Microchip Technology EV97M19A Evaluation Board

Microchip Technology EV97M19A Evaluation Board is a mikroBUS™ extension board demonstrating the capabilities of Microchip SHA104 and SHA105. The SHA104 is intended for accessory side applications, especially consumable and disposable applications. The SHA105 is a similar device designed for host-side applications where mutual authentication is desirable. The two devices provide a complete mutual symmetric authentication for commercial and industrial applications.

The board is designed to be used with the CryptoAuth Trust Platform and other Microchip development platforms that contain a MikroElektronica mikroBUS header. The EV97M19A can also connect to any board with the XPRO header using the ATMBUSADAPTER-XPRO to ease development efforts. The onboard Microchip host and accessory devices simplify the development of your authentication system.

The EV97M19A contains the following Microchip devices: SHA105 host device with an I2C interface, SHA104 accessory device with an I2C interface, and SHA104 accessory device using Microchip’s proprietary SWI-PWM interface.
