Microchip's PIC12LF1840T48 8-Bit Flash MCU with RF Transmitter is aptly
suited to operate in highly constrained environments where the available
energy resources are scarce and long battery life is highly desirable.
This device combines a low power Flash microcontroller with a wireless
enabling RF transmitter, into a single 14‑pin package. This streamlined
packaging helps designers solve both their power consumption and product
footprint problems within one feature rich device. The PIC12LF1840T48A
is ideal for developing low cost and extremely low power wireless
applications such as remote keyless entry (automotive, garage doors),
security systems (alarm keypads, access control, wireless security
sensors) or remote monitoring.
