The TM124GU8A is a dynamic random-access  
memory module organized as 1 048 576 × 8 in a  
30-pin leadless single in-line memory module  
(SIMM).  
PIN NOMENCLATURE  
The TM124GU8A is composed of two TMS44400,  
1 048 576 × 4 bit dynamic RAMs in 20/26-lead  
plastic small-outline J-lead packages (SOJs).

5-V Supply  
The TM124GU8A is mounted on a substrate with  
decoupling capacitors. The onboard capacitors  
eliminate the need for bypassing on the  
motherboard and offer superior performance over  
equivalent leaded capacitors due to reduced lead  
inductance. With the elimination of bypass  
capacitors on the motherboard, reduced PC  
board size, and fewer plated through-holes, a cost  
savings can be realized.

The TM124GU8A features RAS access times of 60 ns, 70 ns, and 80 ns. All inputs and outputs, including clocks,  
are compatible with Series 74 TTL. All address lines and data in are latched on-chip to simplify system design.  
Data out is unlatched to allow greater system flexibility.  
The TM124GU8A is characterized for operation from 0°C to 70°C.
