  • Page 7 PERSONAL INJURY, OR SEVERE PHYSICAL OR ENVIRONMENTAL DAMAGE. (COLLECTIVELY, "HIGH RISK APPLICATIONS") You understand and agree that your use of TQ products or devices as a component in your applications are solely at your own risk. To minimize the risks associated with your products, devices and applications, you should take appropriate operational and design related protective measures.
  • Page 8 Handling and ESD tips General handling of your TQ-products The TQ-product may only be used and serviced by certified personnel who have taken note of the information, the safety regulations in this document and all related rules and regulations. A general rule is not to touch the TQ-product during operation. This is especially important when switching on, changing jumper settings or connecting other devices without ensuring beforehand that the power supply of the system has been switched off.
  • Page 9 The electronic components of your TQ-product are sensitive to electrostatic discharge (ESD). Always wear antistatic clothing, use ESD-safe tools, packing materials etc., and operate your TQ- product in an ESD-safe environment. Especially when you switch modules on, change jumper settings, or connect other devices.
  • Page 10 The TQMa8MPxS extends the TQ-Systems GmbH product range and offers an outstanding computing performance. All essential i.MX 8M Plus signals are routed to the TQMa8MPxS SMARC pin strip. There are therefore no restrictions for customers using the TQMa8MPxS with respect to an integrated customised design. All essential components like CPU, LPDDR4, eMMC and PMIC are already integrated on the TQMa8MPxS.

  • Page 19 The memory interface of the i.MX 8M Plus supports DDR4 and LPDDR4 memory (32 bit bus) with a maximum clock rate of 2.0 GHz, which meets JEDEC LPDDR4-4000 standard. The TQMa8MPxS exclusively uses LPDDR4. A maximum of 8 Gbyte of LPDDR4 SDRAM is supported.
  • Page 20 3.2.3 Trust Secure Element The NXP Trust Secure Element SE050 (alternatively SE051) is available on the TQMa8MPxS as an assembly option and connected to the I2C1-bus. As the SMARC standard does not provide any pins for the smartcard interfaces, the signals for these interfaces in accordance with ISO14443 and ISO7816 are routed to the unused SMARC pins of the PCIe_D interface but are disconnected by default using 0R resistors.
  • Page 21 Discrete RTC PCF85063A In addition to the i.MX 8M Plus internal RTC the TQMa8MPxS provides a discrete RTC PCF85063A as an assembly option, which is controlled by the I2C1 bus. The quartz used to clock the RTC has a standard frequency tolerance of ±20 ppm @ +25 °C.
  • Page 22 JTAG The JTAG interface of the i.MX 8M Plus is made available on a connector (JST SM10B-SRSS-TB) on the TQMa8MPxS that is not fitted as standard. Its position uses an area on the upper side of the board specified in the SMARC standard. The pin assignment of the connector and the model are defined in the SMARC standard.
