NXP Semiconductors OM13257,598

Overview

OM13257,598 from NXP Semiconductors is a temperature sensor daughter card designed to interface directly with the OM13320 Fm+ Development Kit for rapid evaluation of NXP's I²C-compatible temperature sensors-including LM75ADP, SE95DP, PCT2075DP (TSSOP8), LM75BGD (XSON8), and PCT2202UK (WLCSP6). It supports dual supply voltages (3.3 V or 5 V), configurable I²C slave address via jumpers JP10–JP12, and provides LED indicators for power and interrupt status.

For engineers reviewing the OM13257,598 datasheet, OM13257,598 pinout, OM13257,598 application, or OM13257,598 equivalent, this board enables hands-on validation of thermal sensing in embedded control systems, industrial monitoring nodes, and I²C bus protocol debugging-especially where flexible voltage rail selection, jumper-based address assignment, and multi-package footprint compatibility are required.

Technical Context

The OM13257,598 functions as a hardware adapter platform-not an IC-and relies on user-soldered temperature sensor ICs (e.g., LM75ADP, SE95DP) to perform actual sensing. Its electrical interface is strictly I²C-based, with dedicated SCL/SDA routing from both Bus 1 and Bus 2 of the OM13320 host board via JP3/JR4 selection, plus direct SCL/SDA access through CN4 for external analyzers like Total Phase Aardvark or Beagle tools.

Power delivery is decoupled: JP1 selects between 5 V from CN4 or CN5; JP2 routes either 3.3 V or 5 V to pin 8 of the DUT. The board includes no onboard regulation-it passes through selected rails-and features scope ground loops and INT signal routing to an LED for real-time event visibility during firmware bring-up.

FAQ

What is the primary function of the OM13257,598?

The OM13257,598 is a temperature sensor daughter card that serves as a plug-in evaluation platform-not an active sensing device. It provides mechanical and electrical interface support for user-soldered NXP temperature sensors (e.g., LM75ADP, SE95DP) on the OM13320 Fm+ Development Kit. Its role is to enable rapid prototyping, I²C address testing, voltage rail validation, and interrupt behavior observation during firmware development. OM13257,598 itself contains no silicon die or sensing capability.

Which temperature sensor ICs are compatible with OM13257,598?

The OM13257,598 supports multiple NXP temperature sensors across three package types: TSSOP8 (LM75ADP, LM75BDP, SE95DP, PCT2075DP), XSON8/HWSON8 (LM75BGD, LM75BTP, PCT2075TP), and WLCSP6 (PCT2202UK). Compatibility is confirmed by footprint alignment and pin mapping per UM10757 Table 1. Each device must be manually soldered onto the corresponding footprint before use. OM13257,598 does not include any pre-mounted sensor IC.

How do I configure the I²C address for a sensor mounted on OM13257,598?

The OM13257,598 uses jumpers JP10, JP11, and JP12 to set logic levels on pins 5, 6, and 7 of the mounted temperature sensor-matching the address configuration bits defined in each device's datasheet (e.g., LM75ADP uses A2–A0 on pins 5–7). Pin 1 of each jumper connects to GND; pin 3 connects to VDD (selected via JP2). No soldering or firmware changes are needed-address is purely hardware-defined. OM13257,598 provides no automatic address detection or software override.

Can OM13257,598 operate independently without the OM13320 Fm+ Development Kit?

No-OM13257,598 lacks power regulation, microcontroller, clock source, or USB interface and cannot function autonomously. It requires physical and electrical connection to the OM13320 Fm+ Development Kit via CN5 (14-pin shrouded male connector) for power, I²C communication, and reset signaling. While CN4 allows connection to external I²C analyzers (e.g., Total Phase Beagle), host-level control and firmware interaction still depend on the OM13320 platform. OM13257,598 is not a standalone evaluation board.

Does OM13257,598 support both 3.3 V and 5 V operation for the mounted sensor?

Yes-OM13257,598 supports either 3.3 V or 5 V supply to the mounted temperature sensor via independent jumper settings: JP1 selects input source (CN4 or CN5), and JP2 routes the selected rail to pin 8 (VDD) of the DUT. This dual-voltage flexibility allows validation of sensor behavior across common embedded system rails without hardware modification. OM13257,598 delivers only the selected rail-no level shifting or voltage translation is provided.
