Product details

Cortex-M4 with 72 MHz and a 40-channel ADC bank

The distinguishing feature for mixed-signal designs is the analog front end: 40 multiplexed 12-bit ADC channels and two 12-bit DACs, which lets this single chip handle multi-axis current sensing or multi-channel data acquisition without an external ADC multiplexer.

115 I/O and peripheral mix — what the pin count buys you

With 115 I/O lines brought out to the 144-LQFP package, this part can drive a parallel LCD data bus, a bank of optocoupled inputs, and still leave room for the usual CAN, I²C, SPI, and UART interfaces.

That means no last-time-buy deadline to manage, no PCN-driven scramble for an alternate source.

Frequently asked questions

What is the difference between STM32F303ZDT6 and STM32F303VCT6?

The STM32F303VCT6 is a 100-pin LQFP variant of the same STM32F303 family, versus the 144-pin LQFP on the ZDT6. The VCT6 offers fewer I/O (up to 87 vs 115) and a smaller package footprint. Both share the 72 MHz Cortex-M4 core, 384 KB Flash, and the 40-channel ADC bank, so firmware porting between them is straightforward if you adjust the pin mapping.
