142H 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 µm CMOS process. 7834A–AERO–10/09 1 AT60142H 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).
