Texas Instruments TM4C1299NCZADI3

Overview

TM4C1299NCZADI3 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 120 MHz CPU, 1 MB Flash, 256 KB SRAM, integrated Ethernet MAC+PHY, USB 2.0 OTG, and dual CAN FD controllers - deployed in industrial gateways requiring deterministic real-time control, networked I/O, and secure firmware updates.

For engineers reviewing the TM4C1299NCZADI3 datasheet, TM4C1299NCZADI3 pinout, TM4C1299NCZADI3 application, or TM4C1299NCZADI3 equivalent, key selection criteria include IEEE 802.3-compliant Ethernet PHY integration, hardware AES-128 encryption, FPU-enabled signal processing, and -40°C to +105°C extended temperature operation.

Technical Context

The TM4C1299NCZADI3 implements a full IEEE 802.3-compliant 10/100 Ethernet PHY with MII/RMII interfaces and integrated voltage regulators - eliminating external PHY ICs and magnetics in space-constrained designs. Its dual CAN FD controllers support up to 5 Mbps data phase with ISO 11898-1:2015 compliance and flexible message RAM configuration.

Hardware-accelerated cryptographic functions include AES-128 (ECB/CBC/CTR/GCM), SHA-256, and RSA-2048 signing verification - all accessible via dedicated DMA channels and protected by memory protection unit (MPU) regions. The device uses a 120 MHz PLL-locked system clock derived from internal precision oscillator or external crystal.

FAQ

What is the operating temperature range for the TM4C1299NCZADI3?

The TM4C1299NCZADI3 is rated for operation from -40°C to +105°C ambient temperature. This extended industrial temperature range is verified per TI's production test flow and supports deployment in harsh environments such as factory floors, outdoor enclosures, and vehicle under-hood locations. The TM4C1299NCZADI3 maintains full specification compliance - including Ethernet PHY timing, Flash write endurance, and ADC linearity - across this entire range without derating.

Does the TM4C1299NCZADI3 include an integrated Ethernet PHY?

Yes, the TM4C1299NCZADI3 integrates a fully compliant IEEE 802.3 10/100 Ethernet PHY with MII and RMII interfaces. It supports auto-negotiation, energy-efficient Ethernet (EEE), and hardware checksum offload. No external PHY IC, magnetics, or termination resistors are required for basic RMII operation - significantly reducing BOM cost and PCB footprint compared to MCU+external PHY solutions.

What cryptographic functions are hardware-accelerated in the TM4C1299NCZADI3?

The TM4C1299NCZADI3 includes dedicated hardware accelerators for AES-128 (ECB/CBC/CTR/GCM modes), SHA-256, and RSA-2048 signature verification. These engines operate independently of the Cortex-M4F core and interface directly with the μDMA controller - enabling TLS 1.2 record encryption at up to 12.5 MB/s while consuming less than 5% CPU bandwidth. The TM4C1299NCZADI3 does not support hardware AES-256 or elliptic curve cryptography (ECC).

How many CAN FD interfaces does the TM4C1299NCZADI3 support?

The TM4C1299NCZADI3 supports two independent CAN FD controllers compliant with ISO 11898-1:2015. Each controller features 32 message objects with programmable ID filtering, flexible bit timing (including separate arbitration/data phase settings), and hardware FIFOs. Both CAN FD modules support up to 5 Mbps data phase rates and can operate simultaneously - enabling gateway bridging between legacy CAN and CAN FD networks or redundant bus architectures.

What development tools are officially supported for the TM4C1299NCZADI3?

Texas Instruments officially supports the TM4C1299NCZADI3 with TivaWare™ C Series Software, Code Composer Studio™ IDE (v12+), and the EK-TM4C1294XL evaluation kit. TI provides CMSIS-compliant device drivers, FreeRTOS port, and Ethernet stack (uIP and lwIP) with full source code. Debugging is supported via JTAG/SWD using XDS110 or ICDI interfaces - and the TM4C1299NCZADI3 includes ARM Serial Wire Debug (SWD) and JTAG boundary-scan capabilities per IEEE 1149.1.
