ConnectCore ? f or ? i .M X 5 1 ?
Keypad
The module provides a keypad port that can be used as a keypad matrix interface or as
general purpose input/output.
The Keypad port is designed to interface with the keypad matrix with 2-point contact or 3-
point contact keys. The Keypad port is designed to simplify the software task of scanning a
keypad matrix. With appropriate software support, the Keypad port is capable of detecting,
debouncing, and decoding one or multiple keys pressed simultaneously on the keypad.

Memory Cards
The ConnectCore for i.MX51 module provides up to four MMC/SD/SDIO interfaces.
??? MultiMediaCard
(MMC)
This is a universal low-cost data storage and communication media that is designed to
cover a wide area of applications including mobile video and gaming, WLAN or other
wireless networks. Old MMC cards are based on 7-pin serial bus with a single data pin,
while the newer high-speed MMC communication is based on an advanced 11-pin serial
bus designed to operate at lower voltage.
??? Secure
Digital (SD) card
This is an evolution of earlier MMC technology. It is specifically designed to meet the
security, capacity, performance, and environment requirements inherent in newly emerg-
ing audio and video consumer electronic devices. The physical form factor, pin assign-
ment and data transfer protocol are forward compatible with MMC, with some additions.
Under the SD protocol, an SD card can be categorized as memory card, I/O card, or
combo card (having both memory and I/O functions).
The main features of the Memory Card interfaces are the following:
??? Designed
to work with MMC, MMC plus, MMC RS, SD memory, miniSD memory, SDIO,
and SD Combo. Compatible with the following specifications:
– MMC System Specification Version 4.2
– SD Host Controller Standard Specification Version 2.0
