STM8SPLNB1M6

Overview

The STM8SPLNB1M6 is an 8-bit microcontroller dedicated to DiSEqC slave operation in SaTCR-based LNBs and switchers. It provides a complete hardware and firmware solution for implementing LNB device control according to the Digital Satellite Equipment Control standard. The device features clock, reset, and supply management with reduced power consumption and safe power on/off handling via a low voltage detector (LVD). It operates within a 2.95 V to 5.5 V supply range and includes an internal 16 MHz oscillator.

Feature Summary

• Dedicated DiSEqC slave microcontroller for SaTCR based LNBs and switchers
• Complete hardware and firmware solution for DiSEqC protocol decoding
• Internal 16MHz oscillator with low voltage detector (LVD) for safe power management
• Two DiSEqC communication interfaces and four I2C communication I/O ports

Applications

• DiSEqC slave operation in SaTCR based Low Noise Block (LNB) converters
• Satellite signal switching systems requiring DiSEqC compliance
• Legacy matrix control applications using dedicated output pins

Procurement Notes

Verify the specific suffix 'M6' against official STMicroelectronics documentation to confirm package type and temperature grade. Ensure the component is sourced from authorized distributors to guarantee authenticity. Check for active status and end-of-life notifications prior to procurement.

Selection Notes

Select this component when a pre-programmed hardware and firmware solution for DiSEqC slave operation is required. It is suitable for designers needing an implementation overview of LNB device control without developing custom firmware. Consider the 2.95 V to 5.5 V operating voltage range for compatibility with satellite receiver power supplies.

Part Context

The STM8SPLNB1M6 belongs to the STM8S application-specific line, which offers solutions for analog performance and DiSEqC applications. This line is part of the broader STM8 8-bit MCU platform manufactured using ST's proprietary embedded non-volatile memory technology. The PLNB1 variant is specifically optimized for dish-head control rather than general-purpose computing.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should verify pinout and firmware compatibility if considering alternative DiSEqC controllers from other manufacturers.
