The Microchip Technology AT27C020-90PC is a high-performance, low-power 2,097,152-bit One-Time Programmable Read-Only Memory (OTP EPROM) organized as 256K by 8 bits. It requires a single 5V power supply for normal read operations, with access times as fast as 55 ns, eliminating the need for wait states in high-performance microprocessor systems.
This device offers a 90 ns access time and operates within a voltage range of 4.5V to 5.5V. It consumes a maximum of 25 mA during active operation at 5 MHz and a low 100 µA in standby mode. The AT27C020 is available in industry-standard JEDEC-approved packages, including the 32-lead PDIP, PLCC, and TSOP. The specific variant, AT27C020-90PC, comes in a 32-PDIP package suitable for through-hole mounting.
Key features include CMOS and TTL-compatible inputs and outputs, 2,000V ESD protection, and 200 mA latch-up immunity. The Rapid Programming Algorithm allows for typical programming times of 100 µs/Byte. The integrated product identification code aids in programming equipment selection. This EPROM is designed for applications requiring reliable firmware storage and fast access without the delays of mass storage media.
