RF Chip

Op de chip hebben ze een klodder hars gegooid, wellicht om niet te kunnen achterhalen welke chip het is (??), met wat werk, kan je het eraf krabben, we zien dan de chip:

RFPIC12F675

Microchip PIC 12F675F (1k FLASH, 380 – 450 MHz ASK/FSK transmitter, SOIC-20)

The RFPIC12F675 devices pack Microchip’s powerful yet easy-to-program PICmicro® microcontroller architecture and a 434MHz ASK/FSK RF transmitter into a 20-pin package. In addition, it features a 4 channel 10-bit Analog-to-Digital (A/D) converter, one Comparator channel, and 128 bytes of EEPROM memory. The devices offer field re-programmability, small package outline, and low external component count to fit the most space-constrained applications.

  • 128 bytes of EEPROM Data Memory
  • Programmable pull-up resistors
