What is the memory density and organization?

The device has a density of 2 gigabits (2Gb) and is organized as 128M x16 (128 mega-words by 16 bits).

What does the -3 speed grade mean?

In ISSI DDR2 part numbering the -3 speed grade corresponds to operation up to 333MHz clock frequency (DDR2-667 data rate) at a CAS latency of 5.

What package does the IS43DR16128A-3DBL use?

It is supplied in an 84-ball FBGA (fine-pitch ball grid array) package, measuring approximately 10.5mm x 13.5mm.

What is the difference between IS43DR16128A-3DBL and IS43DR16128A-3DBLI?

They share the same 2Gb 128M x16 DDR2 die and speed grade. The trailing 'I' on the -3DBLI denotes the industrial temperature grade (-40C to +85C), while the -3DBL without the 'I' is the commercial-grade version (0C to +70C).

Is the IS43DR16128A-3DBL still available?

This is a hard-to-find, NRND DDR2 part with little to no authorized-distributor stock. Pacific Component Xchange maintains inventory of scarce parts like this. Submit an RFQ for current pricing, availability, and lead time.

The IS43DR16128A-3DBL is a 2-gigabit DDR2 SDRAM from Integrated Silicon Solution, Inc. (ISSI), organized as 128M x16. It operates from a 1.8V supply and is supplied in an industry-standard 84-ball FBGA package. The “-3” speed grade supports operation up to 333MHz (DDR2-667) at a CAS latency of 5, making it well suited to embedded, industrial, and networking designs that require a reliable, long-lifecycle DDR2 memory device.

ISSI is a recognized supplier of memory products engineered for extended product lifecycles, which makes the IS43DR16128A family a popular choice for systems that must remain in production long after mainstream PC-grade DDR2 has been discontinued.
