CSS555 and CSS555C EZ Programmer
The EZ Programmer provides a quick and simple method of reading and programming the CSS555 and CSS555C Micropower Programmable 555 Timer IC from Custom Silicon Solutions. A small Programmable Logic Device controls the serial interface signals used to program and read the ICs. New configuration data is entered via a DIP switch and data is read back after programming and displayed by LEDs. The Program and Read cycles are automatically run each time the power button is pressed and held ON. The LEDs blink while the program cycle is underway and when finished, the new data is displayed on the LEDs until the POWER switch is released.

  • Stand alone programmer
  • No PC required

  • Runs on 2 x AAA batteries
  • Provides both PROGRAM and READ functions
  • Provides access to both Configuration and Capacitor Trim data
  • Comes with a DIP socket, but can be easily be adapted for SOIC packages
