Product details
Overview
TM4C1230D5PMI7R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, and integrated peripherals including USB 2.0, CAN, 12-bit ADC (1MSPS), and multiple UART/SSI/I²C interfaces. It targets real-time industrial control, motor drive, and sensor hub applications requiring deterministic floating-point math and mixed-signal integration.
For engineers reviewing the TM4C1230D5PMI7R datasheet, TM4C1230D5PMI7R pinout, TM4C1230D5PMI7R application, or TM4C1230D5PMI7R equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C industrial temperature grade, USB device/host/OTG support, dual CAN 2.0B controllers, and hardware-accelerated cryptographic primitives in ROM.
Technical Context
The TM4C1230D5PMI7R implements a full-featured ARM Cortex-M4F core with single-precision floating-point unit (FPU), memory protection unit (MPU), and NVIC supporting up to 80 interrupts. Its system-level integration includes μDMA controller (32-channel), system clocking with PLL and multiple dividers, and power management with sleep modes down to deep-sleep with RTC wake-up.
Peripherals are tightly coupled via AHB/APB bridges: dual CAN controllers share dedicated message RAM; USB module supports device/host/OTG with internal PHY; ADC features four independent sample sequencers with hardware averaging and temperature sensor; GPIOs support masking, commit, and slew-rate control per pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, no integrated USB PHY, requires external transceiver. | Lacks native USB OTG; higher clock enables faster signal processing but increases power and thermal design complexity. | Select when higher CPU throughput is required and USB is not needed, or when leveraging ST's ecosystem and HAL libraries. |
| MSP432P401RIPZT | ARM Cortex-M4F @ 48 MHz, 2 MB flash, integrated ADC with 14-bit resolution, lower power consumption, no CAN. | No CAN interface; optimized for ultra-low-power battery-operated nodes rather than industrial real-time control. | Select for portable instrumentation or wireless sensor nodes where CAN is unnecessary and energy efficiency dominates. |
Compared with STM32F407VGT6 and MSP432P401RIPZT, the TM4C1230D5PMI7R uniquely balances industrial-grade peripherals (dual CAN, USB PHY, robust GPIO), moderate performance (80 MHz), and proven field reliability in harsh environments-making it optimal for cost-sensitive, mixed-signal embedded control where integration reduces BOM count and board area.

FAQ
What is the maximum operating frequency of the TM4C1230D5PMI7R?
The TM4C1230D5PMI7R operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with external crystal or oscillator input. This frequency is fully supported across the entire industrial temperature range (-40°C to +85°C) and enables deterministic execution of real-time control loops with sub-microsecond interrupt latency. The TM4C1230D5PMI7R maintains this speed without requiring external voltage scaling or cooling beyond standard PCB thermal design.
Does the TM4C1230D5PMI7R include an integrated USB physical layer (PHY)?
Yes, the TM4C1230D5PMI7R integrates a full-speed USB 2.0 PHY, supporting device, host, and OTG modes without external transceivers. This eliminates two external components and simplifies layout while maintaining compliance with USB 2.0 specifications. The TM4C1230D5PMI7R also includes on-chip pull-up resistors and voltage regulators for VBUS detection, enabling plug-and-play functionality in USB device applications.
How many CAN controllers does the TM4C1230D5PMI7R support?
The TM4C1230D5PMI7R integrates two independent CAN 2.0B controllers, each with dedicated message RAM and programmable bit timing. These controllers operate concurrently and support bit rates up to 1 Mbps, making the TM4C1230D5PMI7R suitable for applications requiring redundant CAN buses or multi-network architectures such as automotive body control modules and industrial automation gateways.
What is the ADC resolution and sampling rate of the TM4C1230D5PMI7R?
The TM4C1230D5PMI7R features a 12-bit successive approximation register (SAR) ADC with a maximum sampling rate of 1 million samples per second (1 MSPS). It includes four independent sample sequencers, hardware averaging (up to 64 samples), and an internal temperature sensor. This ADC configuration allows the TM4C1230D5PMI7R to perform high-fidelity analog measurements in motor current sensing, power supply monitoring, and environmental sensing applications.
Is the TM4C1230D5PMI7R pin-compatible with other Tiva C Series microcontrollers?
The TM4C1230D5PMI7R uses a 100-pin LQFP package shared with several other Tiva C Series devices, including the TM4C123GH6PM and TM4C1294NCPDT. However, pin compatibility is not guaranteed across all signals due to differences in peripheral mapping and alternate function assignments. Engineers must verify pinout alignment using TI's official "Tiva™ C Series Microcontrollers Pin Mapping" document before assuming drop-in replacement-especially for USB, CAN, and high-speed timer signals.
