8-Megabit (1M x 8) UV erasable CMOS EPROM

Atmel Corporation 

Rapid Programming Algorithm

A 50 µs CE pulse width is used to program. The address is

set to the first location. VCC is raised to 6.5V and OE/VPP is

raised to 13.0V. Each address is first programmed with one

50 µs CE pulse without verification. Then a verification

reprogramming loop is executed for each address. In the

event a byte fails to pass verification, up to 10 successive

50 µs pulses are applied with a verification after each

pulse. If the byte fails to verify after 10 pulses have been

applied, the part is considered failed. After the byte verifies

properly, the next address is selected until all have been

checked. OE/VPP is then lowered to VIL and VCC to 5.0V. All

bytes are read again and compared with the original data to

determine if the device passes or fails.
