Product details

50 MHz Cortex-M3 — processing headroom for control and comms

The ARM Cortex-M3 core runs at 50 MHz, delivering enough throughput for real-time control loops, protocol parsing (UART, SPI, SSI, IrDA), and moderate data processing without external memory.

The 57 I/O lines, 3x10-bit ADC channels, and built-in brown-out detect, POR, PWM, and WDT peripherals reduce external component count.

Package and footprint — 100-LQFP

Frequently asked questions

What is the replacement for LM3S1332-EQC50-A2T?

The manufacturer has not published a direct successor order code for this specific variant. Within the Stellaris ARM Cortex-M3S 1000 series, there are pin-compatible siblings with different memory and peripheral configurations — a cross-reference search against the base product number LM3S1332 may yield a form-fit-function alternate. For a confirmed second source, submit an RFQ with your required memory and I/O profile.

Does LM3S1332-EQC50-A2T have built-in ADC?

Yes, it includes a 3-channel 10-bit ADC (A/D 3x10b). This is sufficient for reading analog sensors, potentiometers, or current-sense signals in industrial control applications.
