Frequently Asked Questions
What core speed and memory does LM3S9790-IQC80-C0T offer for industrial networking designs?
The LM3S9790-IQC80-C0T runs an ARM Cortex-M3 core at up to 80 MHz and provides 256 KB Flash plus 96 KB SRAM, giving designers enough headroom for a full TCP/IP stack alongside application firmware without external memory.
How does the integrated Ethernet MAC/PHY in LM3S9790-IQC80-C0T reduce BOM cost versus competing MCUs?
By embedding a 10/100 Ethernet MAC and PHY on-chip, the LM3S9790-IQC80-C0T eliminates an external PHY IC that typically costs 1 USD to 3 USD, reduces PCB routing complexity, and lowers current draw to under 50 mA for the network block.
Which communication buses does LM3S9790-IQC80-C0T support for multi-protocol embedded systems?
It supports 10/100 Ethernet with integrated PHY, USB 2.0 OTG, dual CAN 2.0B at up to 1 Mbps, multiple UART, SSI, and I2C interfaces, enabling a single device to bridge field-bus and IP networks in industrial controllers.
For what package footprint must a PCB be designed to accommodate LM3S9790-IQC80-C0T?
The device comes in a 108-pin LQFP package with a 0.5 mm pitch, requiring a PCB footprint of approximately 12 mm x 12 mm, which is manageable on standard 4-layer FR4 boards used in industrial controller designs.
