LS7220 Description

Short technical summary and product information.

The LS7220 from LSI Computer Systems Inc. is a versatile digital lock integrated circuit primarily designed for automotive ignition anti-theft applications. This MOS circuit can recognize one four-digit combination out of a possible 5040 combinations when interfaced with a ten-digit keypad.

 

Key features include a SENSE input to enable operation, a Save Memory function for valet parking, and a Convenience Delay controlled by an external capacitor. It provides static or momentary lock control output, along with Save Memory and Lock Status outputs that can directly drive LED indicators.

 

The LS7220 operates within a voltage range of +5V to +18V. It is available in DIP and SOIC package types, making it suitable for various automotive integration needs. The hard-wire programmed combinations offer a secure and reliable locking mechanism.

 

This IC is configured with features essential for automotive ignition security, including the ability to maintain an unlock condition during short interruptions of the SENSE input, ensuring uninterrupted operation. The Save Memory feature allows for temporary disabling of the lock for services like valet parking.
