Are faster SRAM chips backwards-compatible with their slower counterparts in the same series? For example: a 6116LP-3 in place of a 6116LP-4?
Does the same hold true for 2114's, 6514's, etc.?
If they are, is there a limit? I got a bit confused when comparing datasheets. I am working on an old synthesizer and trying to build up an assortment of spare parts for the future. It has a Z80 running at 2.5 MHz. as the processor. It has an HM6116LP-4, a couple D444C-5614's, and a couple M5L-2114LP-3.
In the case of the 6514's I came across some D444C-6514-2 chips and it got me a bit curious about this.
Thanks.
