Product details

It is designed for industrial control, motor drive, and CAN-bus gateway applications where a single-core processor with moderate memory and rich connectivity is needed.

Connectivity and peripheral set — sizing the I/O budget

The 8-channel 12-bit ADC (8x12b) handles analog sensor inputs without an external converter.

Package and temperature grade — design-in checklist

Housed in a 64-LQFP (10x10 mm) package, the LM3S5G36-IQR80-A2T uses a standard 0.5 mm pitch footprint that is straightforward to route on a two-layer board. Supply voltage is 3.0 V to 3.6 V, compatible with common 3.3 V rail designs.

Frequently asked questions

What is the replacement for LM3S5G36-IQR80-A2T?

If a design requires a pin-compatible alternate, a review of the Stellaris M3S 5000 series family would be needed — but no direct drop-in substitute is documented.

What package is LM3S5G36-IQR80-A2T?

The LM3S5G36-IQR80-A2T is supplied in a 64-LQFP (10x10 mm) package with a 0.5 mm pitch.

What is LM3S5G36-IQR80-A2T's listed speed?

The core is rated at 80 MHz, which is the maximum clock frequency for the ARM Cortex-M3 processor in this device.
