MT5C1008(LL) Rev. 1.0 7/02 Austin Semiconductor, Inc. reserves the right to change products or specifications without notice. 1 OPTIONS MARKING • Timing 30ns access -30 • Package(s) Ceramic DIP (400 mil) C No. 111 • Temperature Military (-55°C to +125°C) MIL • Options 2V data retention/very low power LL PIN ASSIGNMENT (Top View) AVAILABLE AS MILITARY SPECIFICATIONS •MIL-STD-883, para. 1.2.2 compliant 32-Pin DIP (C) GENERAL DESCRIPTION The MT5C1008 SRAM is a high-performance CMOS static RAM organized as 131, 072 words by 8 bits, offering low active power and ultra low standby and data retention current levels. Easy memory expansion is provided by an active LOW Chip Enable (CE1\), an active HIGH Chip Enable (CE2), and active Low Output Enable (OE\), and three-state drivers. Writing to the device is accomplished by taking Chip Enable One (CE1\) and Write Enable (WE\) inputs LOW and Chip Enable Two (CE2) input HIGH. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A16). Reading from the device is accomplished by taking Chip Enable One (CE 1 \) and Output Enable (OE\) LOW while forcing Write Enable (WE\) and Chip Enable Two (CE 2 ) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins. The eight input/output (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (CE1\) HIGH or CE2 LOW), the outputs are disabled (OE\ HIGH), or during a write operation (CE1\ LOW, CE2 HIGH, and WE\ LOW). 128K x 8 SRAM WITH DUAL CHIP ENABLE ULTRA LOW POWER FEATURES • High Speed: 30 ns • Low active power: 715 mW worst case • Low CMOS standby power: 3.3 mW worst case • 2.0V data retention, Ultra Low 0.3mW worst case power dissipation • Battery backup applications • Automatic power-down when deselected • TTL-compatible inputs and outputs • Easy memory expansion with CE1\, CE2, and OE\ options NC A16 A14 A12 A7 A6 A5 A4 A3 A2 A1 A0 I/O0 I/O1 I/O2 GND 32 31 30 29 28 26 27 25 24 23 22 21 20 19 18 17 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 VCC A15 CE2 WE\ A13 A8 A9 A11 OE\ A10 CE1\ I/O7 I/O6 I/O5 I/O4 I/O3 For more products and information please visit our web site at www.austinsemiconductor.com |
