TMS4C2972DT-26

Product Summary

The TMS4C2972DT-26 is a field memory (FMEM) that is upwardly and pin-to-pin compatible with the TMS4C2970 and TMS4C2971, except for the consequences of the block size change (40 instead of 80 words per block) on old data access mode enabling (see the section titled "old-/new-data access"). The TMS4C2972DT-26 is a two-port memory; data is written in through a 12-bit-wide write port and is read out through a 12-bit-wide read port. Both ports may be operated simultaneously and/or asynchronously. Dynamic storage cells are employed for main data memory to achieve high storage density, but the TMS4C2972DT-26 refreshes its cells automatically so that device operation appears fully static to the user. All internal pointers and registers are fully static so that read and write operations can be interrupted for indefinite periods of time without loss of data.
