FAQ
What is the maximum operating frequency of the TM4C1233D5PMI7R?
The TM4C1233D5PMI7R operates at a maximum system clock frequency of 80 MHz, derived from an internal PLL locked to either the internal precision oscillator (PIOSC) or an external crystal. This frequency is fully supported across all operating temperature ranges (–40°C to +105°C) and supply voltages (VDD = 3.3 V ±10%). The TM4C1233D5PMI7R maintains full peripheral functionality-including USB, ADC, and PWM-at this rated speed.
Does the TM4C1233D5PMI7R include an integrated USB physical layer (PHY)?
Yes, the TM4C1233D5PMI7R integrates a full-speed USB 2.0 OTG physical layer (PHY) compliant with USB specification revision 2.0. This eliminates the need for an external transceiver and supports device, host, and OTG modes. The TM4C1233D5PMI7R's USB module includes dedicated endpoints, FIFO buffers, and descriptors managed by TivaWare USB stack-enabling plug-and-play HID, CDC, or MSC class implementations.
How much battery-backed memory does the TM4C1233D5PMI7R provide in hibernate mode?
The TM4C1233D5PMI7R provides 2 KB of battery-backed SRAM that retains data during hibernate mode when powered by VBAT. This memory is accessible only while the hibernate module is active and is preserved across full power loss. The TM4C1233D5PMI7R also includes a dedicated 32.768 kHz RTC oscillator and battery voltage monitor to manage wake events and prevent data corruption during brown-out conditions.
What analog capabilities does the TM4C1233D5PMI7R offer?
The TM4C1233D5PMI7R features a 12-bit successive-approximation ADC with up to 12 input channels, 1 MSPS sample rate, hardware averaging (up to 64 samples), and programmable trigger sources. It also includes two analog comparators with internal reference and hysteresis control. These capabilities are fully operational in run, sleep, and deep-sleep modes-enabling continuous sensor monitoring without waking the CPU.
Is the TM4C1233D5PMI7R pin-compatible with other Tiva C Series microcontrollers?
No, the TM4C1233D5PMI7R is not pin-compatible with other Tiva C Series microcontrollers such as the TM4C123GH6PM or TM4C1294NCPDT. It uses a unique 64-pin LQFP package with specific peripheral mapping optimized for USB-centric applications. Pin assignments for USB, hibernate, and analog functions differ across variants-requiring separate PCB layout for each part number.
