Product details

50 MHz core — what it means for the bus

Obsolete — sourcing reality

The LM3S1N11-IQC50-C3 is officially obsolete. No direct pin-compatible replacement is listed in the available documentation. For production fills or repair spares, this part is sourced through independent distribution channels — quoted to order against an RFQ with availability and current pricing confirmed at quote time.

Peripheral set and connectivity

On-chip peripherals include brown-out detect, DMA, POR, PWM, and watchdog timer. The connectivity block supports I²C, IrDA, LINbus, Microwire, SPI, SSI, and UART/USART — enough for mixed-protocol industrial buses and sensor interfaces. The 8-channel 10-bit ADC covers analog inputs like potentiometers, thermistors, or current-sense resistors without an external converter.

Frequently asked questions

Is LM3S1N11-IQC50-C3 obsolete?

Yes, the LM3S1N11-IQC50-C3 is obsolete. No official successor or pin-compatible replacement is listed. Sourcing is via independent distribution against an RFQ.

What is the replacement for LM3S1N11-IQC50-C3?

No official replacement part number is documented. For a drop-in alternative, a design review of the Stellaris family or a migration to a current Cortex-M3/M4 MCU with similar peripheral mapping is recommended. Sourcing the original part through surplus channels remains an option.
