TI TMS44460-70DR

The TMS4x460 series are high-speed, 4194304-bit dynamic random-access memories organized as 1048576 words × 4 bits. The TMS4x400P series are high-speed, low-power, self-refresh, extended-refresh 4194304-bit DRAMs, also organized as 1048576 words × 4 bits. Both series employ state-of-the-art enhanced-performance implanted CMOS (EPIC) technology to achieve high performance, high reliability, and low power consumption.

These devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. All address and data inputs are on-chip latched to simplify system design. Data outputs are unlatched to provide greater system flexibility.

Four independent CAS pins (CAS1–CAS4) enable independent I/O operation, allowing the device to operate in parity mode. The TMS44460 also supports enhanced page mode operation, similar to the TMS44400.

The TMS4x400 and TMS4x400P are available in 24/26-pin plastic small-outline (TSOP) packages (DGA suffix) and 300-mil 24/26-pin plastic surface-mount SOJ packages (DJ suffix). Both packages support an operating temperature range of 0°C to 70°C.
