• Manufacturer Part Number: smj27c256
• Description: 256k Uveprom Semiconductor
• Manufacturer: Austin Semiconductor, Inc.

RECOMMENDED TIMING REQUIREMENTS FOR PROGRAMMING: V
(SNAP! Pulse), T
NOTES:
1. C
The AC testing inputs are driven at 2.4V for logic high and 0.4V for logic low. Timing measurements are
made at 2V for logic high and 0.8V for logic low for both inputs and outputs.
