Microchip Technology Announces PIC® Microcontroller for Passive-Keyless-Entry and Other Wireless Authentication Applications

New PIC® Microcontrollers Combine Data Transmission Security With Power Management

CHANDLER, Ariz., July 25, 2005 [NASDAQ: MCHP - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today 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:

· Precision 8 MHz internal oscillator with software clock switching
· Up to 3.5 Kbytes of Flash program memory
· 128 bytes of RAM
· 256 bytes of EEPROM
· Two analog comparators
· One 8-bit Timer, one 16-bit Timer

nanoWatt low-power and reliability features Include:

· Ultra Low Power Wakeup (ULPW)
· Software-selectable Brownout Reset (BOR)
· Programmable Low Voltage Detect (PLVD)
· Wakeup Reset (WUR) feature
· Enhanced Watchdog Timer (EWDT)

LF analog front end features include:
· Three channels for omni-directional 125 kHz wireless communications
· 3 mV input sensitivity
· Programmable antenna tuning
· Supports batteryless operation
