The 7.5 ns tpd(1) max propagation delay is the combinatorial path ceiling; for a 3.3 V CPLD this means glue logic between a 100 MHz bus and a slower peripheral closes timing with margin, provided the board trace delay stays under 1 ns. ## Board integration and footprint The 48-TQFP (7x7 mm) body with 0.5 mm pitch requires a 4-layer board for clean fan-out of the 32 I/O — the inner layers handle the VCC and GND planes, while the outer layers route the signal traces. The exposed pad on the bottom is not present; thermal management relies on the 48 leads conducting heat to the board copper. In-system programmable via JTAG — the TDI, TDO, TMS, and TCK pins are dedicated; no external programming voltage is needed. The 3.3V VCCIO rail powers the JTAG interface, so the programmer cable must match the logic level.","metaTitle":"Lattice LC4032V-75TN48I CPLD, 32 Macrocells, 7.5 ns","metaDescription":"Lattice ispMACH 4000V CPLD, 32 macrocells, 7.5 ns tpd, 32 I/O, -40 to 105°C, 48-TQFP.

The 48I variant offers 32 I/O in a 48-TQFP package, while the 44I variant provides 30 I/O in a 44-TQFP. The 48I is the higher-I/O option; the 44I has a smaller footprint.
