德州TI系列DAC7564芯片介绍及IC解密

　近期以来，龙芯世纪科技针对德州仪器TI系列IC解密的技术攻关研究又有了新的突破，继此前成功破解一批典型TI芯片之后，此次又有一大批TI单片机被成功破解，且针对TI系列芯片解密，龙芯世纪科技的解密技术已经相当成熟，不仅解密成功率高、可靠性强，而且解密周期短、价格低，可以为客户带来更多经济效益。
　DAC7564芯片解密是我们成功破解的典型TI单片机，如果客户有DAC7564解密等TI芯片解密需求，请与龙芯世纪科技联系咨询更多解密详情。下面，我们就将简单介绍一下关于DAC7564芯片的主要性能特征，供大家参考借鉴。

   The DAC7564 is a low-power, voltage-output, four-channel, 12-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/°C internal reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.02% and can source up to 20mA at the VREFH/VREFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC7564 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces.
   The DAC7564 incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device.
