ST STM8SPLNB1M6

The STM8SPLNB1 is an 8-bit microcontroller dedicated to DiSEqC slave operation in SaTCR based LNBs (Low Noise Block) and switchers. It is a complete hardware and firmware solution for system designers who require an implementation overview of the LNB device control according to DiSEqC standard (Digital Satellite Equipment Control). STM8SPLNB1 device is receiving DiSEqC signal on the coaxial cable, decoding and processing the DiSEqC commands. As a result, legacy matrix or |²C lines are controlled. The STM8SPLNB1 device can also send DiSEqC answer back to master through coaxial cable. STM8SPLNB1 is designed for usage with LNB devices with |²C bus control and/or direct pins control. Behavior of STM8SPLNB1 devices can be modified through a set of configuration parameters which are stored in device data EEPROM memory. Configuration is done also through specific DiSEqC commands. After final configuring the device can be locked to given configuration (vendor config)

• Clock, reset and supply management – Reduced power consumption, Safe power on/off management by low voltage detector (LVD), 2.95 to 5.5 V operating voltage, Internal 16MHz oscillator.
• Communication interface – Two DiSEqC communication interfaces, Four |²C communication interfaces I/O ports.
• 4 output pins for control of a legacy matrix.
