It targets industrial control, remote monitoring, test and measurement, POS, HVAC/building automation, and fire/security applications per the TI datasheet SPMS350E.

What Are the Quick Answers Every TM4C1233H6PGE Buyer Needs?

Engineers shortlisting this MCU consistently ask the same core questions. Here are the direct, data-verified answers.

What is it? A Texas Instruments Tiva C Series TM4C123x 32-bit Arm Cortex-M4F microcontroller with a hardware single-precision FPU, DSP instructions, and a Memory Protection Unit (MPU), clocked at up to 80 MHz from either a main oscillator or an internal precision oscillator.

How much memory? 256 KB of on-chip flash with in-system programming support, plus 32 KB of SRAM. Flash firmware can be updated in the field through CAN or UART bootloaders.

Which connectivity is on-chip? Up to two CAN 2.0 controllers, USB 2.0 device, and multiple UART, SSI, and I2C modules. An external CAN transceiver (for example a TI SN65HVD230-class part) is required on the physical layer.

What about timing and analog? A battery-backed hibernate module with real-time clock, a nested vectored interrupt controller (NVIC), SysTick timer, 12-bit ADCs, and PWM generators.

Package and supply? 144-pin LQFP measuring 20x20 mm, surface mount. Supply voltage range is [DATA_NEEDED: Supply Voltage] and operating temperature range is [DATA_NEEDED: Operating Temperature]; note that the I-suffix TM4C1233H6PGEI variant designates the extended industrial temperature grade of identical silicon.

Availability and price? XAIPART lists 99,999 units in stock, MOQ 1, tiered pricing $10.95 (qty 1), $9.86 (qty 10), $8.80 (qty 100), $7.92 (qty 500), and $7.15 (qty 1,000) as of 2026-09-02. The lifecycle status is active.

How Do You Select and Design In the TM4C1233H6PGE?

Design-in success with this MCU depends on matching its verified capabilities to your system requirements and budgeting its resources carefully. Follow this process.

Step 1 — Confirm the real-time and fieldbus requirements. If your node must talk CAN 2.0 (CANopen, J1939 gateways, panel-to-panel networking), the TM4C1233H6PGE's dual CAN controllers are a distinguishing feature versus many mainstream Cortex-M parts that omit CAN. Each controller handles standard and extended frames and is clocked from the system clock with programmable bit timing per the TI datasheet.

Step 2 — Budget the 32 KB SRAM. This is the single most important constraint. Enabling USB stacks and RTOS middleware can consume several kilobytes of the 32 KB SRAM. Applications needing more headroom should evaluate the TM4C123GH6PGE variant or the TM4C129x class. Plan your RAM map before committing to middleware.

Step 3 — Use the FPU and DSP instructions for math-heavy loops. The hardware single-precision FPU executes PI and field-oriented control algorithms without software float overhead, and DSP instructions support FFT-based condition monitoring at the 80 MHz core rate.

Step 4 — Exploit the hibernate RTC. The battery-backed hibernate module with real-time clock enables wake-on-event operation and time-stamped logging — essential for remote telemetry, POS transaction integrity, and building-control schedules surviving brownouts.

Step 5 — Plan field updates. The flash supports in-system programming and CAN/UART bootloader updates, easing maintenance in deployed equipment. For safety-critical firmware (fire/security), use a locked-down bootloader architecture.

Step 6 — Choose the toolchain. Supported environments include TI Code Composer Studio (CCS) with TivaWare for C Series libraries, ARM Keil MDK, IAR Embedded Workbench, and GCC-based toolchains. Debugging uses JTAG or SWD via the TI XDS100/XDS110 or the ICDI interface on TI LaunchPad-style boards. TivaWare provides peripheral driver libraries, a USB stack, and bootloader source code, significantly reducing firmware effort.

Step 7 — Verify clocking strategy. Per the TI datasheet (SPMS350E), the core clock derives from the main oscillator or the internal precision oscillator through the system clock configuration; select crystal precision for CAN bit-timing accuracy.

Step 8 — Confirm the temperature grade before ordering. The commercial-grade TM4C1233H6PGE and industrial-grade TM4C1233H6PGEI are the same silicon; the I suffix designates the extended industrial operating temperature range appropriate for factory-floor, outdoor, and automotive-adjacent environments.

What Are the Best Drop-In Alternatives and How Does the TM4C1233H6PGE Compare?

All verified alternatives come from the same TM4C123x LQFP-144 family, which is pin-to-pin compatible per TI's family pinout documentation. No true pin-to-pin cross-brand equivalent exists — the 144-pin LQFP pinout is TI-proprietary; functionally comparable STM32F446VCT6 or STM32F407 class parts require PCB redesign because pin mapping differs.

TM4C1233H6PGE vs TM4C123GH6PGE: choose the G-series for new designs needing the fullest TM4C123x peripheral set, and the TM4C1233H6PGE when dual CAN 2.0 and existing design baselines match your requirements. Both are 80 MHz, 256 KB flash, 32 KB SRAM, 144-pin LQFP parts, so switching requires only firmware-level verification.

TM4C1233H6PGE vs TM4C1294NCPDT: choose the TM4C1233H6PGE for a cost-effective 80 MHz Cortex-M4F with dual CAN and 32 KB SRAM in compact industrial nodes; choose the TM4C1294NCPDT when you need Ethernet MAC/PHY, 120 MHz clock, 1 MB flash, and 256 KB SRAM for networked gateways and data-heavy applications.

What Is the Market Position, Lifecycle Status, and Supply Situation?

The TM4C1233H6PGE is an active part in Texas Instruments' portfolio — the TI product page lists it with current ordering and quality information, not as discontinued. TI continues to support the Tiva C Series with TivaWare libraries in Code Composer Studio and Keil MDK.

However, the Tiva C line is mature; for brand-new designs, TI often points engineers toward newer MSPM0 or Sitara class devices, so plan long-term sourcing accordingly. On the supply side, XAIPART holds 99,999 units in stock with MOQ 1 as of 2026-09-02, and DigiKey lists the industrial-temperature TM4C1233H6PGEI variant with same-day shipping as of 2026-08-30. MCU pricing fluctuates with allocation cycles — the current XAIPART tier structure runs from $10.95 at qty 1 to $7.15 at qty 1,000 as of 2026-09-02, so always verify current stock and pricing on the distributor page before ordering.

What Trends and Buying Signals Should Engineers Watch?

Three trends anchored to verified specs should shape your purchasing and design decisions.

1. SRAM-driven platform migration. As edge analytics push more middleware into embedded nodes, 32 KB SRAM becomes the binding constraint. FFT-based vibration analytics and USB stacks fit today, but teams scaling up should pre-validate the TM4C123GH6PGE or TM4C129x class — the TM4C1294NCPDT offers 120 MHz, 1 MB flash, and 256 KB SRAM with Ethernet MAC/PHY. Designing your memory map now keeps the upgrade path open within the pin-compatible LQFP-144 family.

2. Fieldbus relevance of dual CAN. The dual CAN 2.0 controllers remain a differentiator as CANopen and J1939 gateways persist in factory automation and building control. When qualifying the TM4C123BH6PGE or TM4C1231H6PGE as alternates, verify CAN instance count — reduced-config variants may not preserve both controllers.

3. Temperature-grade and lifecycle risk management. With the Tiva C line mature and TI steering new designs toward MSPM0 and Sitara, buyers should lock in volume pricing while stock is deep — the $7.15/k-unit tier as of 2026-09-02 reflects a favorable window — and specify the TM4C1233H6PGEI industrial grade for harsh environments to avoid last-minute qualification churn. Confirm the temperature-grade suffix (I vs commercial) on every purchase order.
