Frequently Asked Questions
What is the maximum clock speed of LM3S9B95-IQC80-C0T, and does it include an FPU?
The LM3S9B95-IQC80-C0T ARM Cortex-M3 core operates at up to 80 MHz. The Cortex-M3 architecture does not include a hardware floating-point unit (FPU), so floating-point operations are handled in software. For 80 MHz integer and fixed-point DSP workloads, performance is well-suited to industrial control loops and communication stack processing.
Does LM3S9B95-IQC80-C0T have an integrated Ethernet PHY, and what is the supported data rate?
Yes, the LM3S9B95-IQC80-C0T integrates a full 10/100 Mbps Ethernet MAC and PHY on-chip, eliminating the need for an external PHY device. The integrated Ethernet block supports both 10BASE-T and 100BASE-TX, reducing BOM cost and PCB routing complexity in networked industrial control applications compared to using a separate PHY such as the LAN8720.
How much on-chip flash and SRAM does LM3S9B95-IQC80-C0T provide for embedded firmware?
The LM3S9B95-IQC80-C0T includes 256 KB of on-chip flash for program storage and 96 KB of SRAM for data and stack. This memory configuration supports mid-complexity RTOS-based firmware including TCP/IP stacks, USB device class drivers, and CAN protocol stacks simultaneously, without requiring external memory in typical industrial gateway applications.
Which communication peripherals are integrated in LM3S9B95-IQC80-C0T for industrial bus connectivity?
The LM3S9B95-IQC80-C0T integrates 10/100 Ethernet, USB OTG (host and device at 12 Mbps Full Speed), 2 CAN controllers, 3 UART ports, 2 I2C, and 4 SSI/SPI interfaces. This comprehensive peripheral set allows the device to serve as an industrial gateway connecting CAN field devices to an Ethernet network while also supporting USB-based configuration and data upload.
