Product details
Overview
TM4C1230H6PMI7R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 256 KB flash, 32 KB SRAM, and integrated analog peripherals including 12-bit ADC (up to 1MSPS), two internal temperature sensors, and hardware-averaging capability. It supports USB 2.0 Device/Host/OTG, multiple UARTs, I²C, SSI, PWM, and GPIOs with interrupt-on-change - deployed in industrial motor control, smart sensor nodes, and USB-connected embedded gateways.
For engineers reviewing the TM4C1230H6PMI7R datasheet, TM4C1230H6PMI7R pinout, TM4C1230H6PMI7R application, or TM4C1230H6PMI7R equivalent, key selection criteria include its 80 MHz Cortex-M4F core with FPU, 12-bit ADC performance at up to 1 MSPS, USB OTG support, 105-pin LQFP package with configurable GPIOs, and industrial temperature range (–40°C to +85°C).
Technical Context
The TM4C1230H6PMI7R implements a full-featured ARM Cortex-M4F core with single-precision floating-point unit, memory protection unit (MPU), and NVIC supporting up to 80 interrupts. Its system-level integration includes a clock tree with PLL, power gating for sleep modes (Sleep, Deep Sleep, Hibernate), and ROM-based bootloader with TivaWare™ peripheral driver library support.
Peripherals are tightly coupled via the μDMA controller with 32-channel arbitration, enabling zero-CPU-overhead transfers between ADC, UART, SSI, and memory. Analog subsystem includes two independent 12-bit ADCs (ADC0 and ADC1), each with eight sample sequencers, hardware averaging (up to 64 samples), and differential input support - all synchronized to timer triggers or software events.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
TM4C1230H6PMI7R is housed in a 105-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully defined in TI's SPMS332E datasheet Section 1.4 and Table 1-1 (Pin Assignments), validated for industrial layout practices including ground plane isolation and decoupling placement near VDD/VDDA pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Power supply inputs | Digital (VDD), analog (VDDA), and core (VDDC) rails require separate 3.3 V regulation and local 100 nF + 10 µF decoupling. |
| GND, GNDA | Ground references | Digital and analog grounds must be connected at single point near regulator to minimize noise coupling into ADC paths. |
| USB0VBUS, USB0ID | USB OTG detection | Enables automatic role switching (device/host) based on VBUS presence and ID pin state - no external level-shifting needed. |
| PF0–PF4 | GPIO / NMI / SW2 | Multi-function pins supporting non-maskable interrupt, user switch input, or general I/O - configured via GPIOAFSEL register. |
| PD0–PD7 | UART0 / I²C1 / SSI2 | Shared peripheral pins - alternate function selected via GPIODEN and GPIOAFSEL; requires careful muxing during initialization. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-Point Unit (FPU) | Single-precision IEEE 754 compliant - accelerates math-intensive tasks like motor vector control or sensor fusion without software emulation overhead. |
| μDMA Controller | 32-channel, scatter-gather capable - eliminates CPU polling for ADC sampling, UART RX/TX, or SSI transfers, reducing latency and power consumption. |
| ROM Bootloader | Pre-programmed TI ROM with UART/USB/I²C firmware update interface - enables field firmware upgrades without JTAG debugger or external programmer. |
| Analog Subsystem | Dual 12-bit ADCs with hardware averaging, temperature sensor, and differential mode - delivers calibrated, low-noise measurements for closed-loop thermal or current sensing. |
| Peripheral Integration | USB OTG, CAN, PWM, QEI, and analog comparators in one die - reduces BOM count and board space versus discrete MCU + peripheral IC solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C1294NCPDT | ARM Cortex-M4F @ 120 MHz, 1 MB flash, 256 KB RAM, integrated Ethernet MAC + PHY, no CAN - larger package (144-pin BGA), higher power. | Targeted at networked HMI and gateway applications requiring Ethernet connectivity and larger code/data footprint. | Select when Ethernet interface, higher CPU throughput, or expanded memory is required - not drop-in; requires PCB redesign and driver adaptation. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, 192 KB RAM, no integrated USB PHY, no ROM bootloader - 100-pin LQFP, same industrial temp range. | Preferred where ST's ecosystem (CubeMX, HAL), Ethernet via external PHY, or higher clock speed justifies added external components. | Choose for broader toolchain support and higher clock margin; requires external USB transceiver and custom bootloader implementation. |
Compared with TM4C1230H6PMI7R, TM4C1294NCPDT adds Ethernet but removes CAN and increases footprint, while STM32F407VGT6 offers higher clock speed and memory but lacks integrated USB PHY and ROM bootloader - both require firmware and layout changes, making TM4C1230H6PMI7R optimal for cost-sensitive, USB-centric industrial control with minimal external components.

FAQ
What is the maximum operating frequency of the TM4C1230H6PMI7R?
The TM4C1230H6PMI7R operates at a maximum system clock frequency of 80 MHz, achieved via its internal PLL driven from a crystal or external clock source. This frequency applies to the Cortex-M4F core, bus matrix, and most peripherals - verified across the full industrial temperature range (–40°C to +85°C) per TI's SPMS332E datasheet Section 1.3.1 and Electrical Characteristics table.
Does the TM4C1230H6PMI7R include a USB physical layer (PHY)?
Yes, the TM4C1230H6PMI7R integrates a full-speed USB 2.0 OTG PHY, eliminating the need for an external transceiver. The USB0VBUS and USB0ID pins support automatic device/host role detection, and the ROM bootloader includes USB DFU class support - confirmed in Section 13 of the SPMS332E datasheet and TI's TivaWare documentation.
How much SRAM and flash memory does the TM4C1230H6PMI7R provide?
The TM4C1230H6PMI7R includes 32 KB of on-chip SRAM and 256 KB of flash memory with error-correcting code (ECC). Flash supports in-application programming (IAP) and sector erase; SRAM is partitioned into contiguous blocks accessible by CPU and μDMA - detailed in Section 7.2 of the SPMS332E datasheet.
Is the TM4C1230H6PMI7R pin-compatible with other Tiva C Series MCUs?
No, the TM4C1230H6PMI7R is not pin-compatible with other Tiva C Series variants such as TM4C129x or TM4C123x in different packages (e.g., 64-pin or 144-pin). Its 105-pin LQFP footprint and specific peripheral pin mappings are unique to the TM4C1230H6PM family - verified against TI's package drawings and pin multiplexing tables in SPMS332E Section 1.4.
