† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TMS41x800 series is a set of high-speed, 16777216-bit dynamic random-access memories (DRAMs) organized as 2097152 words of eight bits each. It employs TI's state-of-the-art EPIC technology for high performance, reliability, and low power.

These TMS41x800 series  devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. All addresses and data-in lines are latched on-chip to simplify system design. Data out is unlatched to allow greater system flexibility.The TMS416800 and TMS417800 are offered in a 28-lead plastic surface-mount SOJ package (DZ suffix). This package is characterized for operation from 0°C to 70°C.
