• Manufacturer Part Number: smj27c512
• Description: 512k Uveprom Uv Erasable Programmable Read-only Memory
• Manufacturer: Austin Semiconductor, Inc.

CAPACITANCE OVER RECOMMENDED RANGES OF SUPPLY VOLTAGE AND
OPERATING CASE TEMPERATURE, f = 1MHz*
* Capacitance measurements are made on sample basis only.
** All typical values are at T
SWITCHING CHARACTERISTICS OVER RECOMMENDED RANGES OF SUPPLY
VOLTAGE AND OPERATING CASE TEMPERATURE
NOTES:
1. Timing measurements are made at 2V for logic high and 0.8V for logic low. (see Figure 2)
2. Common test conditions apply for t
3. Value calculated from 0.5V delta to measured output level. This parameter is only sampled and not 100% tested.
RECOMMENDED TIMING REQUIREMENTS FOR PROGRAMMING: V
