LM3S8733-EQC50-A2

Microcontrollers Overview

The LM3S8733-EQC50-A2 is a 32-bit microcontroller from the Texas Instruments Stellaris family, built on an ARM Cortex-M3 core. It features 128 kB of flash program memory and 64 kB of data RAM. The device operates at a maximum clock frequency of 50 MHz within a supply voltage range of 2.25 V to 2.75 V. It includes an integrated 10/100 MAC PHY for Ethernet connectivity, one CAN channel, four 10-bit ADC channels, and multiple communication interfaces including I2C, SPI, SSI, and UART. The component is housed in a 100-pin LQFP package.

Microcontrollers Feature Summary

• Integrates a 10/100 Ethernet MAC with physical layer transceiver for direct network connection
• Includes Memory Protection Unit (MPU) for enhanced system security and stability
• Supports low-power operation through running, sleep, and deep sleep modes
• Features battery-backed hibernation module for timekeeping during power loss

Microcontrollers Applications

• Industrial control systems requiring Ethernet connectivity
• Building automation and smart metering devices
• Network-enabled sensor nodes
• Embedded controllers with CAN bus requirements

Microcontrollers Procurement Notes

Verify the current lifecycle status before integration, as this component may be designated as not recommended for new designs or obsolete. Confirm that the specific -EQC50 suffix meets all environmental and packaging requirements for your manufacturing process. Ensure compatibility with existing firmware libraries developed for the Stellaris Cortex-M3 architecture.

Microcontrollers Selection Notes

Select this model when both Ethernet MAC/PHY capabilities and CAN interface support are required in a single MCU. It is suitable for applications needing moderate code storage with 128 kB flash and sufficient RAM for complex protocol stacks. Consider the 100-pin LQFP package constraints for PCB layout and thermal management during the design phase.

Microcontrollers Part Context

This part belongs to the Texas Instruments Stellaris LM3S series, which utilizes the ARM Cortex-M3 processor core. The series is designed for cost-sensitive embedded applications requiring high performance and rich peripheral sets. The LM3S8733 variant specifically targets networking applications by combining processing power with onboard Ethernet hardware.

Microcontrollers Replacement Considerations

Check for updated revisions within the LM3S8733 series or cross-reference with other Stellaris models offering similar memory and peripheral configurations. Verify pin-to-pin compatibility if substituting with different package options or newer generations of TI microcontrollers.
