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, integrated Ethernet MAC, no USB OTG PHY | Requires external Ethernet PHY; lacks integrated USB PHY but adds 10/100 Ethernet interface | Select when Ethernet connectivity is primary and USB is secondary or handled externally |
| STM32F407VGT6 | ARM Cortex-M4F @ 168 MHz, 1 MB flash, 192 KB SRAM, USB OTG HS/FS, no native CAN FD support | Single CAN 2.0B controller; USB HS requires external ULPI PHY; different peripheral mapping and register layout | Select when higher CPU throughput and larger memory are needed, and dual CAN is not required |
Compared with TM4C1232H6PMI7, TM4C1294NCPDT trades USB OTG PHY for Ethernet MAC and larger memory, while STM32F407VGT6 offers higher clock speed and memory but only one CAN interface and no integrated USB PHY - making TM4C1232H6PMI7 optimal for USB + dual-CAN edge nodes with strict BOM cost targets.

FAQ
What is the maximum operating frequency of the TM4C1232H6PMI7?
The TM4C1232H6PMI7 operates at a maximum system clock frequency of 80 MHz, achieved using its internal PLL with either the internal precision oscillator (±1% accuracy) or an external crystal. This frequency applies to the Cortex-M4F core, bus matrix, and all on-chip peripherals - verified across the full -40°C to +85°C temperature range and 3.0–3.6 V supply.
Does the TM4C1232H6PMI7 include an integrated USB PHY?
Yes, the TM4C1232H6PMI7 includes a fully integrated USB 2.0 OTG PHY compliant with USB specification revision 2.0. It supports full-speed (12 Mbps) host, device, and OTG modes without requiring external PHY components - only standard USB-series resistors and ESD protection diodes are needed on the D+ and D− lines.
How many CAN interfaces does the TM4C1232H6PMI7 support?
The TM4C1232H6PMI7 supports two independent CAN 2.0A/B controllers (CAN0 and CAN1), each with dedicated message RAM (64 message objects), acceptance filtering, and transmit/receive FIFOs. Both controllers operate concurrently and can be configured for different bit rates and protocols - enabling dual-network applications like powertrain + body CAN domains.
What is the ADC resolution and sampling rate of the TM4C1232H6PMI7?
The TM4C1232H6PMI7 features a 12-bit successive-approximation ADC with up to 1 million samples per second (1 MSPS) aggregate throughput. It includes 12 analog input channels, four independent sample sequencers, hardware oversampling (up to 16×), and digital comparators - all accessible without CPU intervention via μDMA triggers.
Is the TM4C1232H6PMI7 pin-compatible with other Tiva C Series MCUs?
No, the TM4C1232H6PMI7 is not pin-compatible with other Tiva C Series MCUs such as TM4C1294 or TM4C123GH6PM. Its 64-pin LQFP package has unique signal assignments - particularly for USB, CAN, and clock inputs - and differs in GPIO count, peripheral mapping, and power pin distribution. Migration requires PCB redesign and firmware adaptation.
