rfHCS362G/362F

General:

• Combination KEELOQ encoder and synthesized

UHF ASK/FSK transmitter in a single package

• Operates on a single lithium coin cell

- <200 nA typical standby current

- 4.8 to 11.5 mA transmit current

- 2.2 to 5.5V operation

• Integrated solution with minimum external parts

• Separate pin-outs for KEELOQ encoder and RF

transmitter provides for design flexibility

Code Hopping Encoder:

• Programmable minimum code word completion

• Battery low signal transmitted to receiver with pro-

grammable threshold

• Non-volatile EEPROM storage of synchronization

data

• Easy to use EEPROM programming interface

• PWM or Manchester modulation

• Selectable encoder data rate 417 to 3334 bps

• On-chip tunable encoder oscillator

• RF Enable output for transmitter control

• Button inputs have internal pull-down resistors

• Elapsed time and button queuing options

• Current limiting on LED output

• 2-bit CRC for error detection

UHF ASK/FSK Transmitter:

• Conforms to US FCC Part 15.231 regulations and

European ERC 70-03E and EN 300 220-1

requirements

• VCO phase locked to quartz crystal reference;

allows narrow receiver bandwidth to maximize

range and interference immunity

• Crystal frequency divide by 4 output (CLKOUT)

• Transmit frequency range (310 – 440 MHz) set by

Crystal frequency

• ASK Modulation

• FSK Modulation through crystal pulling

(rfHCS362F)

• Adjustable output power: -12 dBm to +2 dBm

• Differential output configurable for single or

double ended loop antenna

• Automatic power amplifier inhibit until PLL lock

Pin Diagrams

Security:

• Programmable 28/32-bit serial number

• Two programmable 64-bit encryption keys

• Programmable 60-bit seed

• Each 69-bit transmission is unique with 32 bits of

hopping code

• Encryption keys are read protected

Applications:

• Automotive Remote Keyless Entry (RKE) systems

• Automotive alarm systems

• Automotive immobilizers

• Community gate and garage door openers

• Identity tokens with usage counters

• Burglar alarm systems

• Building access
