LM3S8530-EQC50-A2T

Microcontrollers Overview

The LM3S8530-EQC50-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris family, manufactured by Texas Instruments. It features 96 kB of flash program memory and 64 kB of data RAM. The device operates at a maximum clock frequency of 50 MHz and supports an input/output count of 36 I/O lines. It functions within a power supply voltage range of 2.25 V to 2.75 V and includes interfaces such as CAN, I2C, SPI, SSI, and UART. The component is housed in a 100-LQFP package with an extended industrial temperature rating.

Microcontrollers Feature Summary

• Integrates an on-chip 10/100 MAC Ethernet PHY for direct network connectivity
• Includes a Controller Area Network (CAN) interface for robust communication
• Supports multiple serial communication protocols including I2C, SPI, SSI, and UART

Microcontrollers Applications

• Industrial automation systems requiring CAN bus connectivity
• Networked embedded devices utilizing integrated Ethernet capabilities
• Control units for machinery operating in industrial environments

Microcontrollers Procurement Notes

Verify the specific suffix 'EQC50' against official datasheets to confirm the extended temperature range (-40°C to +105°C), as standard variants may differ. Confirm the 'A2T' designation indicates tape-and-reel packaging if required for automated assembly. Check current lifecycle status, as this model may be discontinued or restricted. Ensure compatibility with existing firmware libraries designed for the Stellaris architecture before procurement.

Microcontrollers Selection Notes

Select this variant when both Ethernet MAC/PHY integration and CAN bus support are required in a single controller. The extended temperature range makes it suitable for harsh industrial conditions where standard commercial parts would fail. Consider the 96 kB memory limit for complex application logic. Verify that the 36 available I/O pins meet the system's peripheral connection requirements.
