LM3S600-IGZ50-C2T from Texas Instruments is a 32-bit ARM Cortex-M3 microcontroller with 256 KB flash, 64 KB SRAM, integrated analog comparators, UART/SSI/I²C interfaces, and motor control peripherals. It operates at up to 50 MHz, supports 3.3 V operation, and targets real-time embedded control in industrial automation and motor drives.
For engineers reviewing the LM3S600-IGZ50-C2T datasheet, LM3S600-IGZ50-C2T pinout, LM3S600-IGZ50-C2T application, or LM3S600-IGZ50-C2T equivalent, key selection criteria include its 50 MHz CPU clock, 256 KB on-chip flash with write protection, dual analog comparators with internal reference, NVIC-based interrupt handling, and QFP-100 package compatibility for space-constrained control modules.
Technical Context
The LM3S600-IGZ50-C2T implements the ARMv7-M architecture with Thumb-2 instruction set, nested vectored interrupt controller (NVIC), and memory protection unit (MPU). It integrates a system timer (SysTick), watchdog timer, and configurable GPIO with alternate functions including UART, SSI, and I²C.
Its analog subsystem includes two independent comparators with programmable internal voltage reference (1.65 V or 2.5 V), while the clock system supports multiple sources (PIOSC, MOSC, PLL) and dynamic power management with sleep modes controlled via the SCB.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3S610-IQR50-C2T | Same core and memory, but QFN-100 package (no thermal pad), different pinout for USB signals (NC vs routed) | Preferred where board area is constrained and USB functionality is unused | Select when thermal pad is unnecessary and footprint density outweighs mechanical robustness |
| TM4C123GH6PM | Successor family with 80 MHz Cortex-M4F, FPU, enhanced peripherals, and larger memory (256 KB flash/32 KB SRAM) | Required for floating-point math, Ethernet, or CAN FD in next-gen designs | Choose for new designs needing higher performance or extended lifecycle; not drop-in compatible due to pinout and register map changes |
Compared with LM3S600-IGZ50-C2T, LM3S610-IQR50-C2T offers identical functionality in a smaller QFN package but lacks thermal pad support, while TM4C123GH6PM provides architectural upgrades (FPU, higher clock) at the cost of full hardware/software requalification.

FAQ
What is the maximum operating frequency of the LM3S600-IGZ50-C2T?
The LM3S600-IGZ50-C2T operates at a maximum CPU clock frequency of 50 MHz. This speed is achieved using the internal PLL with an external crystal or oscillator input. The device maintains full specification compliance-including flash access timing and peripheral operation-at this frequency under rated voltage (3.3 V) and temperature (–40°C to +85°C) conditions. All timing-critical features such as PWM generation and UART baud rate accuracy are validated at 50 MHz in the official Texas Instruments production datasheet.
Does the LM3S600-IGZ50-C2T include an integrated ADC?
No, the LM3S600-IGZ50-C2T does not include an analog-to-digital converter (ADC). Instead, it integrates two analog comparators (COMP0 and COMP1) with programmable internal voltage references (1.65 V or 2.5 V) and hysteresis control. These comparators support overvoltage/undervoltage detection and zero-crossing sensing but do not provide digitized analog measurements. For ADC functionality, external converters or migration to the TM4C123 family-which includes 12-bit ADCs-is required.
What package type is used for the LM3S600-IGZ50-C2T?
The LM3S600-IGZ50-C2T uses a 100-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm lead pitch and an exposed thermal pad on the underside. This package is specified in the Texas Instruments datasheet as "IGZ" suffix and supports standard surface-mount assembly processes. The thermal pad improves heat dissipation during sustained 50 MHz operation and is recommended to be soldered to a dedicated PCB copper pour for optimal thermal performance in motor control applications.
Can the LM3S600-IGZ50-C2T support USB communication?
No, the LM3S600-IGZ50-C2T does not support USB communication. Although some pins (e.g., USB0VBUS, USB0ID) appear in the full pinout table, they are designated as no-connect (NC) for this specific variant per the LM3S600 datasheet Section 15.1. USB capability was introduced in later Stellaris families (e.g., LM3S8xx) and the TM4C series. For USB-enabled designs, engineers should consider the TM4C123GH6PM or evaluate external USB-to-UART bridge ICs interfaced via the LM3S600-IGZ50-C2T's UART peripherals.
What debug interface does the LM3S600-IGZ50-C2T support?
The LM3S600-IGZ50-C2T supports JTAG debugging via a 5-pin interface (TCK, TMS, TDI, TDO, nTRST) compliant with IEEE 1149.1. It includes full SWD (Serial Wire Debug) compatibility through the same physical pins, enabling use with TI's ICDI-based debuggers (e.g., Tiva C Series LaunchPad) and third-party tools like Segger J-Link. The Cortex-M3 core implements hardware breakpoints, watchpoints, and real-time memory access during halt mode-features confirmed in the "JTAG Interface" chapter of the official LM3S600 datasheet.
