N04L63W2A Datasheet | onsemi

Overview The N04L63W2A is an integrated memory device containing a 4 Mbit Static Random Access Memory organized as 262,144 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 N04L63W2A 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 -40o C to +85o C and is available in JEDEC standard packages patible with other standard 256Kb x 16 SRAMs ..
