Microchip Technology Inc. announced the PIC12LF1840T48A—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 PIC12LF1840T48A is well suited for use in space-, power- and cost-constrained applications, such as remote keyless entry fobs for automobiles, garage doors and home security systems, as well as a range of other home and building automation systems.
Optimized to run Microchip’s royalty-free KEELOQ advanced code-hopping technology, a security technology used worldwide by leading manufacturers.
Operating voltage of 1.8V
Fully Integrated Transmitter
FSK Operation up to 100 kbps
OOK Operation up to 10 kbps
Operation in 418, 434 and 868 MHz Bands:
8 Selectable center frequencies
+10 dBm or 0 dBm Configurable Output Power:
Up to 100 kbps bit rate in FSK, 10 kbps bit rate in OOK
Price and Availability: The PIC12LF1840T48A is available today for samples, in a 14-pin TSSOP package, and volume production is expected in January. Pricing: $1.06 each in 10,000-unit quantities.
Because the Keeloq(tm) firmware was developped for the 8-bit MCU's,
because the application domain is better served with light programming beit assembly and C,
and most probably because the internal logic interface is already existant in the silicon layout of that family of MCU by Microchip.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
