Frequently Asked Questions
What is the maximum clock frequency of the LM3S300-EGZ25-C2, and which CPU core does it use?
The LM3S300-EGZ25-C2 runs an ARM Cortex-M3 core at up to 25 MHz, delivering deterministic 32-bit processing for real-time embedded control tasks. This clock rate is sufficient for sensor processing loops, PWM generation, and UART/SPI communication protocols in industrial systems.
How many I/O lines does the LM3S300-EGZ25-C2 provide, and what package does it use?
The device provides 36 configurable I/O lines and is housed in a 48-pin QFP package. The LQFP-48 package with a 7 mm × 7 mm body footprint suits compact PCB designs where board area is limited and through-hole components are undesirable.
Which embedded control applications benefit most from the LM3S300-EGZ25-C2 integrated ADC?
Applications such as temperature monitoring systems, pressure sensor interfaces, and motor current-sense circuits benefit from the on-chip ADC because analog signals up to the supply rail can be sampled without an external 12-bit ADC IC. This reduces BOM cost and PCB trace length, improving noise immunity in industrial environments.
When is the LM3S300-EGZ25-C2 a suitable alternative to an 8-bit microcontroller in a cost-sensitive design?
The LM3S300-EGZ25-C2 is a suitable upgrade from an 8-bit MCU when the application needs 32-bit arithmetic, more than 8 I/O lines, or an integrated ADC with at least 8 channels, yet the board must stay under 50 mm². The Cortex-M3 executes many operations in 1 cycle versus 4–12 cycles on a typical 8-bit core, improving throughput without increasing supply voltage beyond 3.3 V.
