Product details
Overview
TM4C1230D5PMIR from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 80 MHz operation, 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 serves as a main system controller in industrial motor control, smart sensor nodes, and USB-connected embedded devices.
For engineers reviewing the TM4C1230D5PMIR datasheet, TM4C1230D5PMIR pinout, TM4C1230D5PMIR application, or TM4C1230D5PMIR equivalent, key selection factors include its 80 MHz FPU-enabled core, 12-bit 1MSPS ADC with hardware averaging, USB OTG support, 100-pin LQFP package with configurable GPIOs, and industrial temperature range (–40°C to +105°C).
Technical Context
The TM4C1230D5PMIR integrates a single-core ARM Cortex-M4F processor with floating-point unit and memory protection unit (MPU), supporting Thumb-2 instruction set and deterministic real-time execution. It features a multi-layer AHB bus matrix enabling concurrent access to flash, SRAM, peripherals, and DMA.
System-level integration includes a programmable clock tree with PLL, multiple low-power sleep modes (Sleep, Deep Sleep, Hibernate), and on-chip voltage regulation. Peripheral interconnect supports hardware synchronization between timers, ADC triggers, and μDMA channels for deterministic sensor-to-USB data pipelines.
