description

The TM893CBK32 is a 32-megabyte, dynamic random-access memory organized as four times 8388608×8 bits in a 72-pin, leadless single in-line memory module (SIMM). The SIMM is composed of 16 TMS417400DJ, 4194304 × 4-bit dynamic RAMs, each in 24/26-lead plastic small-outline J-lead (SOJ) packages mounted on a substrate with decoupling capacitors. The TMS417400DJ is described in the TMS417400 data sheet. The TM893CBK32 SIMM is available in the double-sided BK leadless module for use with sockets.
