ISPGDX240VA-7B388I

The Lattice Semiconductor ISPGDX240VA-7B388I is an in-system programmable digital crosspoint switch from the ispGDX family. This device offers 240 I/O channels with flexible "Any Input to Any Output" routing capabilities, addressing applications such as programmable PCB interconnect, bus interface integration, and jumper/switch replacement.

Engineered with high-performance E2CMOS technology, the ISPGDX240VA-7B388I operates at a 3.3V core power supply. It boasts a fast 4.5ns input-to-output delay and a 4.0ns clock-to-output delay, supporting a maximum clock frequency of 200MHz. The device features individually programmable TTL/3.3V/2.5V compatible input thresholds and output levels. It also includes a low quiescent current of 20.0mA and a 24mA IOL drive capability with an optional programmable slew rate control.

The flexible architecture allows for combinatorial, latched, or registered inputs/outputs, with individual I/O tri-state control and polarity control. It supports dedicated clock/clock enable inputs or programmable clocks/enables from I/O pins. The device offers a single-level 4:1 dynamic path selection and a programmable wide-MUX cascade feature supporting up to 16:1 MUX. Programmable pull-ups, bus hold latches, and open-drain options are available on I/O pins. Outputs are tri-stated during power-up for live insertion compatibility.

This device is supplied in a space-saving, fine-pitch 388-BGA package, specifically the 388-BBGA (35x35) variant. It is designed for surface mount applications and operates within an industrial temperature range of -40°C to 85°C.
