TM4C1290NCPDTI3R - Tiva C Series 120MHz ARM Cortex-M4F MCU, 1MB Flash | TI
The Texas Instruments TM4C1290NCPDTI3R is a high-performance 32-bit ARM Cortex-M4F microcontroller from TI's Tiva C Series, featuring a 120MHz core with FPU, 1MB Flash, and 256KB SRAM, housed in a 128-pin TQFP (14x14 mm) package. The device integrates extensive connectivity including Ethernet MAC+PHY, USB 2.0, CAN, UART, I2C, and SPI, making it well suited for connected industrial and IoT embedded designs.
What is an ARM Cortex-M4F microcontroller? An ARM Cortex-M4F microcontroller is a 32-bit MCU based on the ARM Cortex-M4 processor core with single-precision floating-point unit (FPU), DSP extensions, and a Nested Vectored Interrupt Controller (NVIC). The M4F sits in the Cortex-M family hierarchy above Cortex-M0/M0+ (low-power 8/16-bit class performance) and Cortex-M3 (basic 32-bit), delivering deterministic real-time performance with DSP-class signal processing capability. Microcontrollers occupy the embedded computing tier below microprocessors (MPUs) in the system-on-chip taxonomy, integrating CPU, memory, peripherals, and often connectivity IP into one package.
Key features of the TM4C1290NCPDTI3R include: integrated 10/100 Ethernet MAC and PHY, USB 2.0 full-speed host/device/OTG, two CAN 2.0B controllers, eight UARTs, ten I2C, four SSI/SPI, a 12-bit 2MSPS ADC with up to 24 analog inputs, and a hibernation module with RTC. The on-chip memory of 1MB Flash and 256KB single-cycle SRAM supports data-logging buffers, TCP/IP stacks (such as lwIP or TI's own NDK), and real-time control loops without external memory in many designs. The 16-bit CRC engine and AES/DES/SHA crypto accelerators (via the TivaWare library) are commonly leveraged for secured connectivity.
Typical applications include industrial Ethernet gateways, PLC modules, networked sensors, building automation controllers, USB host peripherals (printers, scanners, POS terminals), automotive telematics, smart energy and smart grid endpoints, and SCADA remote terminal units (RTUs). The wide 3.3V I/O and integrated PHY reduce external BOM for cost-sensitive connected designs.
When designing with this MCU, pay close attention to the TQFP-128 thermal performance at high CPU loading. Validate that the hibernation current budget meets battery-backed RTC requirements, and ensure PCB layout keeps the Ethernet differential pairs length-matched within datasheet tolerances.
