Obsolete — last-time-buy reality

No official successor part number appears in the record. For production runs still locked to this BOM line, the only channel is independent distribution — we source verified stock from our broker network. Each unit is quoted to order, with date codes and condition confirmed before shipment.

A/D converter and I/O count

Sixteen 10-bit ADC channels are integrated, enough for multi-sensor feedback in a motor-drive or power-monitoring application.

Frequently asked questions

Is LM3S5951-IQC80-C1 obsolete?

Yes. There is no direct pin-compatible replacement listed; a new design should evaluate the Tiva C Series (TM4C123/129) or a comparable Cortex-M4 MCU.

Does LM3S5951 support USB OTG?

Yes.

What is the price of LM3S5951?

Pricing is market-driven and varies with quantity, date code, and condition. Submit an RFQ for a current quote; we source from multiple independent inventories and can offer competitive pricing for this obsolete part.
