Introduction

The EV97M19A is a mikroBUS™ extension board that demonstrates the capabilities of the Microchip SHA104 and SHA105. The SHA104 is intended for accessory side applications especially in the consumable and disposable applications. The SHA105 is a similar device, but is intended 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 that has the XPRO header by using the ATMBUSADAPTER-XPRO to ease development efforts. The on-board 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.
