1.3 Component Description

The EV71E60A development board includes the following integrated circuits:

MEC1723

Microchip’s MEC1723 is a highly configurable, mixed-signal advanced I/O controller designed for desktop and notebook PCs, provided in a 144-pin WFBGA package. The device contains a 32-bit ARM® Cortex-M4F or M4 processor core with closely coupled memory for optimal code execution and data access. This device includes a wide range of security features for authentication, data integrity, data privacy, secure boot, root-of-trust and a NIST-certified true random number generator.

MCP2200

Microchip’s MCP2200, in a 20-pin UDFN package, converts a USB signal to UART to facilitate communication with the MEC1723 embedded controller. The device communicates through a USB 2.1 interface.

MCP1826S

The development board includes two Microchip MCP1826S low drop-out (LDO) regulators. The MCP1826S/3.3V generates a 3.3V supply from the USB 5.0V input. The MCP1826S/1.8V generates a 1.8V supply from the output of the 3.3V LDO.

GD25LR512MFFIR

The development board includes a socketed Gigadevice GD25LR512MFFIR 512 Mbit QSPI memory device, capable of operating at a 1.8V supply. The socketed interface allows users to select the memory supplier of their choice. The J26 jumper controls the VTR2 power rail, enabling the memory device to operate at either 1.8V or 3.3V.
CAUTION: If the memory is switched, it is the user’s responsibility to validate the operating voltage of the selected device and set the J26 jumper accordingly.
