I am preparing router specification for upcoming projects and unable to find following parameters related to NCS540 routers in the cisco datasheets.
can someone help me to get the above parameters.

These are not easy to answer because of how TCAM is split between LEM and LPM and with anchor prefixes as well as other considerations such as these are unidimensional scale numbers. We don't make a difference between rib and fib, only bgp paths (think multipath) and rib on tortin.
In order of column is as below.
column 1 (N540-24Z8Q2C-SYS, N540(X)-ACC-SYS (NCS-540 Tortin))
column 2 (N540X-12Z16G-SYS-D/A, N540-28Z4C-SYS-D/A, N540-12Z20G-SYS-D/A, N540-FH-CSR-SYS)
column 3 (N540X-6Z18G-SYS-D/A, N540X-4Z14G2Q-D/A, N540X-8Z16G-SYS-D/A)
column 4 (N540-24Q8L2DD-SY)
Max nos. of Active Route Table (FIB) IPv4 prefixes and IPv6 prefixes.
Max nos. of routing table (RIB) for IPv4 and IPv6.
IPv4 BGP/RIB only | 18M/12M | 8M | 8M | 10M |
IPv6 BGP/RIB only | 17M/12M | 8M | 8M | 10M |
Max nos. of IS-IS/OSPF neighbors.
ISIS peers | 50 | 50 | 50 | 300 |
OSPF peers | 100 | 100 | 50 | 300 |
Max nos. of IPv4 ACLs and IPv6 ACLs.
IPv4 / IPv6 Ingress unique ACLs | 127 | 127 | 127 | 127 |
IPv4 / IPv6 Egress unique ACLs | 255 | 255 | 255 | 255 |
IPv4 Ingress ACEs | 4k | 2k | 2k | 4k |
IPv6 Ingress ACEs | 2k | 2k | 2k | 2k |
IPv4 Egress ACEs | 4k | 2k | 2k | 4k |
IPv6 Egress ACEs | 2k | 2k | 2k | 2k |
Max nos. of BGP neighbors.
BGP neighbors | 110 | 110 | 110 | 500 |

Hi,
Not the kind of information you are going to find int the Datasheet, some of them you probably will not find at all like how many BGP neighbord?
Example, If the routing table is up to 4M IPv4 routes and you add a BGP neighbord which has 4M IPv4 routes and you accept all those routes, then, you can have only one neighbord or your crash the router.
.Some of this information you get from the resseler.
But, some informatio you can get from ciscos docs, not necessarily datasheet.
Used for unicast route scale up to 2M or 4M IPv4 Routes
I am attaching a pdf with most of this information.

this varies quite a bit depends on the NCS 540 variant, as an example 100 OSPF peers for Tortin/Big Bend and 300 for Arches variant.
