Microchip's PIC Targets Passive-Keyless-Entry Wireless Authentication

7/25/2005 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced a Flash, 8-bit PIC® microcontroller with a 3-channel, transponder analog front end and an integrated KEELOQ® cryptographic peripheral. The combination of this new transponder analog front end, KEELOQ peripheral and low power consumption via nanoWatt Technology provides a total solution for passive-keyless-entry (PKE) and other wireless authentication applications.

Designers of wireless security systems and authentication products require an integrated solution for communication, security, and reliable low-power operation. The new PIC16F639 microcontroller meets these needs by providing engineers with the three-channel low-frequency (LF) transponder analog front end, the KEELOQ cryptographic peripheral, nanoWatt Technology, and the power of a PIC microcontroller -- all in a small 20-pin SSOP package.

"Microchip is building on its technology leadership in microcontrollers, analog and secure-data ICs by combining our PIC microcontroller core with an analog front end and the proven KEELOQ security technology," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Development Division. "This new microcontroller provides a complete solution for PKE and authentication systems."

Applications for the PIC16F639 include: Automotive (PKE, tire-pressure monitoring systems); Authentication (intelligent RFID, property and identity, hospital systems, computer access); Security Systems (door locks, gate openers, doggie doors, remote sensors and their intercommunication); and other General Purpose applications.

The three-channel transponder analog front end provides bi-directional LF communication, commonly used in PKE and RFID applications. KEELOQ technology is based on a proprietary, non-linear encryption algorithm that creates a unique transmission on every use, rendering code capture and resend schemes useless. Additional key features of the PIC16F639 microcontroller include:

nanoWatt low-power and reliability features Include:

LF analog front end features include:

Tools, Availability and Pricing
The PIC16F639 is supported by Microchip's world-class development tools, including: the MPLAB® Integrated Development Environment (IDE), MPLAB ICE 2000 in-circuit emulator, MPLAB PM3 universal device programmer, PICSTART® Plus low-cost development system, MPLAB ICD 2 in-circuit debugger/programmer and the new PICkit™ 2 Starter Kit (expected to be available in August). In addition, a complete PIC16F639-based Passive Keyless Entry Reference Design (part # APGRD001) is expected to be available in calendar Q3 2005.

The new PIC microcontroller is available today for sampling in a 20-pin SSOP package, and volume production is expected in calendar Q3 2005. In 10,000-unit quantities, the PIC16F639 is $2.18 each.
