This makes the MCU suitable for applications requiring analog measurement and control.

PWM & Timers

The MCU provides up to 7 PWM channels with features including:

• Independent duty-cycle control
• Configurable polarity
• Capture/compare/PWM functionality
• Complementary PWM outputs
• Dead-time control
• Center-aligned and edge-aligned operation
• One-shot operation
• Automatic fault/brake functions

The integrated timers include a 16-bit Watchdog Timer, 16-bit Timer1, 16-bit Timer2, and 8-bit Timer4.

Communication Interfaces

The FT64E0A5 integrates several serial communication peripherals:

• SPI
• I²C
• USART1
• USART2

This allows the device to interface with sensors, displays, EEPROMs, motor-control peripherals, communication modules, and other digital devices.

Integrated Analog Features

In addition to the ADC, the device integrates an operational amplifier with offset calibration capability. The amplifier output can be routed to an I/O pin or ADC input, making the MCU suitable for basic analog signal-conditioning applications.

Power & Programming

The FT64E0A5 can operate from a wide supply range suitable for both low-voltage and 5 V embedded systems.
