Product details

The STM32F091CCT6J: ARM Cortex-M0 core at 48 MHz, 256 KB Flash, 32 KB RAM, 13x12b ADC, 2x12b DAC, CAN, I²C, SPI, UART/USART.

STMicroelectronics lists the STM32F091CCT6J as obsolete. No last-time-buy window or official successor is recorded in the available lifecycle data. That means each procurement lot should be inspected for date code consistency and traceability, and the per-unit cost will reflect scarcity rather than factory pricing.

Frequently asked questions

Is STM32F091CCT6J obsolete?

Yes, STMicroelectronics has marked the STM32F091CCT6J as obsolete. No last-time-buy or successor part number is recorded in the available lifecycle data. For production continuity, evaluate a pin-compatible alternate within the STM32F0 family or source through independent surplus channels.

What are the specifications of STM32F091CCT6J?

It integrates a 13-channel 12-bit ADC, two 12-bit DACs, and connectivity including CAN, I²C, SPI, and multiple UART/USART interfaces.
