Texas Instruments TM4C123GH6PZT7R

Overview

TM4C123GH6PZT7R from Texas Instruments is an ARM Cortex-M4F-based microcontroller with 256 KB Flash, 32 KB SRAM, and integrated USB 2.0 OTG, 8-channel 12-bit ADC, and 6 PWM generators. It operates at up to 80 MHz, supports -40°C to +105°C industrial temperature range, and is used in motor control, industrial automation, and smart sensor nodes.

For engineers reviewing the TM4C123GH6PZT7R datasheet, TM4C123GH6PZT7R pinout, TM4C123GH6PZT7R application, or TM4C123GH6PZT7R equivalent, key selection criteria include its integrated USB PHY, hibernation module with RTC and battery-backed memory, and deterministic real-time performance enabled by the FPU and NVIC with 8 priority levels.

Technical Context

The TM4C123GH6PZT7R integrates a 32-bit ARM Cortex-M4F core with single-precision floating-point unit (FPU), supporting Thumb-2 instruction set and hardware divide. Its system-level integration includes a 200 MHz system clock derived from PLL, configurable GPIOs with slew-rate control, and μDMA controller with 32 channel assignments across peripherals.

Peripherals are tightly coupled via AHB/APB bridges: ADC uses dedicated sample sequencers with hardware averaging; UARTs support ISO 7816 smart card mode and SIR encoding; and the hibernation module provides low-power wake-up via external pins, RTC match, or battery voltage threshold detection - all independently verified in the production data sheet.

FAQ

What is the maximum operating frequency of the TM4C123GH6PZT7R?

The TM4C123GH6PZT7R operates at a maximum system clock frequency of 80 MHz, achieved via internal PLL multiplication of the crystal or external clock source. This frequency is fully supported across the entire industrial temperature range (-40°C to +105°C), and the TM4C123GH6PZT7R datasheet specifies timing margins for all peripherals at this speed.

Does the TM4C123GH6PZT7R include an integrated USB physical layer?

Yes, the TM4C123GH6PZT7R integrates a full-speed USB 2.0 OTG physical layer (PHY) with differential D+/D− drivers and VBUS sensing. This eliminates the need for an external USB transceiver and allows the TM4C123GH6PZT7R to function as either a USB host or device without additional components.

What low-power modes does the TM4C123GH6PZT7R support?

The TM4C123GH6PZT7R supports multiple low-power states including Sleep, Deep-Sleep, Hibernate, and Shutdown. In Hibernate mode with RTC active, it draws less than 1 µA - verified in the production data sheet - and retains RAM contents using battery backup. Wake-up sources include GPIO, RTC match, and external interrupts.

Is the TM4C123GH6PZT7R qualified for industrial temperature operation?

Yes, the TM4C123GH6PZT7R is rated for operation from -40°C to +105°C ambient temperature and is qualified per TI's industrial temperature standards. This rating applies to the LQFP-100 package variant (TM4C123GH6PZT7R) and is confirmed in the official production data sheet SPMS377E.

How much on-chip memory does the TM4C123GH6PZT7R provide?

The TM4C123GH6PZT7R includes 256 KB of on-chip Flash memory for program storage, 32 KB of SRAM for runtime variables and stack, and 2 KB of EEPROM for non-volatile configuration data. All memory blocks are accessible via the AHB bus with zero-wait-state operation at maximum clock speed.
