72 MHz ARM Cortex-M3 with 288 KB flash in a 48-LQFP
The CY9BF124KPMC-G-MNE2 is a 32-bit single-core ARM Cortex-M3 microcontroller from the Infineon FM3 MB9B120M series, clocked at 72 MHz. The 288 KB on-chip flash and 32 KB RAM provide enough code and data space for a real-time control loop with moderate sensor fusion — think a motor drive with current-sense feedback or a multi-axis pump controller.
Supply range and temperature grade for industrial deployment
On-chip peripherals include DMA, LVD, POR, PWM, and WDT — the watchdog and brown-out reset eliminate external supervisor ICs for most applications. The 14-channel 12-bit ADC and 2-channel 10-bit DAC handle analog sensor inputs and control outputs without an external converter. Connectivity options — CSIO, I²C, LINbus, and UART/USART — cover the common serial buses for industrial sensors, HMI panels, and actuator interfaces. The internal oscillator reduces BOM count for applications that do not require a precision external clock.
Active lifecycle and compliance posture
ROHS3 compliance (EU 2015/863) is confirmed, covering the full ten restricted substance categories without exemption.
