Product details

The TM4C1233H6PMIR runs an ARM Cortex-M4F core at 80 MHz with a single-precision floating-point unit. The 2 KB EEPROM on-chip saves calibration constants or boot counters without external storage.

Connectivity and I/O — USB, CAN, and serial buses

This MCU carries USB (device/host/OTG), CAN, I²C, SPI, SSI, UART, and IrDA. The USB controller supports both device and host modes. CAN is the industrial backbone; the part can sit as a sensor node on a CANopen bus. 43 general-purpose I/O in a 64-LQFP package.

Lifecycle reality — EOL, not NRND

Supply voltage spans 1.08 V to 3.63 V.

Frequently asked questions

What is the operating voltage of TM4C1233H6PMIR?

The supply voltage range is 1.08 V to 3.63 V. The core operates down to 1.08 V for low-power modes; I/O rails typically run at 3.3 V for peripheral compatibility.

Does TM4C1233H6PMIR support USB device and host modes?

Yes. The USB controller on this MCU supports device, host, and OTG modes. You can implement a USB mass-storage host or a CDC/DFU device without external PHY.

What is the package type of TM4C1233H6PMIR?

It is supplied in a 64-lead LQFP package (10x10 mm body, 0.5 mm pitch). The supplier device package is 64-LQFP (10x10).

Is there a replacement or equivalent for TM4C1233H6PMIR?

The TM4C123GH6PMI is a pin-compatible, same-package alternative from the same Tiva C series. Confirm the Flash and SRAM sizes match your firmware image before substituting.
