Microchip PIC12LF1840T48A Integrates XLP PIC MCU with Sub-GHz RF Transmitter

Microchip Technology introduced their PIC12LF1840T48A single-chip devices. The PIC12LF1840T48A integrates an eXtreme Low Power (XLP), 8-bit PIC microcontroller with a sub-GHz RF transmitter. The Microchip PIC12LF1840T48A is optimized to run Microchip’s royalty-free KEELOQ advanced code-hopping technology. The new device family is available in a 14-pin TSSOP package. It is priced at $1.06 each in 10,000-unit quantities. Samples are available now. Volume production is expected in January.

Microchip Technology PIC12LF1840T48A transmitter with integrated microcontroller

The Microchip PIC12LF1840T48A is designed to maximize battery life via an extremely low operating voltage of 1.8V. In addition, the eXtreme microcontroller has extremely low sleep current consumption. The XLP microcontroller 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.

The PIC12LF1840T48A is optimized for secure wireless communication. It is 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.
