Introduction

The EV98D91A 2-lead µVSFN mikroBUS compatible socket board is developed to be used with both serial EEPROM memory devices and security devices that are parasitically powered and are available in the 2-lead µVSFN package. The socket board can be used with any of the Microchip’s microcontroller boards that support a Mikroelektronika mikroBUS interface. The board’s dimensions match the large-size add-on board as defined in the mikroBUS specification. Through use of an adapter board, the socket board can also be used with Microchip microcontroller development boards that support an Xplained Pro interface. Having a socket board allows a customer to reuse the board with multiple 2-lead µVSFN sample devices for a given application or for multiple different applications. The 2-lead µVSFN mikroBUS socket board offers a less expensive option to configure and test the device and its features before mass production.

The board supports two different Single Wire Interfaces (SWI). These will be referred to as SWI and SWI-PWM. Any given Microchip cryptographic device will support either one or the other interface but never both. A jumper is provided on the board to select between these two interfaces.
