Integrates Ethernet MAC and PHY, I²C, SPI, UART, SSI, and a 16-channel 12-bit ADC. The 80 MHz Cortex-M3 delivers enough throughput to run a lightweight TCP/IP stack and a real-time control loop without an external host processor. The 512 KB Flash holds a full application image plus a bootloader for field updates over Ethernet; the 64 KB SRAM provides packet buffers and variable storage — adequate for moderate data logging but tight for heavy web-server content. The 16-channel 12-bit ADC captures analog sensor inputs directly, reducing external ADC count. ## Obsolete — sourcing through the independent channel Marked obsolete by the manufacturer. No last-time-buy window remains; supply is through the independent surplus and broker market. We source and quote to order against an RFQ.","metaTitle":"Texas Instruments LM3S6C65-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S6C65-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 64 KB SRAM, Ethernet, -40°C to 85°C.
