It has 256 KB of Flash and 64 KB of RAM. On the connectivity side, this part integrates both Ethernet MAC+PHY and CAN bus — a pairing that lets a single MCU bridge an industrial CAN network to a plant Ethernet backbone. The 42 general-purpose I/O and the 4-channel 10-bit ADC cover local sensor read and actuator drive without an external CPLD. At 50 MHz the Cortex-M3 executes a single-cycle multiply and a hardware divide, so a PID loop or a CAN message filter runs in deterministic time. The 64 KB of RAM is sized for a small RTOS with a few mailboxes — not a Linux-class heap, but adequate for a motor-drive state machine or a protocol gateway that handles one or two concurrent connections. This device is flagged as end-of-life (hot). Production has stopped or is in its final window. For a BOM that depends on this part, the procurement path is surplus and broker-channel sourcing.","metaTitle":"LM3S8962-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, Ethernet +","metaDescription":"Texas Instruments LM3S8962-EQC50-A2 Stellaris ARM Cortex-M3 MCU. 50 MHz core, 256 KB Flash, 64 KB RAM, Ethernet & CAN.

Production has ceased or is in its final phase. For new builds, source surplus inventory through independent distribution; for legacy BOMs, plan a last-time buy or a pin-compatible migration."},{"question":"Does LM3S8962-EQC50-A2 have Ethernet and CAN bus?","answer":"Yes, this MCU integrates both Ethernet and CAN bus controllers, along with I²C, SPI, SSI, UART/USART, and IrDA. The Ethernet MAC+PHY and CAN controller share the same die, so a single chip can bridge an industrial CAN network to an Ethernet backbone."},{"question":"What is the package and pin count of LM3S8962-EQC50-A2?","answer":"It comes in a 100-LQFP (14x14 mm) surface-mount package with 42 general-purpose I/O pins.
