The White 68 lead G2T/G1U CQFP fills the same fit and function as the JEDEC 68 lead CQFJ or 68 PLCC. But the G2T/ G1U has the TCE and lead inspection advantage of the CQFP form.

NOTES:
VZ is programmable from -2V to +7V. IOL & IOH programmable from 0 to 16mA. Tester Impedance Z0 = 75 Ω.
VZ is typically the midpoint of VOH and VOL.
IOL & IOH are adjusted to simulate a typical resistive load circuit. ATE tester includes jig capacitance.

WRITE
A write cycle is initiated when OE is high and a low pulse is on WE or CS with CS or WE low. The address is latched on the falling edge of CS or WE whichever occurs last. The data is latched by the rising edge of CS or WE, whichever occurs first. A byte write operation will automatically continue to completion.
WRITE CYCLE TIMING
Figures 5 and 6 show the write cycle timing relationships. A write cycle begins with address application, write enable and chip select. Chip select is accomplished by placing the CS line low. Write enable consists of setting the WE line low. The write cycle begins when the last of either CS or WE goes low.
The WE line transition from high to low also initiates an internal 150 sec delay timer to permit page mode operation. Each subsequent WE transition from high to low that occurs before the completion of the 150 sec time out will restart the timer from zero. The operation of the timer is the same as a retriggerable one-shot.
