Texas Instruments High-Performance Analog Memory TMS55166-60DGH

The TMS55166-60DGH is a high-speed dual-ported video RAM with a capacity of 262,144 words organized as 16 bits each. It features a split-register-transfer function that allows simultaneous and asynchronous access from both the dynamic random-access memory (DRAM) and the serial-access memory (SAM) ports. The device supports data transfer rates of up to 55 MHz and includes a programmable split-register stop point, enhancing flexibility in data handling. This memory IC is designed for compatibility with TTL logic levels and adheres to JEDEC standards. It operates on a single 5.0 V power supply and offers various write functions, including write-per-bit and byte write capabilities, which facilitate selective data manipulation. The TMS55166-60DGH also supports enhanced page mode and extended-data-output (EDO) operation for improved access times. The device is housed in a 64-pin small-outline gull-wing-leaded package, suitable for surface mounting, making it a practical choice for applications requiring efficient memory access and high performance in video processing tasks.
