SOM

 

Kinetis K70/K61 System-On-Module


The Emcraft Systems K70 System-On-Module (SOM) is a compact (30 mm x 57 mm) mezzanine module that combines a 150 MHz 32-bit ARM Cortex-M4 processor core with 64 MB LPDRAM, 128 MB NAND Flash and an Ethernet PHY on a single board. The SOM interfaces to a baseboard (motherboard) using two 80-pin interface connectors.

The K61 System-On-Module is a module that is pin- and interface-compatible with the K70 SOM, except that the K61 does not provide the LCD controller interface.

Emcraft develops and maintains a Linux software distribution for the K70/K61 SOM, including Linux (uClinux) BSP (Board Support Package), U-Boot firmware and a Linux-hosted cross-development software environment.

Starter Kit

 

Kinetis Starter Kit


The K70/K61 SOM starter kit provides a low-cost ($179) hardware platform enabling development of embedded applications using the NXP K70/K61 microcontoller devices and Emcraft's K70/K61 System-On-Module (SOM). The kit includes the K70/K61 System-on-Module itself, a NXP Tower-compatible Development Baseboard (TWR-SOM-BSB), and a mini-USB cable for USB-based power and serial console.

As shipped, the kit can be used in standalone mode, without requiring any additional hardware equipment. The TWR-SOM-BSB baseboard is 90x86 mm in size and has the following main interfaces:

  • USB-UART interface connected to UART port of the K70/K61
  • 10/100 Ethernet interface and RJ-45 connector
  • JTAG interface
  • USB OTG connector for USB HS
  • MicroSD connector
  • User LEDs
  • User push button
  • Unused SOM signals available on a breadboard area
  • Other I/O interfaces of the Kinetis available on the Tower backplane connectors.

In addition to being able to operate in standalone mode, the development board included with the kit can also be used as part of the modular NXP Tower System development platform. The TWR-SOM-BSB can interoperate with all the standard peripheral modules of the NXP Tower System, such as TWR-SER, TWR-SER2, and TWR-LCD-RGB, providing the following additional interfaces:

  • Full speed OTG USB – with the NXP TWR-SER or TWR-SER2 boards
  • Color LCD with touch screen – with the TWR-LCD-RGB
  • CAN bus – with the TWR-SER or TWR-SER2 board.

Kinetis K70/K61 SOM Design Kit

 


For those customers who have successfully evaluated the Kinetis K70/K61 System-On-Module and would like to proceed with designing the SOM into embedded product, Emcraft System provides the K70/K61 SOM Design Kit.

The K70/K61 SOM Design Kit is an advanced product, separate from the K70/K61 SOM Starter Kit. The Design Kit does not include any hardware items, such as the K70/K61 System-On-Module or the SOM baseboard included in the Starter Kit.

The kit is comprised of the following materials and services:
  • The Kinetis K70/K61 System-On-Module (SOM) schematics (PDF file only). The package is provided as an advanced hardware material allowing hardware designers to understand subtle points of the SOM implementation and interface.
  • Suggested K70/K61 SOM to baseboard mapping (Excel file). Upon purchase of the kit, you will be able to send a list of I/O requirements for your application to Emcraft. Emcraft will review and return an Excel file with recommended mapping of I/O interfaces from the SOM to your custom baseboard. Here is an example of a K61 SOM interface mapping file (.pdf view of the .xls file): k61_som-io_mapping.xls.
  • 1 (one) review of your custom K70/K61 SOM baseboard schematics (SOM interface section only), with detailed comments returned over email.
