In LPC Microcontroller like LPC43xx, LPC177x_8x,LPC407x_8x it can be 4 or 8. CL is CAS latency which is explained in JEDEC as Quote: The number of clock cycles occurring between the registration of a read command and the active clock transition coincident with the availability of the first resultant output data.,
