2.1 Header Information

This section describes the headers and test points for each variant of the DRV81xxx-Q1 family of devices.

DRV81008-Q1EVM, DRV81602-Q1EVM, DRV81242-Q1EVM, DRV81004-Q1EVM Headers and Test Point Information Figure 2-1 DRV81004-Q1EVM Headers and Test Point Information
Component Label Description

A

Main signal header:

  • nSCS: Serial chip select.
  • SCLK: Serial clock input.
  • SDI: Serial data in.
  • SDO: Serial data out.
  • nSLEEP: Sleep mode input.
  • IN1: Control input IN1.
  • IN0: Control input IN0.
  • 3V3: 3.3V from LDO.
  • GND: GND test point.

B

Reset/PUSH button can have two functions based on the location of the SHUNT in J6 (below RST button):

  • RST (SHUNT in position 1): pressing the button resets the MCU.
  • PUSH (SHUNT in position 3): pressing the button does a suser defined action. Currently not implemented in firmware.

C

 JTAG connector between MSP430F5338 and MSP430F5528.

D

 Connector for programming MSP430F5528 used in the eZ-FET lite debugger circuit. Only used one time by PCB manufacturer to programmed eZ-FET lite debugger MCU.

E

 3V3 LDO connector.
Note: All of the DRV81xxx-Q1EVMs have the same layout structure for A, B, C, D, and E as seen above.
