It operates on a 4.75 V to 5.25 V supply. ## Programming and JEDEC file support As an electrically erasable PAL, the PAL18L4CNL is programmed using standard PAL programmer hardware that supports 28-pin PLCC devices. A JEDEC fuse-map file is required; most legacy PAL compilers (CUPL, PALASM) can generate the.JED output. The part is in-system reprogrammable if the programmer supports the PLCC footprint — no UV erasure needed.","metaTitle":"PAL18L4CNL Electrically Erasable PAL Device, 40 ns, 28-PLCC","metaDescription":"PAL18L4CNL electrically erasable PAL device from the PAL family. 40 ns propagation delay, 5 V supply, 28-PLCC package.
