The FT61F132A-RB is a 14-pin Other Processors and Microcontroller (MCU) SOP-14 RoHS manufactured by Fremont Micro Devices. It is a one-time programmable 8-bit microcontroller with an internal oscillator. It has 13-IO lines, 9 of which can be individually configured as input, output, or interrupter. It is powered by a 3V to 5.5V voltage range, with a maximum operating current of 50mA. It features 112 programmable memory bytes, including 8K of FLASH program memory, 128B RAM, a 16-bit timer, and a watchdog timer. It also provides a VCC voltage monitor, which provides an interrupt-driven system reset when the input voltage falls below the safe operational level.
