Microchip’s new 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 IC’s combination of features in a single, 14-pin TSSOP package makes it suitable 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 thanks to a low operating voltage of 1,8 V. 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.
