Description

The TM497FBK32I is a 16M-byte dynamic random-access memory (DRAM) module organized as four times 4194304 × 8 bits in a 72-pin leadless single-in line memory module (SIMM). The SIMM is composed of eight TMS417409ADJ DRAMs, each in 24/26-lead plastic small-outline J-lead (SOJ) packages mounted on a substrate with decoupling capacitors. The TMS417409ADJ is described in the TMS416409A, TMS417409A data sheet (literature number SMKS893).

The TM497FBK32I SIMM is available in the single-sided BK leadless module for use with sockets. The TM497FBK32H/I features RAS access times of 50, 60, and 70 ns. This device is characterized for operation from 0°C to 70°C.

The TM497FBK32I is a 32M-byte DRAM organized as four times 8388608 × 8 bits in a 72-pin leadless SIMM. The SIMM is composed of sixteen TMS417409ADJ DRAMs.

The TM497FBK32I SIMM is available in the double-sided BK leadless module for use with sockets. The TM893GBK32H/I features RAS access times of 50, 60, and 70 ns. This device is characterized for operation from 0°C to 70°C.
