MCP1415/6的特性：
The MCP1415/16 devices are small footprint Low-Side MOSFET drivers capable of supplying 1.5A peak output current in a SOT23 5L package. The MCP1415 is an inverting lowside driver meaning that when the input signal is high, the output is low. The MCP1416 is a non-inverting lowside driver meaning that when the input signal is high, the output signal is also high. Although the name of the device is MOSFET driver, these devices have other applications besides driving the gate of a MOSFET. These devices are also used to direct drive a small DC motor, act as buffers for high speed data lines, and level translators to interface low voltage to high voltage.（mcp1415 / 16设备占地面积小，低侧MOSFET驱动器可以提供1.5A的峰值输出电流在SOT23 5l包。这是一个反相低边驱动器mcp1415意义，当输入信号为高，产量低。这是一个非反相驱动mcp1416偏低意味着当输入信号为高，输出信号也高。虽然该设备的名称是MOSFET驱动器，但这些设备除了驱动MOSFET栅极之外还有其他应用。这些设备也被用来直接驱动小型直流电动机，作为高速数据线的缓冲器，电平转换器将低压到高电压连接。）

MIC5205的特性：
The MIC5205 is an efficient linear voltage regulator with ultra-low noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (600μA at 100mA output). The MIC5205 offers better than 1% initial accuracy.
Designed especially for handheld, battery-powered devices, the MIC5205 includes a CMOS- or TTL-compatible enable/shutdown control input. When shut down, power consumption drops nearly to zero. Regulator ground current increases only slightly in dropout, further prolonging battery life.
Key MIC5205 features include a reference bypass pin to improve its already excellent low-noise performance, reversed-battery protection, current limiting, and over-temperature shutdown.
The MIC5205 is available in fixed and adjustable output voltage versions in a small SOT-23-5 package.
For low-dropout regulators that are stable with ceramic output capacitors, see the μCap MIC5255/MIC5256/MIC5247.（是一种有效的mic5205线性稳压器具有低噪声输出，非常低压差电压（一般在150mA 17mv在轻负载和165mv），和非常低的接地电流（600μ在100mA输出）。的mic5205提供了优于1%的初始精度。
专为手持式，电池供电的设备，该mic5205包括一个CMOS或TTL兼容的启用/关闭控制输入。关机时，耗电量几乎降到零。调节器接地电流仅略有下降，进一步延长电池寿命。
关键mic5205特点包括一个参考旁路引脚提高已经非常出色的低噪声性能，反向电池保护、电流限制和过温关断。
的mic5205固定和可调输出电压在一个小型SOT-23-5封装版本可用。

ATSHA204A的特性：
The Microchip SHA-based CryptoAuthentication crypto element devices have been architected to provide flexible user-configured security to enable a wide range of authentication models. The ATSHA204A is the first device in the SHA device group. The ATECC108A and ATECC508A are supersets of the ATSHA204A and thus upward compatible. As with all CryptoAuthentication devices, the ATSHA204A is easy to design in with no crypto expertise required.
Secure Hash Algorithm (SHA) algorithms are widely used in most cryptographic systems and remain an important component in most modern authentication protocols. These devices support the SHA-256 standard. The ATSHA204A is the most cost-effective solution in the Microchip CryptoAuthentication portfolio. It integrates the SHA-256 hash algorithm with a 4.5Kb EEPROM and provides robust hardware authentication using secure key/data storage. The tiny packaging and a single-wire interface make the device ideal for handheld electronic systems and any space-constrained embedded system.
CryptoAuthentication devices in the SHA mode include client and host security capabilities that offload key storage and algorithm execution from the microcontroller, significantly reducing system cost and complexity. SHA based symmetric authentication is fast relative to asymmetric approaches, making the ATSHA204A a good choice with speed (and/or cost) are important considerations. CryptoAuthentication devices have full metal shields over all of the internal circuitry, so that if an attacker cuts or short circuits any trace in the shield, the product stops functioning. Additional security features include internal clocks and voltage generation, encrypted memories, tamper detection, and fully secure production test methodologies. With the ATSHA204A implementing host-side security to provide a full system solution is now easier than ever.（微芯片的基础cryptoauthentication隐元沙装置已设计提供灵活的用户配置的安全，使广泛的认证模型。的atsha204a在沙装置组装置。的atecc108a和atecc508a的atsha204a超集从而向上兼容。与所有的cryptoauthentication设备的atsha204a容易设计，在没有加密的专业要求。
安全散列算法（SHA）广泛应用于大多数密码系统中，仍然是现代认证协议中的一个重要组成部分。这些设备支持SHA-256标准。是的atsha204a芯片cryptoauthentication组合具成本效益的解决方案。它集成了SHA-256哈希算法和4.5kb EEPROM和提供了强大的硬件认证使用安全密钥/数据存储。微型封装和单线接口使该设备成为手持电子系统和任何空间受限嵌入式系统的理想选择。
在沙模式cryptoauthentication设备包括客户端和主机的安全功能，将密钥存储和算法执行的微控制器，大大降低了系统的成本和复杂性。沙的对称认证快速相对不对称的方法，使atsha204a速度的一个很好的选择（或成本）是重要的考虑因素。cryptoauthentication设备有全金属屏蔽所有的内部电路，这样如果一个攻击者削减或短路屏蔽中的任何痕迹，产品停止运作。其他安全功能包括内部时钟和电压生成、加密存储器、篡改检测和完全安全的生产测试方法。与atsha204a实现主机侧安全提供一个完整的系统解决方案现在比以往更容易。）
