3.3V Single-Piece 4Mb Nonvolatile SRAM with Clock

Features ♦Single-Piece, Reflowable, 27mm x 27mm BGA Package Footprint ♦Internal Manganese Lithium Battery and Charger ♦Integrated Real-Time Clock ♦Unconditionally Write-Protects the Clock and SRAM when VCCis Out-of-Tolerance ♦Automatically Switches to Battery Supply when VCCPo

3.3V、单芯片、4Mb非易失SRAM，带有时钟

DS3050W由一个静态RAM、一个非易失(NV)控制器、一个2000年兼容的实时时钟(RTC)和一个内置的可充电锂锰(ML)电池组成。这些组件封装在一个表面安装的256焊球BGA模块中。VCC加在模块上时，它对ML电池进行充电，同时为时钟和SRAM供电，并允许修改时钟寄存器和SRAM内容。一旦VCC掉电或超出容限，控制器对存储器内容加以写保护，改由电池为时钟和SRAM供电。DS3050W还含有一个电源监视器输出(/RST)和一个用户可编程的中断输出(/IRQ/FT)。 \n• 单片、可回流焊、27mm x 27mm BGA封装 \n• 内置锂锰电池和充电器 \n• 集成实时时钟 \n• VCC超出容限后无条件写保护时钟和SRAM \n• VCC失效后自动切换至电池供电 \n• 复位输出可用作CPU监控 \n• 中断输出可用作CPU看门狗定时器 \n• 工业级温度范围(-40°C至+85°C);
