The FPU handles single-precision math in hardware, so PID coefficients or FFT bins don't eat into the instruction budget the way they would on an M3 or M0. If your application runs a web server on the internal MAC plus a CANopen node and a 1 kHz current loop, this core keeps the margin — you won't need to offload to a separate communications processor. ## 1 MB Flash and 256 KB RAM — sizing the firmware and data buffers 1 MB of Flash holds a full TCP/IP stack, a file system, and several hundred kilobytes of application code. The 256 KB SRAM is split across multiple buses; the Ethernet controller can use a dedicated DMA channel for packet buffers without starving the CPU. If you are logging data or buffering large CAN messages, the RAM budget supports moderate ring buffers — but a design that streams video or stores a full web page for every connected device will need external SDRAM over the EBI/EMI interface. ## Package and footprint — 128-TQFP with 14x14 mm body Housed in a 128-lead TQFP with a 14x14 mm body. The package is surface-mount, suitable for standard reflow soldering. The 90 GPIO pins are distributed around all four sides.","metaTitle":"TM4C129ENCPDTT3R Tiva™ C ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash","metaDescription":"TM4C129ENCPDTT3R from Texas Instruments: 32-bit ARM Cortex-M4F MCU, 120 MHz, 1 MB Flash, 256 KB RAM, Ethernet + CAN + USB OTG, -40 to 105 °C.
