EP1810LC-45 – ALTERA

The EP1810LC-45 is a 5V-operated, erasable programmable logic device (EPLD) from Altera’s EP1800 series, fabricated using a CMOS EPROM process. This specific variant, designated by the “-45” suffix, indicates a maximum propagation delay of 45 nanoseconds from input to output, representing its speed grade. The device features a macrocell architecture consisting of programmable AND and fixed OR logic, enabling implementation of complex combinational and sequential functions. The EP1810LC offers a high I/O pin count, suitable for address decoding, peripheral control, and state machine applications. Note that the ALTERA NOT RoHS COMP. designation signifies that this particular part number does not comply with the Restriction of Hazardous Substances Directive, potentially limiting its use in certain applications and regions.
