Electronicstalk Product news received on 12 August 2004 from Microchip Technology (contact details) Microcontrollers bring cryptography onboard Two new PIC Flash microcontrollers feature integrated Keeloq cryptographic peripherals, providing a complete solution for remotely controlled security systems and authentication applications. Two new PIC Flash microcontrollers feature integrated Keeloq cryptographic peripherals, providing a complete solution for remotely controlled security systems and authentication applications. Designers of such systems need an integrated solution that provides control of system power consumption and ensures reliable battery-powered operation. The new PIC12F635 and PIC16F636 microcontrollers meet these requirements by providing the Keeloq cryptographic peripheral, nanoWatt Technology power management modes, and reliable battery reset and detect features, including: programmable low voltage detect (PLVD), a wake-up reset (WUR) function, software-controlled brownout reset (BOR) and an extended watchdog timer (EWDT). Applications for the PIC12F635 and PIC16F636 include: remote security control (remote keyless entry, passive keyless entry and remote door locks and gate openers); authentication (property and identity); security systems (remote sensors and their communications); and other general purpose applications. The successful Keeloq technology is based on a proprietary, nonlinear encryption algorithm that creates a unique transmission on every use, rendering code capture and resend schemes useless. The new devices now feature this encryption algorithm as a hardware peripheral integrated within the PIC microcontroller. Key additional features of these two new PIC microcontrollers include: an 8MHz internal oscillator with software clock switching; ultra-low-power wakeup (ULPW); up to 3.5Kbyte of Flash program memory, and up to 256byte of EEPROM data memory; 64 or 128byte of RAM; and analogue comparators. The PIC12F635 and PIC16F636 are supported by Microchip's world-class development tools, including the MPLAB integrated development environment, 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 PICkit 1 Flash starter kit. The two new PIC microcontrollers are available today for general sampling and volume production. The PIC12F635 offers a choice of 8-pin PDIP, SOIC and DFN-S packages, and the PIC16F636 comes in 14-pin PDIP, SOIC and TSSOP outlines. -- ----------------- R. A.
