Product details

What this part is

It runs at 80 MHz and carries 512 KB of Flash plus 64 KB of RAM.

An integrated Ethernet MAC and PHY anchors the networking side, supported by I²C, SPI, SSI, UART, IrDA, LIN, and Microwire serial interfaces. The peripheral set includes PWM, DMA, a watchdog timer, brown-out reset, and power-on reset — enough to handle a motor drive or a remote sensor gateway without external glue logic.

Housed in a 108-ball LFBGA (10x10 mm body), the part is surface-mount only.

Texas Instruments has marked this part as obsolete. No official replacement part number has been published for this exact order code.
