N08L6182A
8Mb Ultra-Low Power Asynchronous CMOS SRAM
512K x 16bit Overview
The N08L6182A is an integrated memory device containing a 8 Mbit Static Random Access Memory organized as 524,288 words by 16 bits. The device is designed and fabricated using ON Semiconductor's advanced CMOS technology to provide both high-speed performance and ultra-low power. The device operates with two chip enable (CE1 and CE2) controls and output enable (OE) to allow for easy memory expansion. Byte controls (UB and LB) allow the upper and lower bytes to be accessed independently and can also be used to deselect the device. The N08L6182A is optimal for various applications where low-power is critical such as battery backup and hand-held devices. The device can operate over a very wide temperature range of -40oC to +85oC and is available in JEDEC standard packages compatible with other standard 512Kb x 16 SRAMs.

1. When UB and LB are in select mode (low), I/O0 - I/O15 are affected as shown. When LB only is in the select mode only I/O0 - I/O7 are affected as shown. When UB is in the select mode only I/O8 - I/O15 are affected as shown. 2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are internally isolated from any external influence and disabled from exerting any influence externally. 3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit. 4. The device will consume active power in this mode whenever addresses are changed. Data inputs are internally isolated from any expernal influence.

1. Typical values are measured at Vcc=Vcc Typ., TA=25C and not 100% tested. 2. This parameter is specified with the outputs disabled to avoid external loading effects. The user must add current required to drive output capacitance expected in the actual system. 3. This device assumes a standby mode if the chip is disabled (CE1 high or CE2 low). In order to achieve low standby current all inputs must be within 0.2 volts of either VCC or VSS.

Note: Page mode operation is a method of addressing the SRAM to save operating current. The internal organization of the SRAM is optimized to allow this unique operating mode to be used as a valuable power saving feature. The only thing that needs to be done is to address the SRAM in a manner that the internal page is left open and 16-bit words of data are read from the open page. By treating addresses A0-A3 as the least significant bits and addressing the 16 words within the open page, power is reduced to the page mode value which is considerably lower than standard operating currents for low power SRAMs.
