16 Interfaces
3.17 eMMC Interface
The LEC-iMX6 provides one onboard eMMC NAND Flash memory chip with a standard 8GB
storage capacity (other optional storage capacities are available.) The eMMC interface has an
8-bit width and complies with the MMC system specification. The LEC-iMX6 supports a second
8-bit wide eMMC interface at the SMARC connector (pins S26-S33.)
3.18 GPIO
The LEC-iMX6 provides 12 GPIO signals. Seven signals (GPIO 4, 5, 6, 8, 9, 10, 11) are gener-
ated by the 9535A GPIO expander, and the remaining five signals (0, 1, 2, 3, and 7) originate
from the iMX6 CPU and are designated for CAM0 and CAM1 (PWR and RST). The GPIO sig-
nals can be utilized for General Purpose IOs as well as camera enable pins and camera field
input, as defined in the SMARC specification.
3.19 AFB Alternate Function Block
The AFB is used for an MLB (Media Local Bus) interface. The MLB is only supported in auto-
motive and consumer parts.
3.20 LPC Debug
A 40-pin, front flip, DB40 connector allows access to debug and update the U-Boot boot loader,
BMC, and OS code on the module. (Refer to “Debug (DB40)” on page 25.)
