Product details
Overview
TM4C1233E6PZI7 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, SPI, I²C). It serves as a main system controller in industrial motor control, sensor hubs, and USB-connected embedded devices.
For engineers reviewing the TM4C1233E6PZI7 datasheet, TM4C1233E6PZI7 pinout, TM4C1233E6PZI7 application, or TM4C1233E6PZI7 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +105°C industrial temperature grade, USB device/host/OTG capability, hibernation module with RTC and battery-backed memory, and support for TivaWare™ software stack.
Technical Context
The TM4C1233E6PZI7 integrates a single-core ARM Cortex-M4F processor with hardware floating-point unit (FPU), memory protection unit (MPU), and nested vectored interrupt controller (NVIC). It supports Thumb-2 instruction set, 32-bit data path, and deterministic real-time execution with sub-100 ns interrupt latency.
System-level integration includes a hibernation module with dedicated 32.768 kHz RTC oscillator, battery-backed SRAM (2 KB), and VBAT power domain; plus μDMA controller supporting 32 channels with scatter-gather capability across peripherals including ADC, UART, and timers.
Key Specifications

Pinout & Package
TM4C1233E6PZI7 is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments are defined per TI SPMS349E datasheet Rev E (June 2014), with dedicated JTAG/SWD debug pins, USB D+/D−, VDDA/VSSA analog supply, and GPIOs multiplexed across 10 peripheral blocks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power and ground | 3.3 V nominal supply; requires local 100 nF + 4.7 µF decoupling per power domain. |
| VDDA, VSSA | Analog power and ground | Isolated analog supply domain for ADC and internal reference - must be filtered separately from digital rails. |
| USB0DP, USB0DM | USB 2.0 differential pair | Integrated PHY supports full-speed (12 Mbps) device/host/OTG; requires 27 Ω series resistors and 15 kΩ pull-up on DP for device mode. |
| PD0, PD1 | UART0 TX/RX | Default UART0 interface; also supports I²C0 SCL/SDA and timer functions - enables bootloader communication over USB-to-UART bridge. |
| PH0, PH1 | JTAG TCK/TMS | Standard ARM SWD/JTAG debug interface; TDO/TDI shared with GPIOs - supports in-circuit debugging and programming via TI XDS100v3 or CMSIS-DAP. |
| HIBERNATE_RTCCLK | Hibernate module clock input | Accepts external 32.768 kHz crystal or clock source - required for RTC operation during hibernation. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-Point Unit (FPU) | Hardware IEEE 754 single-precision FPU accelerates motor control algorithms and sensor fusion without software emulation overhead. |
| Hibernate Module | Independent power domain with RTC, battery-backed SRAM, and wake-on-RTC-match or external pin - reduces system standby power to < 2 µA. |
| μDMA Controller | 32-channel memory-mapped DMA with scatter-gather support - offloads ADC sampling, UART transfers, and PWM updates from CPU. |
| Peripheral Integration | On-chip USB PHY, 12-bit ADC, 8 × PWM outputs, 2 × I²C, 4 × UART, 2 × SPI, and analog comparators - eliminates need for external interface ICs. |
| TivaWare™ Support | TI-provided driver library, USB stack, and RTOS abstraction layer - accelerates development of USB HID, CDC, and mass storage applications. |
