The Texas Instruments TMS4161-15FME is a 65536 x 1 bit Video DRAM, organized as 64K x 1. This NMOS technology component features a 150ns maximum access time and operates in asynchronous mode. Key characteristics include RAS-only refresh and a dual-port architecture with a 256x1 SAM port, enabling simultaneous access for display refresh and data updates. The device is housed in a PQCC-22 (R-PQCC-J22) package, supporting surface mounting with a 1.27mm terminal pitch. Operating voltage is within a 4.5V to 5.5V range, with a nominal supply of 5V. This Video DRAM is suitable for applications requiring high-speed memory for graphics and display controllers, commonly found in consumer electronics and industrial systems. The output characteristics are 3-state.
