Product overview

74HC139DThe 74HC139D is a microcontroller unit based on a high-performance ARM®Cortex®-M432 bit RISC kernel, operating at frequencies up to 168MHz. The Cortex-M4 kernel has floating-point unit (FPU) single precision and supports all ARM single precision data processing instructions and data types. It also implements a full set of DSP instructions and memory protection units (MPUs) to enhance application security. All devices offer three 12-bit ADCs, two Dacs, one low-power RTC, twelve general-purpose 16-bit timers, including two PWM timers for motor control, and two general-purpose 32-bit timers.
