The MCM can be organized as a 128K x 32 bits, 256K x 16 bits or 512k x 8 bits device and is input and output TTL compatible. Writing is executed when the write enable (WE) and chip enable (CE) inputs are low. Reading is accomplished when WE is high and CE and output enable (OE) are both low. Access time grades of 17ns, 20ns, 25ns, 35ns, 45ns and 55ns maximum are standard. The products are designed for operation over the temperature range of -55°C to +125°C and screened under the full military environment. DESC Standard Military Drawing (SMD) part numbers are pending. The ACT-S128K32V is manufactured in Aeroflex’s 80,000ft2 MIL-PRF-38534 certified facility in Plainview, N.Y. eroflex Circuit Technology - Advanced Multichip Modules © SCD3359 REV B 12/17/98 Absolute Maximum Ratings Symbol TC TSTG PD Rating Range Units Case Operating Temperature -55 to +125 °C Storage Temperature -65 to +150 °C P7 Packages 3.0 W F2 Package 2.7 W P7 Packages 3.0 °C/W F2 Package 9.0 °C/W -0.5 to +4.6 V 300 °C Maximum Package Power Dissipation ØJ-C Hottest Die, Max Thermal Resistance - Junction to Case VG Maximum Signal Voltage to Ground TL Maximum Lead Temperature (10 seconds) Normal Operating Conditions Symbol Parameter Minimum Maximum Units VCC Power Supply Voltage +3.0 +3.6 V VIH Input High Voltage +2.0 VCC + 0.3 V VIL Input Low Voltage -0.3 +0.8 V Truth Table Mode Standby Read Read Write CE H L L L OE X L H X WE X H H L Data I/O High Z Data Out High Z Data In Power Standby (deselect/power down) Active Active (deselected) Active Capacitance (f = 1MHz, TC = 25°C) Symbol Parameter Maximum Units CAD A0 – A16 Capacitance 50 pF COE OE Capacitance 50 pF CWE Write Enable Capacitance 20 pF CCE Chip Enable Capacitance 20 pF CI/O I/O0 – I/O31 Capacitance 20 pF Capacitance is guaranteed by design but not tested.
