Product Details
The GR3281 is an industrial temperature range 32,768 word by 8 bits (32k x 8) non-volatile static RAM fabricated from advanced silicon gate CMOS technology and a high reliability lithium power cell.
The 28W dil pinout of the GR3281 conforms to the JEDEC standards and is fully compatible with normal static RAM.
The 28W dil pinout of the GR3281 conforms to the JEDEC standards and is fully compatible with normal static RAM.
The power down circuit is fully automatic and is referenced at 4.5V. At this point the GR3281 is write protected by an internal inhibit function for data protection and the memory contents are retained by the lithium power source.
Power down is very fast, this being essential for data integrity, taking a maximum 15 microseconds to power down from 5V to 0V. This is much faster than any system power failure conditions; therefore there are no special conditions required when installing the GR3281.
The GR3281 can, without external power, retain data almost indefinitely; the limiting factor being the shelf life of the lithium power cell, typically 10 years.
