OL2361 Sigfox Tx Modem

The OL2361 is a high-performance single chip embedded sub-GHz RF transmitter with up to +10 dBm output power for Sigfox applications requiring an RF transmitter.

• The embedded microcontroller and memory are reserved for specific Sigfox binaries provided by NXP
• There are two firmware variants available, whereby one is dedicated for NXP's Sigfox RFID tag reference design, and the second allows the OL2361 to be connected to a host microcontroller that will run the application. In the latter case, the connection between host and OL2361 is established via SPI
• The on-chip UHF transmitter requires no external components to operate from 868 MHz to 928 MHz except for a single 27.6 MHz reference crystal and the loop antenna matching circuitry
• The device features up to 8 I/O port lines allowing for up to 8 command button inputs while one line is multiplexed additionally with a LED driver functionport
• The OL2361 provides 2 kByte of Ultra Low Power Serial EEPROM with access control as defined by the application, 1 kByte of RAM and up 16 kByte EROM (FLASH like) for the application code
• The device comes in tiny 24 pin HVQVN package that consumes only 16 mm² of board space enabling ultracompact designs
