Wirelessc PIC microcontroller simplifies secure remote keyless entry designs
The PIC12LF1840T48A is the first in a family of single-chip devices that integrate an eXtreme Low Power (XLP), 8-bit PIC microcontroller with a sub-GHz RF transmitter. The integration in a single, 14-pin TSSOP package makes it ideal for space-, power- and cost-constrained applications, such as remote keyless entry fobs for automobiles, garage doors and home security systems, as well as a broad range of other home and building automation systems. The device is also optimised to run Microchip’s royalty-free KEELOQ code-hopping technology, a proven security technology used worldwide by leading manufacturers.
In addition to secure wireless communication, the PIC12LF1840T48A is designed to maximise battery life via an extremely low operating voltage of 1.8V. Furthermore, the XLP microcontroller has extremely 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.
Samples are available today, and volume production is expected in January.
