Key Features

10 Mbps and 100 Mbps Ethernet PHY operation per IEEE 802.3

Single port design with one transmit and one receive channel

MAC interface options MII and RMII for flexible MCU or SoC connection

Auto negotiation for speed and duplex

Auto MDI MDIX for automatic crossover on twisted pair

Link status and activity indications LED support via pins

Loopback and test modes for production and field diagnostics

Power down and isolate modes to reduce power when idle

25 MHz crystal or external oscillator support RMII uses 50 MHz reference

ESD and EMI conscious design see datasheet for limits

RoHS3 compliant and lead free green packaging

Key Advantages

Proven TI DP83848 family interoperability across a wide range of MACs

Wide industrial temperature span for harsh environments

Low power operation at 3.3 V simplifies power design

Compact 6 x 6 mm WQFN saves board area compared with LQFP options

Exposed pad improves thermal performance and ground integrity

Long lifecycle family with broad ecosystem and design resources

Packaging

Package type 40 WQFN with exposed thermal pad

Body size about 6 mm x 6 mm nominal height per datasheet

Material plastic mold compound with copper leadframe lead free per RoHS3

Pin configuration 40 signal pins plus center pad pins include twisted pair differential pairs MAC interface MII RMII signals oscillator pins XI XO management MDC MDIO strap and LED pins analog and digital 3.3 V supplies and grounds

Mounting surface mount only reflow compatible observe moisture sensitivity level per datasheet and JEDEC J STD 020

Thermal characteristics center pad must be soldered to a grounded thermal land with vias to inner ground planes for best thermal and EMI performance junction temperature rating aligns with minus 40°C to 85°C ambient when properly cooled

Electrical properties supply range 3.0 V to 3.6 V typical 3.3 V logic interface voltage levels per TI spec supports 25 MHz crystal or clock input RMII 50 MHz reference refer to datasheet for current consumption signal levels and timing

Shipping format Tape and Reel TR for automated assembly

Lifecycle

Status active and in production by Texas Instruments as of the latest public information not at end of life

Same family and package variants DP83848 family offers multiple package options if you need a specific footprint or function check DP83848I and other suffixes

TI newer low power 10 100 PHY alternatives DP83822I DP83825I DP83826E features and pins differ these are not pin to pin drop ins for WQFN verify fit and features

Cross brand functional alternatives examples Microchip KSZ8081 KSZ8041 and LAN8720A RMII only Realtek RTL8201 and others not pin compatible different features and packages
