FAQ

What is the maximum operating frequency of the TM4C123GH6PGET7?

The TM4C123GH6PGET7 operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL with support for multiple clock sources including internal RC oscillator, external crystal (up to 25 MHz), or external clock input. This frequency is sustained across the full industrial temperature range (–40°C to +105°C) and supply voltage (2.95 V to 3.63 V), ensuring deterministic real-time performance in demanding environments.

Does the TM4C123GH6PGET7 support USB device and host modes?

Yes, the TM4C123GH6PGET7 integrates a full-speed USB 2.0 On-The-Go (OTG) controller with a physical layer (PHY), enabling both device and host modes without external transceivers. Mode selection is controlled by the USB0ID pin state, and VBUS sensing (via USB0VBUS) allows safe enumeration and power negotiation - essential for field-serviceable devices and diagnostic tools using the TM4C123GH6PGET7.

How much SRAM and flash memory does the TM4C123GH6PGET7 include?

The TM4C123GH6PGET7 includes 32 KB of on-chip SRAM and 256 KB of on-chip flash memory. The SRAM is partitioned into general-purpose RAM and a dedicated 2 KB hibernation RAM that retains data during deep-sleep states. Flash memory supports in-application programming (IAP), wear leveling for EEPROM emulation, and secure locking to prevent unauthorized firmware extraction - all managed natively by the TM4C123GH6PGET7's ROM bootloader.

What analog peripherals are integrated into the TM4C123GH6PGET7?

The TM4C123GH6PGET7 integrates a 12-bit, 1 MSPS analog-to-digital converter (ADC) with 12 input channels and four independent sample sequencers, an internal temperature sensor, two analog comparators with programmable hysteresis, and a 12-bit, 1 MSPS digital-to-analog converter (DAC) on one channel. These peripherals operate independently of the CPU via μDMA triggers, enabling continuous analog monitoring without interrupt overhead - a key capability in motor control and sensor fusion applications using the TM4C123GH6PGET7.

Is the TM4C123GH6PGET7 qualified for industrial temperature operation?

Yes, the TM4C123GH6PGET7 is rated for operation from –40°C to +105°C ambient temperature and is qualified per industrial-grade reliability standards. Its LQFP-144 package uses lead-free, RoHS-compliant materials and is tested for thermal cycling, moisture sensitivity level (MSL 3), and long-term parametric stability - making it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and automotive under-hood auxiliary systems where the TM4C123GH6PGET7 serves as the primary controller.
