MAXQ622 Evaluation Kit

General Description

The MAXQ622 evaluation kit (EV kit) provides a

proven platform for conveniently evaluating the

capabilities of the MAXQ622 low-power, 16-bit, RISC

microcontroller with USB interface targeted for battery-

powered applications. The EV kit includes the MAXQ622

EV kit board, which contains infrared (IR) transmit

and receive devices, a USB Mini-B interface, headers

providing access to the processor’s I/O port pins, a

single 5V power-supply input, and a bank of eight

pushbutton switches for user input. With the included

software, USB-to-JTAG adapter, and a USB cable

connected to a personal computer, the EV kit provides

a complete, functional system ideal for developing and

debugging applications as well as evaluating the overall

capabilities of the MAXQ622 RISC processor.

MAXQ622 EV Kit Board Functional Layout Detailed Description of Hardware This EV kit must be used with the following documents: • MAXQ612/MAXQ622 IC Data Sheet • MAXQ612/MAXQ622 User’s Guide • MAXQ622 EV Kit Data Sheet (this document) These documents are available online at: www.maximintegrated.com/MAXQ622 4 The MAXQ622 EV kit is fully defined in the schematic (Figure 3). A short description of the major sections and functions of the board follows.

MAXQ622 Evaluation Kit Evaluates: MAXQ622 If the USB-to-JTAG interface adapter is being used, the EV kit is supplied by the USB 5V power, which is available to the USB-to-JTAG adapter. Power can also be supplied to the MAXQ622 EV kit through the MAXQ622 microcontroller’s USB interface. When a powered USB cable is plugged into CN1, connecting jumper JH10 allows the on-board +3.3V regulator to be powered directly from the USB supply.

MAXQ622 Evaluation Kit Evaluates: MAXQ622 User Input Pushbuttons The MAXQ622 EV kit provides eight momentary contact switches intended for user input. Each switch is connected to a separate port pin on the MAXQ622’s port 1 (P1.7 to P1.0) as shown in Table 3. The other side of each switch is connected to ground. Therefore, by using the weak pullup capability of the port pins, switch closure can be detected by reading a low on the normally high corresponding port pin. Table 3.
