8Mb Ultra-Low Power Asynchronous CMOS SRAM
512K × 16 bit Overview
The N08L163WC2A 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 NanoAmp’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 N08L163WC2A 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.
