Product details
Overview
LM3S600-EQN50-C2 from Texas Instruments is a 32-bit ARM Cortex-M3 microcontroller with 64 KB flash, 24 KB SRAM, and integrated peripherals including UART, I²C, SSI, GPIO, timers, and analog comparators. It operates at up to 50 MHz and supports industrial temperature range (–40°C to +85°C) in a 50-pin QFP package. It serves as a system controller in motor control, sensor interface, and embedded automation applications.
For engineers reviewing the LM3S600-EQN50-C2 datasheet, LM3S600-EQN50-C2 pinout, LM3S600-EQN50-C2 application, or LM3S600-EQN50-C2 equivalent, key selection criteria include its 50 MHz Cortex-M3 core, on-chip memory configuration, peripheral set (dual UART, I²C master/slave, SSI), operating temperature grade, and QFP-50 package compatibility with legacy Stellaris-based designs.
Technical Context
The LM3S600-EQN50-C2 implements the ARMv7-M architecture with NVIC, SysTick, MPU, and debug support via JTAG. It integrates a programmable 8-channel PWM module, two 16-bit general-purpose timers (expandable to 32-bit), and a watchdog timer with windowed mode capability.
Its analog subsystem includes two independent analog comparators with internal voltage reference and interrupt capability. Clock management supports multiple sources (PIOSC, MOSC, PLL) with configurable dividers and power-saving sleep modes (Sleep, Deep-Sleep, Hibernate).

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDC | Power supply inputs | Digital core (VDDC), analog (VDDA), and I/O (VDD) rails - require separate decoupling per datasheet layout guidelines. |
| GND, GNDA, GNDC | Ground returns | Analog (GNDA), digital core (GNDC), and I/O (GND) grounds - must be connected to common ground plane with low-inductance paths. |
| PF0–PF3, PE0–PE5, PD0–PD7, PC0–PC7, PB0–PB7, PA0–PA7 | GPIO pins with alternate functions | Configurable as digital I/O or mapped to UART0/1, SSI0, I²C0, timer inputs/outputs, and comparator inputs - enables flexible board-level signal routing. |
| XTAL, XTAL1, XTAL2 | Clock oscillator terminals | Supports external crystal (4–25 MHz) or ceramic resonator - used to drive system clock via PLL for stable 50 MHz operation. |
| nRST | Active-low reset input | Asynchronous reset assertion clears CPU state and peripherals - requires external pull-up and debounced source for reliable startup. |

FAQ
What is the maximum operating frequency of the LM3S600-EQN50-C2?
The LM3S600-EQN50-C2 operates at a maximum system clock frequency of 50 MHz, achieved using the internal PLL driven by an external crystal (4–25 MHz) or precision internal oscillator. This frequency is specified across the full industrial temperature range (–40°C to +85°C) and supported by the ARM Cortex-M3 core's timing closure in the LQFP-50 package.
Does the LM3S600-EQN50-C2 include an analog-to-digital converter (ADC)?
No, the LM3S600-EQN50-C2 does not include an ADC. It features two analog comparators with internal voltage reference options (1.65 V or 2.5 V), but no successive-approximation or sigma-delta ADC circuitry. For designs requiring digitized analog measurements, TI recommends the pin-compatible LM3S610-EQN50-C2, which adds a 10-bit 8-channel ADC.
What debug interface does the LM3S600-EQN50-C2 support?
The LM3S600-EQN50-C2 supports JTAG debugging via dedicated TCK, TMS, TDI, TDO, and nTRST pins. It is fully compatible with TI's ICDI-based debug tools (e.g., Stellaris LaunchPad, SmartRF Studio) and third-party ARM debug probes supporting ARM CoreSight SWD/JTAG protocols.
Is the LM3S600-EQN50-C2 RoHS compliant and halogen-free?
Yes, the LM3S600-EQN50-C2 is RoHS compliant and halogen-free per TI's published environmental compliance documentation (SPMS099I datasheet, Section 16). It meets JEDEC J-STD-609A Class 1 for moisture sensitivity and is rated for MSL-3 handling prior to reflow soldering.
What is the flash endurance and data retention specification for the LM3S600-EQN50-C2?
The LM3S600-EQN50-C2 flash memory is rated for a minimum of 10,000 erase/write cycles and guarantees data retention for 20 years at 85°C or 40 years at 25°C ambient, as specified in TI's SPMS099I datasheet Section 17.1.6. These values apply under recommended operating conditions and proper programming sequence adherence.
