Overview
The N08M1618L1A is an integrated memory device intended for non life-support medical
applications. This device is a 8 megabit memory organized as 524,288 words by 16 bits. The device is designed and fabricated using AMI Semiconductor’s advanced CMOS technology with reliability inhancements for medical users. 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. This device 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 a JEDEC standard BGA package.
