MYC-YA157C CPU Module

MYC-YA157C CPU Module

- ST STM32MP1 MPU based on 650MHz Dual Arm Cortex-A7 and 209MHz Cortex-M4 Cores
- 512MB DDR3, 4GB eMMC Flash
- On-board Gigabit Ethernet PHY
- 1.0mm pitch 164-pin Stamp Hole Expansion Interface
- Supports Running Linux OS
 



Measuring only 45mm by 43mm, the
MYC-YA157C CPU Module is a compact ST STM32MP1 powered System-on Module (SoM) that combines the STM32MP157 processor (STM32MP157AAC3), 512MB DDR3, 4GB eMMC as well as an integrated GigE PHY chip. A number of peripherals and IO signals are brought out through 1.0 mm pitch 164-pin stamp-hole (Castellated-Hole) expansion interface to make the module an excellent embedded controller for your system integration. Typical applications are industrial control, consumer electronics, smart home, medical and more other energy-efficient applications which require rich performance and low power.


MYC-YA157C CPU Module


The MYC-YA157C is running Linux OS. Based on Linux 4.19.9 kernel, MYIR provides abundant software resources for Yocto 2.6 based MYIR MEasy-HMI system, Yocto 2.6 based ST Weston system, Yocto 2.6 based MYIR MEasy-IOT system and Ubuntu 18.04 system including kernel and driver source code, STM32CubeProgrammer and STM32CubeMX tools to enable users to start their development rapidly and easily.


The MYD-YA157C development board is built around the MYC-YA157C CPU Module. It takes full advantages of the STM32MP157A MPU to explore a rich set of peripherals and interfaces to the base board including RS232, RS485, USB Type-C DRP, USB2.0 HOST, Gigabit Ethernet, WiFi/Bluetooth, CAN, Micro SD Card Slot, JTAG, RGB888 based LCD/HDMI, MIPI-DSI, etc. The MYD-YA157C development board is delivered with one Quick Start Guide, one Type-C cable, one USB to TTL serial cable and one WiFi/Bluetooth antenna to provide user a complete platform for evaluating and prototyping based on STM32MP1 series microprocessors. MYIR also offers MY-CAM002U Camera Module and MY-TFT070CV2 LCD Module as options for the board.

Hardware Specification

The MYC-YA157C CPU Module is using STMicroelectronics STM32MP157AAC3 Microprocessor with 12 x 12 mm, 0.5 mm pitch, TFBGA361 package which is among the STM32MP1 Series. The STM32MP1 series is based on a heterogeneous single or dual Arm Cortex-A7 and Cortex-M4 cores architecture, strengthening its ability to support multiple and flexible applications, achieving the best performance and power figures at any time. The Cortex-A7 core provides access to open-source operating systems (Linux/Android) while the Cortex-M4 core leverages the STM32 MCU ecosystem. It is available in 3 different lines which are pin-to-pin compatible:

  • STM32MP157: Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface and CAN FD
  • STM32MP153: Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz and CAN FD
  • STM32MP151: Single Cortex-A7 core @ 650 MHz, Cortex-M4 core @ 209 MHz
    Each line comes with a security option (cryptography & secure boot)
