FEATURES
* Access time: 200 ns * CMOS low power operation - 40 mW (typical) operating - 90 W (typical) standby * TTL compatible interface levels * Single 1.8V-2.7V power supply * Fully static operation: no clock or refresh required * Three state outputs * Data control for upper and lower bytes * Industrial temperature available * Available in Jedec Std 44-pin SOJ package, 44-pin TSOP (Type II), and 48-pin mini BGA
The ISSI IS62U6416LL is an ultra-low power, 1,048,576-bit static RAM organized as 65,536 words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques yields access times as fast as 200 ns with low power consumption. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access.

Note: 1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Notes: 1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 0.9V, input pulse levels of 0.4V to 1.8V and output loading specified in Figure 1. 2. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write. 3. Tested with the load in Figure 2. Transition is measured 500 mV from steady-state voltage.
