AT64DB641E-MHN-T – ADESTO

The AT64DB641E-MHN-T is a 64Mb (8M x 8) asynchronous SRAM manufactured by Atmel (now Microchip). This specific part number designates a device with a low-power, high-performance architecture optimized for embedded systems requiring fast access times and low power consumption. It operates from a single 3.3V supply voltage with a tolerance typically ranging from 2.7V to 3.6V. The device utilizes a fast page mode for improved data throughput, achieving access times as low as 15ns. Packaged in a 54-pin TSOP II (Thin Small Outline Package), it’s suited for space-constrained applications._x000D_

The AT64DB641E-MHN-T’s asynchronous operation eliminates the need for external clock signals, simplifying system design and reducing component count. Its high density and fast access speed make it ideal for applications such as frame buffers in graphics processing, high-speed data caching in embedded processors, or as a general-purpose memory solution where low latency and high bandwidth are critical. The ‘-MHN-T’ suffix indicates a commercial temperature range (-40°C to +85°C) and a lead-free, RoHS-compliant package. Its low power consumption makes it particularly attractive for battery-powered or portable devices, offering a balance between performance and energy efficiency.
