• Manufacturer Part Number: EVB90601
• Description: EVALUATION BOARD MLX90601 IR MOD
• Manufacturer: Melexis Inc

Specifications of EVB90601

• Rohs Status: RoHS non-compliant

Connectors
The MLX90601 is connected to the EVB’s 10-pin IDC connector (CN2):
The DIN, DOUT, CLK and CS signals form the communication SPI interface of the module’s
ASIC. These signals can be used for reading from and writing to the ASIC’s internal registers
and its built-in configuration EEPROM.
The IR, TA, REL and REF signals are the module’s output signals which can have different
meaning depending on the actual configuration. These signals could be easily accessed on the
EVB, at the respective test points (KT1÷KT5).
The +5V is the module’s supply voltage, which is not permanently applied to the module. The
supply ON and OFF states are controlled by the software and are indicated by the LED D4.
The connector CN1 is an optional In-Circuit Serial Programming (ICSP) connector for
(re)programming of the microcontroller’s firmware. The connector does not exist as a physical
component. However, the pinout of the contact pads is the following:
During the optional in-circuit serial (re)programming the STOP signal must be connected to the
VSS signal.
The USB B Connector (CN3) is with a standard pinout, so it is compatible with the general-
purpose USB A to USB B computer cables that can be found in any PC store.
Jumpers Settings
The jumper JP1 (ECHO) determines the ECHO mode – NO ECHO (open) or ECHO (closed).
Principle of Operation
The MLX90601 evaluation board acts as an interface between a MLX90601 module and the PC.
It allows performing of all basic read/write operation with the module’s internal registers or
EEPROM. It also provides several test points with the important module’s output signals.
