N01M0818L1A
1Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
128Kx8 bit Overview
The N01M0818L1A is an integrated memory device intended for non life-support (Class 1 or 2) medical applications. This device comprises a 1 Mbit Static Random Access Memory organized as 131,072 words by 8 bits. The device is designed and fabricated using NanoAmp's advanced CMOS technology with reliability inhancements for medical users. The base design is the same as NanoAmp's N01M0818L2A, which has further reliability processing for life-support (Class 3) medical applications. The device operates with two chip enable (CE1 and CE2) controls and output enable (OE) to allow for easy memory expansion. The N01M0818L1A 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 256Kb x 8 SRAMs

1. When the device is in standby mode, control inputs (WE and OE), address inputs and data input/outputs are internally isolated from any external influence and disabled from exerting any influence externally. 2. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.

1. Typical values are measured at Vcc=Vcc Typ., TA=25°C 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.
