The 25 ns propagation delay sets the system clock ceiling. The eight macrocells handle glue-logic consolidation such as address decoding and state machine sequencing.
This part is RoHS non-compliant. The hermetic ceramic package and lead-bearing solder terminations are standard for mil/aero programs exempt from RoHS restrictions.
The PAL20R8A-2ML/883B has a 25 ns propagation delay, which defines the maximum registered logic path timing for the system clock.
No, the PAL20R8A-2ML/883B is RoHS non-compliant due to its hermetic ceramic package with lead-bearing terminations, which is standard and acceptable for military and aerospace applications under the RoHS exemption.
The package is a 28-CLCC (28-pin ceramic leaded chip carrier) with a body size of 11.43x11.43 mm, surface-mount, hermetic ceramic.
Yes, it programs with standard PAL programmers supporting the 20R8 architecture using a 28-pin CLCC adapter; the programming algorithm is identical to the commercial PAL20R8A.
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) for current pricing and availability — we confirm both at quote time.
The 883B military-grade variant is specified over the full military temperature range (-55°C to +125°C), consistent with MIL-STD-883 Class B screening requirements.
The /883B suffix indicates full MIL-STD-883 Class B processing and screening — burn-in, temperature cycling, and electrical test over the military temperature range — whereas the base PAL20R8A-2ML is typically a commercial or industrial grade part without that screening.
