ST7 - 8-bit Microcontrollers - ST7LNB

ST7LNB : Specific for terrestrial satellite dish LNB heads and switchers
STMicroelectronics’ ST7LNBx series devices are application-specific standard microcontrollers developed for terrestrial satellite equipment using the DiSEqC™ (digital satellite equipment control) communication protocol.
Defined by the EUTELSAT (European telecommunication satellite) ‘Slave Microcontroller’ Specification 1.0, the ST7LNBx series is pre-programmed to decode DiSEqC signals from/to the TV set-top box.
Standard versions offer default software configuration values while customer dedicated versions are developed on demand and are customized with specific customer option bytes.
  Features   Benefits
Fully-compliant with DiSEqC slave microcontroller specification version 1.0 Suitable for all applications requiring DiSEqC communication protocol decoding
Supports all DiSEqC versions (toneburst, 1.x protocol, ready for 2.1 bidirectional communication) Design upgradability and flexibility for future requirements
Excellent analog-to-digital cell performance Direct 22KHz signal input with reduced number of external components
Excellent accuracy (1%) of embedded clock source Excellent accuracy of data decoding
20 years data retention at 55°C Perfectly suited to satellite digital equipment environment
EEPROM programming service Flexibility and ability to customize software to specific application requirements and configurations
