Product details

What this STM32F101ZET6 brings to a 144-LQFP footprint

It comes in a 144-pin LQFP package, giving you 112 I/O lines for peripheral-rich control boards — motor drives, PLC I/O banks, or industrial HMI panels.

At 36 MHz, the Cortex-M3 core runs code from Flash with a single wait state after the first access. If your algorithm needs more throughput, the STM32F103 sibling runs at 72 MHz, but this part's 36 MHz keeps power and EMI lower for designs that don't need the extra speed.

No last-time-buy notice, no EOL watch.

Frequently asked questions

Is STM32F101ZET6 compatible with STM32F103ZET6?

The STM32F101ZET6 and STM32F103ZET6 share the same 144-LQFP footprint and pinout, but the F103 runs at 72 MHz and includes a USB interface and additional timers. The F101 is the cost-optimized value-line variant — pin-compatible for a board spin, but check the peripheral set if your firmware depends on USB or the extra timer channels.
