Product details
Overview
TM4C1230H6PMI 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 UARTs, two I²C, two SSI, and USB 2.0 device support. It targets real-time industrial control, motor drive feedback, and sensor hub applications requiring deterministic floating-point math and on-chip connectivity.
For engineers reviewing the TM4C1230H6PMI datasheet, TM4C1230H6PMI pinout, TM4C1230H6PMI application, or TM4C1230H6PMI equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C industrial temperature range, USB device capability, integrated ROM bootloader, and hardware FPU for signal processing workloads.
Technical Context
The TM4C1230H6PMI integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU) compliant with IEEE 754-2008, supporting both single-precision arithmetic and DSP instructions. Its memory subsystem includes 256 KB on-chip flash with error correction (ECC), 32 KB SRAM, and 8 KB ROM containing TivaWare™ boot and driver libraries.
Peripherals are tightly coupled via the AHB/APB bus matrix: dual 12-bit ADCs with up to 12 sample sequencers and hardware averaging, USB 2.0 device controller with integrated PHY, and programmable GPIOs with slew-rate control and configurable pull-up/down. Clock management supports multiple PLL configurations with internal precision oscillator (PIOSC) and external crystal options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4F @ 80 MHz - enables real-time deterministic execution with hardware FPU for sensor fusion or motor control math. |
| Flash / SRAM | 256 KB flash (with ECC) / 32 KB SRAM - sufficient for standalone firmware with USB stack and control algorithms without external memory. |
| ADC | 12-bit, 1 MSPS, 12-channel - supports high-speed analog acquisition for closed-loop current/voltage sensing in power electronics. |
| USB Interface | USB 2.0 full-speed device with integrated PHY - eliminates need for external transceiver; supports HID, CDC, and mass storage class implementations. |
| Package & Temp | 100-pin LQFP, -40°C to +85°C - compatible with standard PCB assembly processes and suitable for industrial ambient environments. |
| Debug Interface | JTAG + SWD - enables full-cycle development with breakpoints, watchpoints, and real-time trace via TI XDS110 or compatible debug probes. |

Pinout & Package
TM4C1230H6PMI is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments follow TI's standard Tiva C Series pin mapping for consistent layout reuse across the TM4C123x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VDDA / VDDC | Power supply rails | VDD (digital core), VDDA (analog), VDDC (USB PHY) - require separate filtering; VDDA must be ≥ VDD for ADC accuracy. |

FAQ
What is the maximum operating frequency of the TM4C1230H6PMI?
The TM4C1230H6PMI operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL driven by either the precision internal oscillator (PIOSC) or an external crystal (4–25 MHz). This frequency is fully supported across the entire industrial temperature range (-40°C to +85°C) and enables deterministic real-time execution for control loops and signal processing tasks within the TM4C1230H6PMI.
Does the TM4C1230H6PMI include an integrated USB physical layer (PHY)?
Yes, the TM4C1230H6PMI integrates a full-speed USB 2.0 physical layer (PHY) compliant with USB specification revision 2.0. This eliminates the need for an external transceiver chip. The USB0EPEN, USB0P, and USB0N pins connect directly to the USB connector, and the on-chip PHY supports suspend/resume, SOF generation, and endpoint buffer management - all managed by the TM4C1230H6PMI's USB controller.
How much on-chip flash and SRAM does the TM4C1230H6PMI provide?
The TM4C1230H6PMI includes 256 KB of on-chip flash memory with built-in error-correcting code (ECC) and 32 KB of general-purpose SRAM. Flash is organized for efficient code execution and data storage, while SRAM supports stack, heap, and peripheral buffers. An additional 8 KB ROM contains the TivaWare™ boot loader and peripheral driver library, reducing flash usage and improving firmware reliability for the TM4C1230H6PMI.
Is the TM4C1230H6PMI pin-compatible with other Tiva C Series microcontrollers?
The TM4C1230H6PMI uses a 100-pin LQFP package with a pinout aligned to the TM4C123x family baseline, enabling partial layout reuse with devices like TM4C123GH6PM. However, pin compatibility is not guaranteed across all variants due to differences in peripheral enablement, alternate function mapping, and power rail requirements. Always verify pin functions and electrical characteristics against the specific TM4C1230H6PMI datasheet before board reuse.
What debug interfaces does the TM4C1230H6PMI support?
The TM4C1230H6PMI supports both JTAG and Serial Wire Debug (SWD) interfaces via dedicated pins (TCK, TMS, TDI, TDO, nTRST, SWDIO, SWCLK). These interfaces enable full-featured debugging - including breakpoints, watchpoints, register inspection, and real-time trace - using TI's XDS110 debug probe or third-party CMSIS-DAP compliant tools. Debug access remains functional even when the TM4C1230H6PMI is running from internal flash or ROM.
