FAQ

What is the maximum operating frequency of the TM4C123BE6PZI7?

The TM4C123BE6PZI7 operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with an external crystal or oscillator input. This frequency applies to the ARM Cortex-M4F core, bus matrix, and all synchronous peripherals. The device maintains full specification compliance-including ADC sampling rate, USB timing, and PWM resolution-at this speed across the full -40°C to +85°C temperature range.

Does the TM4C123BE6PZI7 include an integrated USB physical layer (PHY)?

Yes, the TM4C123BE6PZI7 includes a full-speed (12 Mbps) USB 2.0 Device/Host/OTG controller with an integrated PHY. This eliminates the need for an external USB transceiver in most designs. The USB0DM and USB0DP pins connect directly to the USB connector, and the device supports standard USB descriptors, enumeration, and class drivers via the TivaWare™ USB library.

What low-power modes does the TM4C123BE6PZI7 support, and what is its lowest hibernate current?

The TM4C123BE6PZI7 supports Sleep, Deep-Sleep, and Hibernate modes. In Hibernate mode with the real-time clock (RTC) active and no external RAM retention, its typical current consumption is ≤1.6 µA at 3.3 V and 25°C. This value is specified in the SPMS366E datasheet Section 1.3.8 and validated across temperature and voltage ranges, making it suitable for multi-year battery operation in remote sensor applications.

Is the TM4C123BE6PZI7 pin-compatible with other Tiva C Series microcontrollers?

No, the TM4C123BE6PZI7 is not pin-compatible with other Tiva C Series devices such as the TM4C123GH6PGE or TM4C1294NCPDT. While they share architectural similarities and peripheral register maps, the TM4C123BE6PZI7 uses a 100-pin LQFP package with a unique pinout optimized for its specific peripheral set and power domain partitioning. Board-level replacement requires redesign.

What development tools and software support are available for the TM4C123BE6PZI7?

Texas Instruments provides full support for the TM4C123BE6PZI7 through the TivaWare™ Peripheral Driver Library, Code Composer Studio™ IDE, and LM Flash Programmer. Evaluation kits like the TM4C123G LaunchPad (EK-TM4C123GXL) are hardware-compatible and support debugging via SWD/JTAG.
