Product details
Overview
TM4C1233D5PMI from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, integrated USB 2.0 OTG, 12-bit ADC (1 MSPS), and 32-channel μDMA - deployed in industrial motor control, sensor fusion gateways, and real-time embedded HMI systems.
For engineers reviewing the TM4C1233D5PMI datasheet, TM4C1233D5PMI pinout, TM4C1233D5PMI application, or TM4C1233D5PMI equivalent, key selection criteria include Cortex-M4F FPU support, USB OTG capability, hibernation module with RTC and battery-backed memory, and dual 16-bit general-purpose timers with PWM and capture functionality.
Technical Context
The TM4C1233D5PMI integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU) and NVIC supporting up to 80 interrupts. It features a dedicated hibernation module with RTC, battery-backed SRAM, and VDD3ON power mode for ultra-low-power wake-up scenarios.
Peripherals include four UARTs (one with ISO 7816 and SIR support), two I²C modules, two SPI controllers, one QEI, and a 12-bit ADC with eight sample sequencers and hardware averaging - all accessible via 32-channel μDMA with configurable arbitration and peripheral-to-memory transfer modes.

Pinout & Package
LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad; RoHS-compliant, industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Power supply inputs | Digital core (VDD), analog (VDDA), and USB PHY (VDDC) rails require independent decoupling for noise isolation and USB signal integrity. |
| GND, GNDA | Ground returns | Digital and analog ground planes must be separated and joined at single point near regulator to minimize coupling into ADC and USB paths. |

FAQ
What is the maximum operating frequency of the TM4C1233D5PMI?
The TM4C1233D5PMI operates at a maximum system clock frequency of 80 MHz, derived from its internal PLL that accepts input from the precision internal oscillator (PIOSC) or external crystal. This frequency is fully supported across all peripherals including USB, ADC, and timers, and is validated under industrial temperature conditions (–40°C to +85°C). The TM4C1233D5PMI achieves deterministic real-time response at this speed due to zero-wait-state flash execution and tightly coupled SRAM access.
Does the TM4C1233D5PMI support USB device mode without external components?
Yes, the TM4C1233D5PMI integrates a full-speed USB 2.0 OTG controller with an on-chip PHY, enabling USB device, host, or OTG operation without external transceivers. It supports standard device classes including CDC (virtual COM port), HID (keyboard/mouse), and mass storage. The USB0DP/USB0DM pins require only series 27 Ω resistors and proper 90 Ω differential trace routing - no external PHY or level-shifting ICs are needed for basic USB functionality in the TM4C1233D5PMI design.
What power modes does the TM4C1233D5PMI support for low-energy operation?
The TM4C1233D5PMI supports five low-power modes: Sleep, Deep-Sleep, Hibernate, LPWU (Low-Power Wake-Up), and VDD3ON. In Hibernate mode, current drops below 1.5 µA with RTC running and 2 KB SRAM retained using a backup battery. The hibernation module allows wake-up via RTC alarm, external GPIO, or external reset - making the TM4C1233D5PMI suitable for battery-powered sensor nodes with multi-year operational life.
How many ADC channels and sample rates does the TM4C1233D5PMI support?
The TM4C1233D5PMI features a 12-bit successive approximation register (SAR) ADC with up to 12 external input channels and 1 internal temperature sensor channel. It achieves a maximum sampling rate of 1 MSPS (mega-samples per second) in burst mode using hardware sequencers. Eight independent sample sequencers allow concurrent triggering from timers, GPIO, or software - enabling synchronized multi-channel acquisition critical for motor current and voltage monitoring in the TM4C1233D5PMI.
Is the TM4C1233D5PMI pin-compatible with other Tiva C Series MCUs?
No, the TM4C1233D5PMI is not pin-compatible with other Tiva C Series MCUs such as the TM4C123GH6PM (144-pin LQFP) or TM4C1294NCPDT (128-pin TQFP); it uses a unique 64-pin LQFP footprint. While register-level compatibility exists within the TivaWare™ software framework, hardware redesign is required for migration. Pin assignments for USB, ADC, and timers differ across packages - always verify pin mapping against the TM4C1233D5PMI-specific datasheet before layout.
