PT28C020-90 Description

Short technical summary and product information.

The PT28C020-90 is a 2M Bit One-Time Programmable (OTP) Memory IC manufactured by Princeton Technology Corp. Utilizing advanced CMOS technology, this component offers efficient operation with low power consumption. It is organized as 256K x 8 bits, providing a substantial memory capacity for various applications.

The key electrical characteristic is its read access time of 90 nanoseconds, ensuring quick data retrieval. The device operates with a typical active current of 30mA and a very low standby current of 20µA. Programming can be performed either on-board or via a programmer, requiring a programming voltage of 12.75V and a typical programming pulse duration of 10µs.

Designed for microprocessor compatibility, the PT28C020-90 features fast turn-off times. Its pin configuration and programming algorithm are compatible with industry-standard 27020 and 27C020 EPROMs. The memory IC is available in two standard 32-pin package types: PDIP (600 mil) and PLCC, supporting both through-hole and surface-mount assembly methods respectively.

This OTP memory is suitable for applications requiring non-volatile data storage where the data is programmed once. Its compatibility with established EPROM standards makes it a viable option for legacy system upgrades or new designs needing reliable, cost-effective memory solutions.
