Frequently Asked Questions
What processor core and clock speed does LM3S9792-IQC80-B1 use?
The LM3S9792-IQC80-B1 is built around a 32-bit ARM Cortex-M3 core running at up to 80 MHz, paired with 256 KB of on-chip Flash and 96 KB of SRAM, providing ample compute and memory resources for real-time Ethernet-connected control tasks.
Does LM3S9792-IQC80-B1 include an Ethernet controller, and does it need an external PHY?
Yes, the device integrates a full 10/100 Mbps Ethernet MAC and PHY, meaning no external PHY chip is required. This reduces PCB complexity, BOM cost, and board area compared to solutions that split the MAC and PHY across two ICs.
How many ADC channels are available on LM3S9792-IQC80-B1 and at what resolution?
The LM3S9792-IQC80-B1 provides two independent 12-bit SAR ADC modules with a combined 16 analog input channels and a maximum sample rate of 1 Msps per module, enabling simultaneous multi-channel analog measurement in industrial sensor and monitoring applications.
What package does LM3S9792-IQC80-B1 come in, and what operating temperature range does it support?
The device is housed in a 108-pin LQFP package with an 80-pin variant available. It is rated for industrial operation over -40°C to +85°C, making it suitable for factory-floor and outdoor instrumentation environments where temperature extremes are common.
