12-macrocell EPLD with 30 ns propagation delay
The CY7C330-33HC is an electrically programmable logic device (EPLD) from Infineon Technologies, offering 12 macrocells in a PAL-type architecture with a 30 ns propagation delay. This speed grade defines the maximum clock frequency the device can support — at 30 ns combinatorial delay, the part is suited for glue-logic replacement and state-machine designs running below roughly 33 MHz, where the propagation path through the programmable array and output logic settles within one clock period. Housed in a 28-LCC Window (J-Lead) package (supplier device package 28-JLCC, 11.43x11.43 mm), the windowed ceramic lid allows UV-erasable reprogramming — a feature that distinguishes it from one-time-programmable (OTP) PALs. The J-Lead footprint is surface-mount compatible, though the ceramic body and window add height compared to plastic packages.
Active lifecycle — no EOL risk for existing BOMs
Note that the part is RoHS non-compliant — it uses a lead-bearing solder finish typical of legacy ceramic packages. This is acceptable under many industrial and military exemptions, but RoHS-restricted assemblies (e.g. EU consumer goods) may require a waiver or an alternative finish variant. The windowed JLCC package is not generally offered in a lead-free version from the original manufacturer.
