Microchip Technology Releases Single-Chip KEELOQ Security and Radio Frequency Transmitter Solution.Business Editors/High-Tech Writers Embedded Systems Conference 2002 SAN FRANCISCO--(BUSINESS WIRE)--March 13, 2002 Microchip Technology Inc. (Nasdaq: MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ) Wednesday introduced its new wireless rfHCS362 encoders, which integrate a built-in radio frequency (RF) transmitter with the company's highly secure KEELOQ(R) access control system. Providing both standard, as well as new enhanced KEELOQ features, the rfHCS362G and rfHCS362F are single-package, low-cost authentication devices that require minimal external components for operation. The devices offer designers an easy "no code development required" system solution for secure authentication. The rfHCS362G/362F encoders offer a programmable 32-bit serial number and two 64-bit user-programmable encryption keys for secure identification. The KEELOQ code hopping technology makes each transmission unique, thereby eliminating the threat of capture and re-send schemes while the length of the transmission eliminates the threat of code scanning. Targeted applications include electronic door locks, garage door openers, remote keyless entry (RKE RKE Remote Keyless Entry (car doors) ), burglar alarm systems, property identification, remote control, auto immobilizers and theft protection. The rfHCS362G features an integrated 310-440 MHz Amplitude Shift Key (ASK) transmitter and the rfHCS362F features a Frequency Shift Key (FSK (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. ) transmitter in the same frequency range. Both devices feature adjustable output power (-12dBm to +2dBm) and a voltage controlled oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air (VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. ) phase locked to a quartz crystal reference to allow implementation of a narrow receiver bandwidth to maximize range and interference immunity even at extremely low RF power levels. The device features button queuing (to increase the number of functions and enable a single button to perform multiple functions), Manchester and Pulse Width Modulation See PWM. (PWM) encoding, and timing output bits to determine how long a button was pressed. Programmable time-out options, programmable data rates and code word blanking options, a tunable oscillator and low voltage detector are additional features. Designed for battery operation, the devices feature low standby power consumption (less than 1uA) to improve battery life, low operating voltage of 2.2V, and a direct LED drive that also indicates low battery voltage. The 18-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. rfHCS362G costs $2.14 each and the 20-pin SSOP SSOP Shrink Small Outline Package SSOP Sanitation Standard Operating Procedures (USDA) SSOP Sanitary Standard Operating Procedures SSOP Sharescan-Open Platform (Ecopy) SSOP Site Security Operational Procedures rfHCS362F costs $2.24 each in 1,000-unit quantities. Samples are available now and volume production is scheduled for April. Several application notes on KEELOQ designs are also available on Microchip's Web site. Microchip's KEELOQ Evaluation Kit and the PRO MATE(R) II device programmer support the rfHCS362G/362F devices.
