TM4C1233H6PGE 概要
A microcontroller unit (MCU) is a single-chip computer that integrates a processor core, memory, and peripherals on one die. Within the semiconductor hierarchy, the TM4C1233H6PGE belongs to the 32-bit embedded microcontroller class, part of the Tiva C Series TM4C123x family built on the Arm Cortex-M4F architecture, which adds a hardware single-precision FPU, DSP instructions, and a Memory Protection Unit (MPU) on top of the standard Cortex-M core.
Key features include the 80 MHz core with integrated FPU and MPU, 256 KB of on-chip flash with in-system programming support, 32 KB of SRAM, and a rich peripheral set: up to two CAN 2.0 controllers, USB 2.0 device, multiple UART, SSI, and I2C modules, 12-bit ADCs, PWM generators, and a battery-backed hibernate module with real-time clock. This combination makes the device well suited to mixed-signal industrial control where deterministic real-time response and robust fieldbus connectivity are required.
Technically, the device uses the Tiva C Series 123x platform with a nested vectored interrupt controller (NVIC), SysTick timer, and both a precision internal oscillator and main oscillator inputs. Flash-based memory supports firmware updates via CAN or UART bootloaders, easing field maintenance in deployed equipment.
Typical applications cited by TI include remote monitoring, electronic point-of-sale machines, test and measurement equipment, network appliances and switches, factory automation, HVAC and building control, and fire and security systems.
A key design consideration is SRAM budgeting: enabling USB stacks and RTOS middleware can consume several kilobytes of the 32 KB SRAM, so applications needing more headroom should evaluate the TM4C123GH6PGE variant or the TM4C129x class.

主な用途
TM4C1233H6PGE の用途: 6 件s: Factory Automation and PLC Nodes, Remote Monitoring and Telemetry, Test and Measurement Equipment, Electronic Point-of-Sale Machines, HVAC and Building Control, Fire and Security Systems.
Factory Automation and PLC Nodes
The TM4C1233H6PGE fits factory automation nodes because its dual CAN 2.0 controllers provide native fieldbus connectivity, while the 80 MHz Cortex-M4F with hardware FPU executes deterministic control loops for actuators and I/O scanning. In a typical deployment the MCU runs an RTOS, services CAN frames with hardware message objects to minimize CPU load, and uses its 12-bit ADCs and PWM generators for analog I/O and actuator drive. The 256 KB flash accommodates protocol stacks and OTA-updatable firmware via a CAN bootloader, reducing maintenance visits. Its industrial peripheral mix and real-time NVIC interrupt latency make it a dependable mid-range automation controller where higher-end Sitara devices would be over-budget.
おすすめ
Remote Monitoring and Telemetry
For remote monitoring equipment, the TM4C1233H6PGE offers a low-power hibernate module with battery-backed RTC for time-stamped logging and wake-on-event operation, extending battery life in unattended sites. The 80 MHz Cortex-M4F processes sensor samples - including FFT-based vibration analytics using DSP instructions and the FPU - while 256 KB flash stores data logging firmware and 32 KB SRAM buffers telemetry frames. Dual CAN and multiple UARTs connect to modems and local fieldbus simultaneously. Firmware can be updated in the field through a UART or CAN bootloader, which is critical for geographically dispersed installations where physical access is costly and downtime directly impacts monitoring continuity.
おすすめ
Test and Measurement Equipment
The TM4C1233H6PGE serves benchtop and portable test instruments where its 12-bit ADCs, timers, and PWM/DAC-companion peripherals implement stimulus and capture channels, while the 80 MHz Cortex-M4F with FPU performs calibration math, averaging, and DSP filtering on the fly. USB 2.0 device connectivity provides a plug-and-play interface to host PC software without external bridge chips, and the hibernate RTC timestamps logged measurements. The 256 KB flash holds multiple instrument profiles and a USB bootloader for firmware updates shipped as field upgrades. Deterministic NVIC interrupt response keeps time-critical measurement loops stable, making the MCU a cost-effective control core for handheld meters and industrial calibrators.
おすすめ
Electronic Point-of-Sale Machines
Electronic point-of-sale hardware benefits from the TM4C1233H6PGE's USB 2.0 device interface for PC and payment-terminal connectivity, plus multiple UARTs and SSI for receipt printers, card readers, and keypads. The 80 MHz Cortex-M4F handles transaction state machines and display refresh with headroom, and the battery-backed RTC in the hibernate module maintains correct transaction timestamps through power interruptions - essential for receipt integrity. The 256 KB flash supports secure bootloader architectures and in-field firmware updates, while CAN provides an option for networked POS clusters in retail back-office topologies. Its industrial temperature robustness also suits kiosk and vending machine deployments with wide environmental ranges.
おすすめ
HVAC and Building Control
In HVAC and building automation controllers, the TM4C1233H6PGE combines dual CAN 2.0 for BACnet-oriented fieldbus segments, 12-bit ADCs for temperature and pressure sensing, and PWM outputs for damper and valve actuation. The 80 MHz Cortex-M4F executes PID control loops - accelerated by the hardware FPU - for precise temperature and airflow regulation, while the hibernate module's RTC maintains schedules through brownouts. With 256 KB flash there is room for protocol stacks, trending logs, and a CAN/UART field-update bootloader that lets facility teams patch firmware without dismantling control panels. Its peripheral breadth consolidates sensing, actuation, and communication on one 144-pin LQFP device, cutting BOM cost.
おすすめ
Fire and Security Systems
Fire alarm and security panels leverage the TM4C1233H6PGE's battery-backed hibernate RTC for event time-stamping, dual CAN for networked panel-to-panel communication, and multiple UART/GPIO resources for zone monitoring and siren drive. The 80 MHz Cortex-M4F runs supervisory state machines and sensor-line algorithms with deterministic interrupt latency, while the 256 KB flash holds certification-critical firmware that can be updated via a locked-down bootloader. The 32 KB SRAM comfortably hosts event queues for alarm history. Robust peripherals, real-time response, and fieldbus options let one MCU consolidate detection processing, annunciation, and network reporting - an economical architecture for distributed life-safety and access-control installations.

設計ノート
Budget the 32 KB SRAM before committing to middleware: a full USB device stack plus an RTOS with TCP or CANopen layers can consume 10-15 KB, leaving limited headroom for buffers. Estimate worst-case heap and stack use with the linker map and runtime watermarking. If your application requires more RAM, evaluate the TM4C123GH6PGE or step up to the TM4C129x class, which shares TivaWare tooling for easier migration.
The 144-LQFP (20x20 mm) exposes a 0.5 mm pin pitch - use 4-mil trace/space design rules and place a solid ground plane on layer 2. Decouple every VDD pin pair with 0.1 uF ceramics placed within 2 mm of the pins, plus one bulk 10 uF capacitor per supply domain. Keep the CAN transceiver close to the CAN pins with a series common-mode choke toward the connector to improve EMC performance in industrial cabinets.
For firmware updates in deployed units, implement the TI ROM/flash bootloader over CAN or UART from the start of the project rather than retrofitting it. Reserve the designated bootloader pins and verify that your RS-485 or CAN physical layer is active during reset. This avoids costly service visits and enables field patching of security and automation firmware - a pattern used throughout TI's Tiva C reference designs.
