Lattice Semiconductor has marked the GAL16V8Z-15QJ as Obsolete.
Parametric fit — 8 macrocells at 15 ns
The part integrates 8 macrocells in an EE PLD fabric. The 15 ns maximum propagation delay (tpd(1)) sets the ceiling for registered logic — a state machine clocked at 66 MHz has zero setup margin at this speed grade; designs targeting 50 MHz or lower leave usable slack. The operating temperature range is 0°C to 75°C (TA), commercial grade. Not qualified for extended industrial or automotive ambient conditions. The package is a 20-LCC with J-leads (20-PLCC, 9x9 mm body) — the J-bend footprint uses the same PCB land pattern as standard PLCC-20 sockets, but the reflow profile must account for the lead-free solder joint standoff.
Board integration — 20-PLCC footprint
Surface-mount 20-PLCC (9x9 mm body) with J-leads. The J-lead geometry provides a visual solder-joint inspection window on the outer rows, unlike a QFP with hidden gull-wing toes. Belongs to the GAL16V8 series — the base architecture is a registered/combinatorial PLD with 8 output logic macrocells, each configurable as registered or combinatorial with programmable polarity. Programming is via standard PLD programmers supporting the JEDEC fuse map; the EE cells retain the configuration without a backup battery.
