What are the key features of DP83848TSQ/NOPB?

  • IEEE 802.3u compliant 10/100 Mbps Fast Ethernet PHY with auto-negotiation for seamless network speed switching without host CPU intervention
  • Single 3.3 V supply operation with integrated termination resistors reducing external component count and simplifying PCB design for embedded Ethernet nodes
  • 40-pin LLP (QFN) package with exposed thermal pad enabling efficient heat dissipation in compact industrial and embedded networking boards

What is DP83848TSQ/NOPB used for?

The DP83848TSQ/NOPB is designed for embedded Ethernet connectivity in industrial automation controllers, medical devices, and smart energy meters requiring IEEE 802.3u compliant 10/100 Mbps networking. Its single 3.3 V supply and compact 40-pin LLP package make it ideal for space-constrained SoC-based designs needing an MII or RMII interface to a host processor. It also suits home automation gateways, point-of-sale terminals, and network cameras where low-cost reliable Fast Ethernet connectivity is required.

Frequently Asked Questions

What Ethernet data rate does the DP83848TSQ/NOPB support, and does it auto-negotiate speed?

The DP83848TSQ/NOPB supports both 10 Mbps and 100 Mbps Ethernet data rates per IEEE 802.3u, with built-in auto-negotiation that automatically selects the highest mutually supported speed between the PHY and the connected switch or network device, eliminating manual speed configuration in embedded system firmware.

What host interface does the DP83848TSQ/NOPB present to a microcontroller or SoC?

The DP83848TSQ/NOPB provides a standard MII interface operating at 25 MHz for 100 Mbps and 2.5 MHz for 10 Mbps, as well as an RMII mode running at 50 MHz single clock, allowing it to connect directly to the Ethernet MAC peripheral integrated in processors such as ARM Cortex-M and MIPS SoCs without additional glue logic.

What supply voltage does the DP83848TSQ/NOPB require, and is an additional 1.8 V rail needed?

The DP83848TSQ/NOPB operates from a single 3.3 V supply for both I/O and core functions, with internal voltage regulation generating any lower internal bias required, so no separate 1.8 V supply rail is needed, which simplifies the power supply design compared to PHYs that require dual-rail 3.3 V and 1.8 V inputs.

How does the 40-pin LLP package of the DP83848TSQ/NOPB compare to a larger LQFP48 in terms of PCB area?

The 40-pin LLP (QFN) package measures approximately 6 mm × 6 mm with a 0.5 mm pitch, occupying about 36 mm² versus roughly 122 mm² for a standard 48-pin LQFP, making the LLP package approximately 3× smaller and enabling tighter integration on constrained embedded boards.

Is the DP83848TSQ/NOPB suitable for industrial temperature range applications?

The DP83848TSQ is rated for an extended industrial temperature range of -40°C to +85°C, and the NOPB suffix confirms RoHS-compliant lead-free construction with JESD-609 e3 halogen-free qualification, making it appropriate for industrial Ethernet nodes in factory automation, process control, and building management systems.
