FAQ

What is the maximum operating frequency of the TM4C1230E6PM?

The TM4C1230E6PM operates at a maximum CPU clock frequency of 80 MHz, achieved via its on-chip PLL driven by either the internal precision oscillator (PIOSC) or an external crystal. This frequency is fully supported across the entire industrial temperature range (-40°C to +105°C), and all peripherals-including USB, ADC, and PWM-are rated for synchronous operation at this speed. The TM4C1230E6PM datasheet confirms timing specifications are guaranteed at 80 MHz under worst-case voltage and temperature conditions.

Does the TM4C1230E6PM include an integrated USB physical layer (PHY)?

Yes, the TM4C1230E6PM integrates a full-speed USB 2.0 PHY compliant with the USB specification, supporting device, host, and OTG modes without requiring external transceivers. This PHY connects directly to the USB0DP and USB0DM pins and is powered from the VDD3P3ANA rail. The integrated PHY enables plug-and-play USB functionality in designs such as firmware updaters, HID devices, and CDC-based communication interfaces-all implemented within the TM4C1230E6PM itself.

How much flash and SRAM memory does the TM4C1230E6PM provide?

The TM4C1230E6PM provides 256 KB of on-chip flash memory for program storage and 32 KB of general-purpose SRAM for runtime data. Flash memory supports in-application programming (IAP) via the ROM bootloader, and both memory blocks are accessible via the AHB bus for zero-wait-state operation at 80 MHz. The TM4C1230E6PM also includes 2 KB of EEPROM emulated in flash and a 4 KB boot ROM containing driver libraries and USB/UART firmware update routines.

What ADC capabilities does the TM4C1230E6PM offer?

The TM4C1230E6PM features a 12-bit successive approximation register (SAR) ADC with up to 12 input channels, capable of 1 million samples per second (1 MSPS) in burst mode. It supports four independent sample sequencers, hardware averaging (up to 64 samples), differential input mode, and an internal temperature sensor. All ADC functions-including trigger sources, sequencing, and digital comparator interrupts-are fully configurable in the TM4C1230E6PM without external support circuitry.

Is the TM4C1230E6PM qualified for industrial temperature operation?

Yes, the TM4C1230E6PM is explicitly rated for industrial temperature operation from -40°C to +105°C, as confirmed in Section 1.3.7 ("Packaging and Temperature") of the official Texas Instruments datasheet (SPMS331E). This qualification applies to all electrical specifications-including CPU speed, ADC accuracy, USB timing, and GPIO drive strength-making the TM4C1230E6PM suitable for deployment in harsh environments such as factory floors, outdoor energy infrastructure, and under-hood automotive subsystems.
