Texas Instruments TM4C1233D5PZI

Overview

TM4C1233D5PZI from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 device controller, and 12-bit ADC with 12 channels - deployed in industrial motor control, sensor fusion gateways, and programmable logic controllers.

For engineers reviewing the TM4C1233D5PZI datasheet, TM4C1233D5PZI pinout, TM4C1233D5PZI application, or TM4C1233D5PZI equivalent, key selection criteria include USB device stack support, hibernation module with RTC and battery-backed memory, deterministic real-time interrupt latency (<12 cycles), and dual-CAN 2.0B interface capability.

Technical Context

The TM4C1233D5PZI integrates a single-core ARM Cortex-M4F CPU with hardware floating-point unit (FPU), supporting IEEE 754 single-precision arithmetic and Thumb-2 instruction set. It features a 32-bit bus matrix with separate AHB/APB bridges for concurrent peripheral access and deterministic memory arbitration.

System-level integration includes a hibernation module with dedicated 32.768 kHz RTC oscillator, battery-backed 2 KB SRAM, and VBAT monitoring; plus a μDMA controller with 32-channel support, configurable priority, and peripheral-to-memory transfer without CPU intervention.

FAQ

What is the maximum operating frequency of the TM4C1233D5PZI?

The TM4C1233D5PZI operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL with support for multiple clock sources including external crystals, internal oscillators, and USB SOF synchronization. This frequency is fully supported across all operating conditions specified in the datasheet, including the full –40°C to +105°C temperature range.

Does the TM4C1233D5PZI include an integrated USB physical layer?

Yes, the TM4C1233D5PZI integrates a full-speed USB 2.0 physical layer (PHY) with on-die termination and slew-rate control. This eliminates the need for an external USB transceiver, reduces BOM count, and ensures USB-IF compliance without requiring external passive components on the D+/D– lines.

What low-power capabilities does the TM4C1233D5PZI support?

The TM4C1233D5PZI supports six low-power modes, including Hibernate mode with <1 µA typical current draw. Its hibernation module includes a dedicated 32.768 kHz RTC oscillator, battery-backed 2 KB SRAM, and VBAT monitoring - enabling autonomous wake-up on timer expiry, external pin assertion, or RTC alarm without main power.

How many CAN interfaces does the TM4C1233D5PZI provide?

The TM4C1233D5PZI integrates two independent CAN 2.0B controllers, each with dedicated message RAM, filtering logic, and transmit/receive FIFOs. Both controllers support bit rates up to 1 Mbps and are electrically isolated from the core domain, allowing concurrent CANopen and J1939 protocol stacks.

Is the TM4C1233D5PZI pin-compatible with other Tiva C Series MCUs?

No, the TM4C1233D5PZI is not pin-compatible with other Tiva C Series MCUs such as the TM4C129x family or TM4C123GH6PM. Its LQFP-100 package has a unique pin assignment optimized for USB, dual CAN, and hibernation functionality - migration requires PCB redesign and firmware adaptation.
