FAQ
What is the maximum operating frequency of the TM4C1233C3PMIR?
The TM4C1233C3PMIR operates at a maximum system clock frequency of 80 MHz, derived from an internal PLL that accepts input from either the precision internal oscillator (PIOSC) or an external crystal. This frequency enables deterministic real-time execution of control loops and signal processing tasks within the ARM Cortex-M4F core, and all peripheral timing-including ADC sampling and UART baud rates-is synchronized to this clock domain.
Does the TM4C1233C3PMIR support USB device functionality without external components?
Yes, the TM4C1233C3PMIR includes a fully integrated USB 2.0 device controller with on-die transceiver, requiring only passive termination resistors and a USB connector. It supports USB device classes including CDC (virtual COM port), HID, and mass storage-enabling firmware updates, data export, and host communication without adding an external USB PHY or level shifter to the design.
How does the hibernation module in the TM4C1233C3PMIR reduce power consumption?
The hibernation module in the TM4C1233C3PMIR enables ultra-low-power sleep modes drawing less than 1.5 µA while retaining RTC timekeeping, wake-up event detection, and 2 KB of battery-backed SRAM. It operates independently of the main VDD supply, allowing the rest of the chip-including the Cortex-M4F core and most peripherals-to be powered down completely during idle periods in battery-powered applications.
What ADC capabilities does the TM4C1233C3PMIR provide?
The TM4C1233C3PMIR features a 12-bit successive-approximation ADC with eight input channels, capable of sampling at up to 1 MSPS. It supports hardware averaging across up to 64 samples per conversion, configurable sample sequencing, and differential input mode-making it suitable for precision measurement of temperature, voltage, current, and sensor outputs in noisy industrial environments.
Is the TM4C1233C3PMIR pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C1233C3PMIR is not pin-compatible with other Tiva C Series parts such as the TM4C123GH6PM or TM4C1294NCPDT. Its 64-pin LQFP package and specific peripheral pin mappings differ across variants-even within the same family-so PCB layout must be designed explicitly for the TM4C1233C3PMIR footprint and signal routing.
