Microchip announces the PIC12LF1840T48A which is the first in a family of single-chip devices that integrate a 8-bit PIC microcontroller with a sub-GHz RF transmitter. The device is optimised to run Microchip’s royalty-free KEELOQ code-hopping technology, a security technology.

In addition to secure wireless communication, the PIC12LF1840T48A is designed to maximise battery life via a low operating voltage of 1.8V. Furthermore, the XLP microcontroller has low sleep current consumption, and is efficiently integrated with the transmitter to enable fast wake-up and send functionality that takes full advantage of the MCU’s 8 MIPS operation.

Application note AN1393 ‘Using the PIC12LF1840T48A Microcontroller with integrated sub-GHz Transmitter’ is available for download.

The PIC12LF1840T48A is available in a 14-pin TSSOP package. Samples are available today, and volume production is expected in January 2012.
