TM4C123AE6PMIR ARM Cortex-M4 Microcontroller, 64-LQFP Package

TM4C123AE6PMIR Overview

The TM4C123AE6PMIR is a high-performance, industrial-grade 32?bit microcontroller built around an ARM Cortex?M4F core with a hardware floating?point unit. It targets embedded control designs that need more compute and more peripheral integration than typical 8? or 16?bit MCUs. With a top clock of 80 MHz, non?volatile program storage, on?chip SRAM, integrated analog and digital peripherals, and standard 3.3 V I/O, this device simplifies system design and shortens time to market.

TM4C123AE6PMIR Key Features

• 32?bit Cortex?M4F core with floating?point unit ?? enables faster math and DSP operations compared with 8?bit MCUs, improving throughput for control and signal processing.
• 80 MHz maximum clock ?? delivers higher single?thread performance and lower interrupt latency versus lower?clocked alternatives.
• 256 KB Flash and 32 KB SRAM ?? provides more on?chip code and data storage to reduce external memory needs and simplify BOM compared with smaller parts.
• 12?bit ADC ?? integrated high?resolution analog inputs support more accurate sensor measurements than typical 10?bit converters.
• USB 2.0 OTG support ?? enables direct host/device connections for firmware updates, data logging, or USB peripherals without extra controllers.
• Rich peripheral set (UART, I2C, SPI, PWM, timers) ?? allows greater system integration and reduces external components in multi?interface applications.
• Industrial temperature range ?? suitable for harsher environments and longer field life compared with commercial?grade devices.
• 64?pin LQFP package ?? balances pin count and PCB area for medium?pin systems that need many I/O lines and peripherals.

Typical Applications

• Industrial motor control and servo systems that require deterministic interrupt handling, higher math throughput, and integrated PWM with precise ADC sampling for closed?loop control.
• Building automation and HVAC controllers that benefit from multiple comms interfaces, USB connectivity, and the memory capacity to host complex control firmware and logging.
• Data acquisition and portable instrumentation where 12?bit ADC accuracy, on?chip memory, and USB connectivity enable compact, self?contained measurement systems.
• Human?machine interfaces and embedded gateways that need multiple UART/I2C/SPI buses, display control, and enough Flash to store UI assets and communication stacks.

TM4C123AE6PMIR Advantages vs Typical Alternatives

This device offers a stronger combination of compute and integration than many 8? or 16?bit controllers: a 32?bit Cortex?M4F core at 80 MHz plus an FPU yields faster numeric code and DSP routines. With 256 KB Flash and 32 KB SRAM, it often eliminates external memory used with lower?density parts. The integrated 12?bit ADC, USB 2.0 OTG, and multiple serial interfaces reduce BOM and board complexity when compared to solutions that require separate analog, comms, or USB controllers.
