It carries 256 KB of Flash and 128 KB of RAM — enough headroom for a DSP filter bank, a Modbus TCP stack, or a motor-control loop with FOC. The 144-LQFP package gives you 114 I/O, so you are not pin-limited on a multi-peripheral board. On-chip peripherals include CANbus, USB OTG, SPI, I²C, and SPDIF-Rx, which makes this part a natural fit for an industrial controller or an audio interface that needs to talk to a PLC and a codec on the same die. This part carries an EOL-hot lifecycle status. That means the manufacturer has announced end-of-life — last-time-buy windows are closing or closed. For a BOM line, that is the signal to qualify a replacement or secure a bridge buy. The base product number is STM32F446, so pin-compatible siblings in the same family (different Flash/RAM or temperature grade) are the first place to look for a swap.","metaTitle":"ST STM32F446ZCT6JTR ARM Cortex-M4 MCU, 180MHz","metaDescription":"STMicroelectronics STM32F446ZCT6JTR 32-bit ARM Cortex-M4 MCU, 180MHz, 256KB Flash, 128KB RAM, 114 I/O, -40 to 85°C, 144-LQFP.
