FAQ

What is the maximum operating frequency of the TM4C1233D5PMIR?

The TM4C1233D5PMIR operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with either an external crystal (4–25 MHz) or internal precision oscillator. This frequency is fully supported across all operating temperature ranges (–40°C to +105°C) and supply voltages (3.0 V to 3.6 V), enabling deterministic real-time execution for motor control and communication stacks.

Does the TM4C1233D5PMIR include an integrated USB physical layer?

Yes, the TM4C1233D5PMIR includes a full-speed USB 2.0 OTG controller with an integrated PHY, supporting both host and device modes without requiring external transceivers. This integration reduces bill-of-materials cost and PCB area, and is validated per USB-IF compliance testing for enumeration and data transfer reliability across Windows, Linux, and custom host environments.

What low-power modes are supported by the TM4C1233D5PMIR?

The TM4C1233D5PMIR supports six low-power modes: Sleep, Deep-Sleep, Hibernate, and three variants of Deep-Sleep with varying peripheral retention. In Hibernate mode, it draws just 1.7 µA while retaining RTC operation, 2 KB of hibernation RAM, and wake capability via external pins or RTC alarm - making it ideal for battery-backed remote sensors and energy-harvesting systems.

How many CAN controllers does the TM4C1233D5PMIR integrate?

The TM4C1233D5PMIR integrates two independent CAN 2.0B controllers, each with dedicated message RAM (up to 64 messages), programmable bit timing, and hardware acceptance filtering. These controllers operate concurrently and support bit rates up to 1 Mbps, enabling dual-bus architectures for redundancy or functional separation in industrial automation and vehicle subsystems.

Is the TM4C1233D5PMIR pin-compatible with other Tiva C Series microcontrollers?

No, the TM4C1233D5PMIR is not pin-compatible with other Tiva C Series devices such as the TM4C123GH6PMIR or TM4C1294NCPDT; it uses a unique 64-pin LQFP footprint optimized for USB/CAN-focused applications. Pin assignments differ significantly - especially for USB, CAN, and Ethernet signals - requiring dedicated PCB layout and cannot be substituted without hardware revision.
