Product details
Overview
TM4C1236E6PMI7R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, integrated USB 2.0 OTG, dual CAN 2.0A/B controllers, and 12-bit ADC with 12 channels - deployed in industrial motor control and smart sensor edge nodes.
For engineers reviewing the TM4C1236E6PMI7R datasheet, TM4C1236E6PMI7R pinout, TM4C1236E6PMI7R application, or TM4C1236E6PMI7R equivalent, key selection criteria include its 80 MHz CPU clock, USB+CAN+SSI+I²C peripheral integration, -40°C to +85°C industrial temperature grade, and QFP-128 package compatibility with Tiva C Series development workflows.
Technical Context
The TM4C1236E6PMI7R implements a full-featured ARM Cortex-M4F core with hardware floating-point unit (FPU), memory protection unit (MPU), and nested vectored interrupt controller (NVIC) supporting up to 80 interrupts. It integrates μDMA with 32-channel capability for offloading peripheral-to-memory transfers.
System-level features include programmable clock gating per peripheral, multiple low-power sleep modes (Sleep, Deep Sleep, Hibernate), and on-chip ROM with TivaWare™ driver library. Analog subsystem includes two independent 12-bit ADCs (12-channel total, 1 MSPS aggregate), internal temperature sensor, and analog comparators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TM4C123GH6PM | Same core, 256 KB Flash, but adds 1 MB EEPROM and enhanced USB host stack; no CAN2 controller. | Better suited for USB-host-centric designs (e.g., printer controllers); lacks second CAN bus required for dual-network automotive use. | Select TM4C123GH6PM only if EEPROM persistence and USB host priority outweigh dual-CAN requirement. |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB Flash, 192 KB SRAM, single CAN, no integrated USB PHY (requires external transceiver). | Higher performance and memory for advanced graphics or audio processing; USB implementation increases BOM cost and layout complexity. | Choose STM32F407VGT6 when raw compute throughput or large code footprint dominates over integrated USB/CAN coexistence. |
Compared with TM4C123GH6PM and STM32F407VGT6, the TM4C1236E6PMI7R uniquely balances dual-CAN, integrated USB PHY, and industrial temperature rating in a single 128-pin LQFP - making it optimal for space-constrained, fieldbus-rich edge nodes where mixed-protocol connectivity is non-negotiable.

FAQ
What is the maximum operating frequency of the TM4C1236E6PMI7R?
The TM4C1236E6PMI7R operates at a maximum CPU clock frequency of 80 MHz, derived from an internal PLL locked to the precision 16 MHz main oscillator. This frequency is fully supported across the full industrial temperature range (-40°C to +85°C) and enables deterministic real-time execution of control loops and communication stacks within the TM4C1236E6PMI7R's architecture.
Does the TM4C1236E6PMI7R include an integrated USB physical layer?
Yes, the TM4C1236E6PMI7R integrates a full-speed USB 2.0 OTG physical layer (PHY) directly on-die, eliminating the need for an external transceiver. This allows direct connection to USB cables and supports device, host, and OTG roles - a key differentiator confirmed in the TI SPMS354E datasheet Section 13 and validated in TM4C1236E6PMI7R reference designs.
How many CAN controllers does the TM4C1236E6PMI7R support?
The TM4C1236E6PMI7R supports two independent CAN 2.0A/B controllers (CAN0 and CAN1), each with dedicated message RAM, filter banks, and transmit/receive FIFOs. This dual-CAN capability is explicitly documented in the "Peripheral Summary" table (Section 1.2) and functional descriptions (Section 13.1) of the TM4C1236E6PMI7R datasheet.
What is the ADC resolution and sampling rate of the TM4C1236E6PMI7R?
The TM4C1236E6PMI7R features two 12-bit successive-approximation ADCs with a combined 12-channel input multiplexer and aggregate sampling rate up to 1 MSPS. Each ADC supports hardware averaging, differential input mode, and programmable sample-and-hold timing - specifications verified in Section 12.3 of the official TM4C1236E6PMI7R production datasheet.
Is the TM4C1236E6PMI7R pin-compatible with other Tiva C Series MCUs?
The TM4C1236E6PMI7R uses a 128-pin LQFP package with a pinout aligned to the TM4C123x family baseline, enabling mechanical compatibility with boards designed for TM4C123GH6PM and TM4C123BE6PM. However, peripheral pin mappings differ across variants - for example, CAN1 signals appear on different GPIO ports than CAN0 - so full pin-for-pin software compatibility requires validation against the specific variant's datasheet.
