Key Advantages

Strong performance-per-watt with 80 MHz Cortex-M4F and FPU for fast math and control loops

Rich peripheral set reduces need for external chips (USB, CAN, multiple serial buses, PWM, QEI)

Integrated EEPROM and large Flash/SRAM simplify parameter storage and real-time tasks

Wide supply range (1.08V–3.63V) helps fit low-power and battery-backed designs

Industrial temperature rating for reliable operation in harsh environments

Mature TivaWare software ecosystem lowers development time and risk

Large I/O count (105) supports complex boards with many sensors/actuators

RoHS3 compliance for global environmental standards

Backed by Texas Instruments’ long-term ecosystem and Y-IC’s reliable distribution and support

Packaging

Shipping Type: Tape & Reel (TR) for automated SMT assembly

IC Package: 144-LQFP (Low-Profile Quad Flat Package), body size 20 x 20 mm, thin profile

Material: Molded plastic epoxy encapsulation; copper leadframe; lead-free plating (typical industry finishes such as NiPdAu or matte Sn)

Pin Configuration: 144 perimeter leads, fine-pitch (~0.5 mm typical), 105 GPIO available; dedicated pins for USB OTG, CAN, serial interfaces, ADC inputs, PWM, QEI

Mounting: Surface-mount (SMT), compatible with standard reflow soldering

Thermal Characteristics: Designed for -40°C to +85°C ambient; follow TI reflow and thermal guidelines; board layout and airflow significantly affect junction temperature

Electrical Properties (key): 1.08V–3.63V supply, 80 MHz operation, 12-bit ADC, USB and CAN transceivers interface via dedicated pins; observe TI datasheet for I/O voltage levels, drive strength, ESD ratings, and timing

Handling: Moisture sensitivity and reflow profile per TI specifications; use dry-pack and proper baking if required

Lifecycle

Status: Active and widely used; not nearing discontinuation based on current industry information

Equivalent / Alternative Models:

- TM4C123GH6PGEI (same device; different packing option, tray)

- TM4C123GH6PGE (commercial temperature variant; confirm temperature grade)

- TM4C123GH6PZ (100-pin LQFP; similar features, fewer pins; not pin-compatible)

- TM4C123GH6PM (64-pin LQFP; similar core; not pin-compatible)

- TM4C1294NCPDT (higher-performance Tiva C with Ethernet; different pinout; not pin-compatible)

- Legacy Stellaris LM4F family devices may be functionally similar but are superseded by TM4C; confirm availability and compatibility

Note: Pin compatibility and exact peripheral mapping vary by package and family. Validate against your PCB and firmware. If you need drop-in or form-fit alternatives, contact our sales team via the Y-IC website for tailored recommendations.
