Product details
Overview
TM4C1236E6PMI7 from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, and integrated USB 2.0 OTG, PWM, ADC (12-bit, 1MSPS), and multiple serial interfaces (UART, I²C, SSI). It operates at up to 80 MHz and supports industrial temperature range (–40°C to +85°C) in a 64-pin LQFP package, used in motor control, industrial automation, and smart sensor nodes.
For engineers reviewing the TM4C1236E6PMI7 datasheet, TM4C1236E6PMI7 pinout, TM4C1236E6PMI7 application, or TM4C1236E6PMI7 equivalent, key selection criteria include its integrated USB PHY, deterministic floating-point performance, on-chip ROM bootloader, configurable GPIO slew rate, and support for TivaWare™ software stack in resource-constrained embedded designs.
Technical Context
The TM4C1236E6PMI7 implements a full-featured ARM Cortex-M4F core with hardware FPU, NVIC supporting 64 interrupt lines, and memory protection unit (MPU) for secure task isolation. Its system-level integration includes a programmable clock tree with PLL, power gating per peripheral, and deep-sleep modes with wake-on-event capability.
Peripherals are tightly coupled via the μDMA controller with 32-channel arbitration, enabling zero-CPU-overhead transfers between ADC, UART, and memory. Analog subsystem features four independent 12-bit ADC sample sequencers with hardware averaging and internal temperature sensor-critical for closed-loop thermal management in real-time control systems.

What debug interfaces are supported by the TM4C1236E6PMI7?
The TM4C1236E6PMI7 supports JTAG and ARM Serial Wire Debug (SWD) interfaces for programming and real-time debugging. Both interfaces use dedicated pins (TCK, TMS, TDI, TDO, nTRST for JTAG; SWDIO, SWCLK, nRESET for SWD) and are compatible with standard debug probes including TI's XDS110 and third-party tools like Segger J-Link. The TM4C1236E6PMI7 also includes SWO trace output for instruction and data trace streaming via Serial Wire Viewer.
How much on-chip memory does the TM4C1236E6PMI7 provide?
The TM4C1236E6PMI7 includes 256 KB of on-chip Flash memory for program storage and 32 KB of general-purpose SRAM for runtime data. Additionally, it contains 32 KB of ROM holding the TivaWare™ peripheral driver library and a factory-programmed bootloader supporting UART, USB, and CAN-based firmware updates. The Flash supports sector erase (128 bytes), page programming, and read-while-write capability for seamless firmware upgrades.
Is the TM4C1236E6PMI7 qualified for industrial temperature operation?
Yes, the TM4C1236E6PMI7 is rated for industrial temperature operation from –40°C to +85°C ambient. It is manufactured and tested to meet TI's industrial-grade qualification standards, including extended temperature cycling, high-temperature operating life (HTOL), and electrostatic discharge (ESD) robustness per ANSI/ESDA/JEDEC JS-001.
