ST7FLITEU09B6

Microcontrollers Overview

The ST7FLITEU09B6 is an 8-bit microcontroller from the ST7LITE family, featuring a single-voltage Flash program memory of 2K bytes and 128 bytes of RAM. It includes 128 bytes of data EEPROM with high endurance. The device integrates a 5-channel 10-bit ADC, two timers (one 8-bit and one 12-bit), and multiple I/O lines. Operating within a voltage range of 2.4V to 5.5V, it supports internal RC oscillators up to 8MHz and offers five low-power modes.

Microcontrollers Feature Summary

• Integrates a 10-bit analog-to-digital converter with five input channels for precise signal acquisition.
• Features dual timer units including an 8-bit watchdog/real-time clock timer and a 12-bit PWM timer.
• Supports in-circuit programming and in-application programming via a single-voltage Flash memory interface.
• Includes hardware low-voltage detection and auxiliary voltage detection for robust power management.

Microcontrollers Applications

• Cost-sensitive lighting systems
• Home appliances and white goods
• Alarm systems
• Air conditioning controllers

Microcontrollers Procurement Notes

Verify the specific suffix B6 against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as ST7Lite products may be subject to discontinuation notices. Ensure design-in compliance with RoHS directives by checking the latest environmental declaration. Cross-reference pinouts if replacing legacy components.

Microcontrollers Selection Notes

Select this component when a balance of moderate processing power and low cost is required. The integrated 10-bit ADC and dual timers make it suitable for applications needing basic analog sensing and timing control without external peripherals. Consider the 2KB Flash limit for complex firmware requirements.

Microcontrollers Part Context

This part belongs to the ST7LITE series, designed for ultra-low-cost embedded applications. It utilizes the standard ST7 core architecture known for efficient code density. The U09 variant specifically denotes the memory configuration and peripheral set within the Lite family, targeting consumer electronics where bill-of-materials cost is critical.

Microcontrollers Replacement Considerations

Check for direct substitutes within the ST7FLITEUxx series with compatible memory sizes. Verify pin compatibility if moving between SOP and other packages. Review any Product Change Notices regarding obsolete ST7 models for recommended migration paths.
