STM8L152R6T6

Microcontrollers Overview

The STM8L152R6T6 is an ultra-low-power 8-bit microcontroller from STMicroelectronics, featuring the enhanced STM8 CPU core with up to 16 MIPS performance at a maximum frequency of 16 MHz. It integrates 32 Kbytes of Flash program memory and includes embedded data EEPROM for non-volatile storage. The device operates within a supply voltage range of 1.65 V to 3.6 V without Brown-out Reset (BOR), or 1.8 V to 3.6 V with BOR enabled. It supports five low-power modes, including Halt mode consuming as low as 400 nA, and offers fast wake-up capabilities. The MCU incorporates a comprehensive peripheral set suitable for battery-powered applications.

Microcontrollers Procurement Notes

Verify the specific suffix T6 indicates tape and reel packaging when sourcing components. Confirm the operating temperature grade matches the application environment, as variants exist for different thermal ranges. Ensure compatibility with the 1.65 V to 3.6 V supply voltage window if Brown-out Reset functionality is not utilized in the design. Cross-reference the exact part number against manufacturer datasheets to confirm pinout and package dimensions before integration.

Microcontrollers Selection Notes

Select this component for designs prioritizing low energy consumption alongside moderate processing power. The STM8L152R6T6 is suitable where 32 Kbytes of Flash and integrated EEPROM are sufficient. Consider the available I/O count and peripheral mix, such as the 12-bit ADC and dual DACs, against system requirements. Evaluate the need for the SWIM debug interface during development phases. Compare against other STM8L series members if higher memory density or additional pins are required.

Microcontrollers Part Context

This microcontroller belongs to the STM8L15xx6/8 family, representing the high-density and medium+ density segments of the STM8L ultra-low-power line. It shares architectural similarities with other STM8L families, facilitating migration between different product lines using common development tools. The device leverages a proprietary ultra-low-leakage process technology to achieve its power efficiency targets while maintaining robust performance characteristics.

Microcontrollers Replacement Considerations

Direct substitutes within the same package and pinout include other STM8L152R6 variants with different temperature grades or packaging options. Upgrades to higher memory densities may require checking pin compatibility, such as moving to STM8L152R8 models. Verify that any replacement maintains the required 16 MHz clock speed and peripheral availability.
