Mainstream Mixed signals MCUs ARM Cortex-M4 core with DSP and FPU, 64 Kbytes Flash, 72 MHz CPU, CCM, 12-bit ADC 5 MSPS, comparators, op-amp

The STM32F328C8 family is based on the high-performance ARM 32-bit Cortex-M4 RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU). The STM32F328C8 family incorporates high-speed embedded memories(up to 64 Kbytes of Flash memory, 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32F328C8 devices offer up to two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a low-power RTC, one general-purpose 32-bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers. They also feature standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.

The STM32F328C8 family operates in the –40 to +85 °C and –40 to +105 °C temperature ranges from 1.8 V +/-8% power supply. A comprehensive set of power-saving mode allows the design of low-power applications.

The STM32F328C8 family offers devices in 48-pin packages.
