If your existing design uses 3.3 V peripherals, you will need level translation on the I2C and UART lines, or a separate 1.8 V regulator just for this MCU. ## Peripheral set and package On-chip peripherals include LCD drive, low-voltage detect (LVD), power-on reset (POR), PWM timers, and a watchdog timer (WDT) — a typical set for a general-purpose industrial MCU. The 67 I/O lines are available in a surface-mount package, though the exact package code (the 'MPMC' suffix) should be verified against the mechanical drawing for footprint compatibility. The part is, not tape-and-reel, so factor in hand-loading or tube-feeding for your pick-and-place setup.","metaTitle":"MB9AFA32MPMC-G-SNE2 Cypress FM3 ARM Cortex-M3 MCU, 20 MHz","metaDescription":"MB9AFA32MPMC-G-SNE2 Cypress FM3 ARM Cortex-M3 MCU, 20 MHz, 1.8 V supply, -40°C to 85°C, 67 I/O, FLASH.
