description

The TM497EU9 is a 4M-byte dynamic random-access memory (RAM) organized as 4194304 × 9 bits [bit nine (D9, Q9) is generally used for parity and is controlled by CAS9\] in a 30-pin leadless single-in-line memory module (SIMM). The SIMM is composed of two TMS417400DJ, 4194304 × 4-bit dynamic RAMs, each in a 24/26-lead plastic small-outline J-lead (SOJ) package, and one TMS44100DJ, 4194304 × 1-bit dynamic RAM in a 20/26-lead plastic SOJ package, mounted on a substrate with decoupling capacitors.

The TM497EU9 is available in the U single-sided, leadless module for use with sockets and is characterized for operation from 0°C to 70°C.
