The ST7FLITEU09B3 is a highly-integrated, low-power 8-bit microcontroller from STMicroelectronics, designed to offer an optimal mix of performance and cost-effectiveness for a wide range of applications. This MCU is part of the ST7 family and is tailored for use in automotive, industrial, and consumer applications where reliable operation under harsh conditions is a prime requirement.

Key Features

• Core: An efficient 8-bit CPU providing high processing power with a maximum external clock frequency of 8 MHz, which can be internally multiplied up to 16 MHz using the onboard PLL (Phase-Locked Loop).
• Memory: The device comes with 8 Kbytes of Flash program memory, offering endurance of up to 100,000 write/erase cycles, and 128 bytes of true data EEPROM with up to 300,000 cycles. This non-volatile memory is perfect for applications that require frequent or on-the-fly firmware updates.
• I/O Ports: 10 multifunctional bidirectional I/O lines, 10 high sink outputs, and an integrated analog comparator enhance the versatility of the device, making it suitable for a variety of control and sensing tasks.
• Timers: An 8-bit timer with a 7-bit prescaler and an additional watchdog timer help in managing time-critical operations and system integrity checks.
• Communication: A synchronous serial communication (SPI) interface for fast data transfers and an I2C interface for multi-master communications.
• Power Management: Low-power modes, including Halt and Active-Halt, help reduce power consumption when the MCU is not in full operation.
• Operating Conditions: The device operates over a wide temperature range from -40°C to 85°C and has a 3.3V to 5.5V supply voltage range, making it robust against environmental variations.
