Low-Voltage OTP
EPROM
Description
The AT27LV1026 is a high performance 16-bit interleaved low-voltage 1,048,576-bit
one-time programmable read only memory (OTP EPROM) organized as 2 x 32K x 16
bits. It requires only one supply in the range of 3.0V to 3.6V in normal read mode
operation.

1. VCC must be applied simultaneously with or before VPP, and removed simultaneously with or after VPP.
2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and IPP.
