The ATSHA204A is a member of the Microchip CryptoAuthentication™ family of high-security hardware authentication devices. It has a flexible command set that allows use in many applications, including the following:
• Anti-Counterfeiting
Validates that a removable, replaceable, or consumable client is authentic. Example of clients could be printer ink tanks, electronic daughter cards, medical disposables, or spare parts. The device can also be used to validate (authenticate) a software/firmware module or memory storage element.
• Protecting Firmware or Media
Validates code that is stored in flash memory at boot time to prevent unauthorized modifications (this is also known as secure boot), encrypts downloaded media files and uniquely encrypts code images to be usable on a single system only.
• Exchanging Session Keys
Securely and easily exchanges stream encryption keys for use by an encryption/decryption engine in the system microprocessor to manage a confidential communications channel, an encrypted download and similar items.
• Storing Data Securely
Stores secret keys for use by crypto accelerators in standard microprocessors. It can also be used to store small quantities of data necessary for configuration, calibration, ePurse value, consumption data, or other secrets. Programmable protection up through encrypted/authenticated reads and writes.

The MAX1795/MAX1796/MAX1797 are high-efficiency, step-up DC-DC converters intended for small portable hand-held devices. These devices feature Maxim’s True Shutdown™ circuitry, which fully disconnects the output from the input in shutdown, improves efficiency, and eliminates costly external components. All three devices also feature Maxim’s proprietary LX-damping circuitry for reduced EMI in noise-sensitive applications.
For additional in-system flexibility, a battery monitoring comparator (LBI/LBO) remains active even when the DC-DC converter is in shutdown.
The input voltage range is +0.7V to VOUT, where VOUT can be set from +2V to +5.5V. Startup is guaranteed from +0.85V. The MAX1795/MAX1796/MAX1797 have a preset, pin-selectable 5V or 3.3V output. The output can also be adjusted to other voltages, using two external resistors. The three devices differ only in their current limits, allowing optimization of external components for different loads: The MAX1795, MAX1796, and MAX1797 have current limits of 0.25A, 0.5A, and 1A, respectively.
