The MYC-C437X
CPU Module is a low-cost compact-sized SOM (System on Module) based on 1GHz Sitara AM437x (AM4376, AM4377, AM4378, AM4379) ARM Cortex-A9 processors from Texas Instruments
(TI), featuring 3D graphics acceleration for rich graphical user interfaces, PRU-ICSS for
industrial protocols, improved Vector Floating
Point (VFP) unit
and other peripherals and interfaces support like Quad-SPI, dual parallel cameras, two independent
eight-channel ADCs, etc.
The MYC-C437X CPU
Module integrates the AM437x processor, 512MB DDR3 SDRAM, 4GB eMMC Flash, 32KB
EEPROM, Gigabit Ethernet PHY and Power Management IC TPS65218 on board and can
be served as the controller board of your next design. It has two 0.8mm pitch
2*50-pin board-to-board expansion connectors for interconnecting with your base
board, thus providing an interface for the
base board to carry most of the I/O signals to and from the CPU module.
MYC-C437X CPU Module
The AM437x processor family consists of 4 pin-pin compatible devices (AM4376, AM4377, AM4378 and AM4379)
with various options including speed grades, packages, graphics and
peripherals. MYIR delivers the MYC-C437X with AM4377 or AM4378 processor
by default. From the image below we can see if you need EtherCAT support, the
MYC-C4377 module would be suitable; if you need 3D graphics
acceleration to support display and advanced user interfaces, the MYC-C4378 module
may fit your needs.
AM437x Devices
MYIR has
also designed two development boards for evaluating the MYC-C437X CPU Module. The
two boards are all built around the MYC-C437X CPU Module but the base board
designs are different to satisfy customers’ different requirements. The MYD-C4378 development board features versatile peripheral interfaces extended
on base board including four USB Host ports, one USB OTG, two
Gigabit Ethernet ports, two CAN, two camera interfaces, TF card slot, HDMI and
LCD interfaces but it could not support PRU-ICSS. The MYD-C4377-PRU development
board is designed especially for PRU-ICSS applications, it features one Gigabit
Ethernet port as well as two 10/100Mpbs Ethernet ports from the PRU-ICSS
subsystems and uses TI SYS/BIOS v6.45 Real-time Operating System. Besides, both of the two boards can run Linux OS and are provided
with software packages and detailed documentation sources. They are excellent
platforms for customers’ evaluation and prototype based on TI’ AM437x
solution.
