EM512D16 Advance Information
EM512D16
512Kx16 bit Ultra-Low Power Asynchronous Static RAM Overview
The EM512D16 is an integrated memory device containing a low power 8 Mbit Static Random Access Memory organized as 524,288 words by 16 bits. The base design is the same as NanoAmp's standard low voltage version, EM512W16. The device is fabricated using NanoAmp's advanced CMOS process and high-speed/ultra low-power/ low-voltage circuit technology. The device pinout is compatible with other standard 512K x 16 SRAMs. The device is designed such that a creative user can improve system power and performance parameters through use of it's unique page mode operation.
Features

1. When UB and LB are in select mode (low), I/O 0 - I/O 15 are affected as shown. When LB only is in the select mode only I/O 0 - IO7 are affected as shown. When UB is in the select mode only I/O 8 - I/O 15 are affected as shown. If both UB and LB are in the deselect mode (high), the chip is in a standby mode. 2. When the device is in standby mode, control inputs (WE, O E, 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.

1. This device assumes a standby mode if the chip is disabled (CE1 high or CE2 low). It will also go into a standby mode whenever if both UB and LB are high. In order to achieve low standby current all inputs must be within 0.2 volts of either VCC or VSS. 2. The Chip is Disabled when CE1 is high or CE2 is low. The Chip is Enabled when CE1 is low and CE2 is high.
