Frequently Asked Questions
What processor core and maximum clock does LM3S9D90-IQC80-A2 use?
LM3S9D90-IQC80-A2 is based on the 32-bit ARM Cortex-M3 core and can be clocked up to 80 MHz, providing deterministic interrupt latency and Thumb-2 instruction efficiency for demanding industrial control workloads.
How many I/O lines are available on LM3S9D90-IQC80-A2 for peripheral connectivity?
The device exposes 72 configurable GPIO lines in a 100-pin LQFP package. These pins can be multiplexed to UART, SPI, I2C, and CAN peripherals, enabling multi-bus industrial control boards without external I/O expanders.
Does LM3S9D90-IQC80-A2 include analog signal acquisition capability?
Yes, an integrated 12-bit ADC supports multi-channel analog signal acquisition. Combined with DMA channels, it allows background data transfers at up to 1 Msps without stalling the CPU during continuous sensor sampling.
When would LM3S9D90-IQC80-A2 be preferred over a smaller LM3S family member?
It is the preferred choice when a design requires more than 50 I/O lines, boundary scan for production test, or simultaneous multi-channel DMA transfers—capabilities absent from smaller LM3S variants in 64-pin packages.
