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: do not 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.
BRIEF DESCRIPTION BRIEF DESCRIPTION The STK-MBa53 is designed to be used in combination with the TQ module TQMa53, which is based on the Freescale ARM-CPU MCIMX53 (i.MX53). Together with the module TQMa53 the STK-MBa53 provides all basic functions and interfaces.
The technical characteristics of the TQMa53 are to be taken from the User's a Manual The available signals are routed over the two 120-pin module connectors X1 and X2 to the STK-MBa53. Table 7 and Table 8 show the pins assignment of the connectors as well as signal names and directions seen from the TQMa53.
Illustration 3: Block diagram I C buses Both I C buses of the TQMa53 are used on the STK-MBa53 (I C2 and I C3). Table 9 and Table 10 show the internally used device addresses. The I C buses I C2 and I C3 are also routed on the headers X18 and X19.
Attention: destruction or malfunction Attention: destruction or malfunction There are no pull-ups for the I C3 bus on the STK-MBa53. On a carrier board these pull-ups have to be provided, however. The pin headers X18 and X19 as well as the DVI receptacle X5 are described in sections 4.2.13, or 4.2.7.
GPIOs are required for some communication interfaces (e.g., DVI) to read status signals, or to display control signals. A GPIO port expander PCA9554, which is connected to I C bus I C2, is provided on the STK-MBa53 for this purpose.
Illustration 5: Block diagram temperature sensor As with the TQMa53 a temperature sensor is also provided on the STK-MBa53. The same sensor as on the TQMa53 is used. It is connected to the same I C bus (I C2). The sensor on the STK-MBa53 has a different I C address, (see Table 9 section 4.1.2, I C address mapping).
Page 16 4.1.6 Power and Reset Illustration 9: Block diagram Power and Reset There are several different possibilities to trigger a reset on the STK-MBa53, which are shown in the following table. Table 17: Resets on the TQMa53 Reset-Signal Description Trigger •...
Block diagram power supply The STK-MBa53 is supplied at X8, or optionally at X21, with 12 V and generates 3.3 V and 5 V internally. To supply external components these three internal supply voltages are additionally routed on pin header X20 (Power-Out).
4.2.3 USB 2.0 Hi-Speed OTG The USB-OTG interface of the TQMa53 is provided on the STK-MBa53. The OTG compatibility is achieved by a 5-pin Micro-AB receptacle. The ID signal is directly routed to the CPU. USB 2.0 has been implemented, which works in the Hi-Speed, Full-Speed or Low- Speed mode.
Block diagram CAN1/CAN2 Both CAN interfaces of the STK-MBa53 are directly connected to the CAN ports of the TQMa53. They are available at the 3-pin plug connectors X3 and X4. Both interfaces are galvanically separated from the rest of the circuitry. The two CAN interfaces are, however, not galvanically separated from each other.
• By fixed wiring using the config pins On the STK-MBa53 the configuration by I C is used by default. The display interface can also be configured using configuration resistors as a placement option. Detailed information concerning the component placement options is to be taken from the circuit diagram.
(amplified) headphone output. The headphone output is, however, not available on the STK-MBa53 by default. It can be enabled at X13 by placement option. The necessary configurations are shown in Table 52.
4.2.13 Pin headers To connect extension cards to the STK-MBa53 all unused and some other selected signals are routed to pin headers X18, X19 and X20. All pin headers have 60 pins with a 2.54 mm pitch. The close placement of the headers makes it easy to plug on self-developed boards.
