General Description
The A27020A chip is a high-performance 2,097,152 bit
one-time programmable read only memory (OTP
EPROM) organized as 256K by 8 bits. The A27020A
requires only 5V power supply in normal read mode
operation and any input signals are TTL levels. The
A27020A is available in industry standard 32 pin dual-
in-line and 32 pin PLCC packages.
