ST STM32MP157C-DK2 User Manual

Introduction
The STM32MP157A-DK1 and STM32MP157C-DK2 Discovery kits are designed as complete demonstration and development
platforms for STMicroelectronics Arm
®
-based dual Cortex
®
-A7 32 bits and Cortex
®
-M4 32 bits MPUs in the STM32MP1 Series
and their STPMIC1 companion chip. They leverage the capabilities of STM32MP1 Series microprocessors to allow users
develop applications using STM32 MPU OpenSTLinux Distribution software (such as STM32MP1Starter) for the main processor
and STM32CubeMP1 software for the co-processor.
They feature 16-bit DDR3L 4 Gbits at 533 MHz, MIPI DSI
SM
2 lanes at 1 Gbps, USB Type-C
™
DRP HS port, USB Type-A Host
HS ports, audio codec with analog audio input / output, microSD
™
card high-speed mode up to 50 MHz, Gigabit Ethernet,
HDMI
®
up to 720p60 (1280 × 720), 40-pin extended GPIOs, Arduino
™
, Wi‑Fi
®
802.11b/g/n, Bluetooth
®
Low Energy 4.1, and ST-
LINK/V2.1 (UART console).
The STM32MP157C-DK2, shown with display removed in Figure 1 and Figure 2, is used as a reference design for user
application development. It cannot be considered as the hardware design of a final application.
The hardware features of the Discovery kits are available for users to develop their applications: USB, Ethernet, LTDC, TFT
LCD MIPI DSI
SM
, microSD
™
card, audio codec, user buttons, Wi‑Fi
®
, and Bluetooth
®
Low Energy. Extension headers allow easy
connection of an Arduino
™
board for a specific application.
An ST-LINK/V2-1 is integrated on the board, as embedded in-circuit debugger and programmer for the STM32 MPU and the
USB Virtual COM port bridge.
