The AT27C256R-70RU is a low-power, high-performance 262,144-bit one-time programmable read-only memory (OTP EPROM) organized as 32K by 8 bits. It requires a single 5V power supply for normal read operation, with access times as fast as 45 ns, eliminating the need for speed-reducing WAIT states in high-performance microprocessor systems.
This EPROM utilizes Atmel's scaled CMOS technology for low active power consumption and fast programming. It features a maximum active current of 20 mA at 5 MHz and a maximum standby current of 100 µA. The device supports a voltage range of 4.5V to 5.5V and operates within an industrial and automotive temperature range of -40°C to 85°C.
Available in a JEDEC-standard 28-lead SOIC package, the AT27C256R-70RU is designed for surface mounting. It includes features like two-line control (CE, OE) for flexibility and a rapid programming algorithm that reduces programming time to typically 100 µs/byte. The device also offers 2,000V ESD protection and 200 mA latchup immunity, ensuring high reliability.
This memory component is suitable for storing firmware reliably and accessing it without the delays associated with mass storage media. Its integrated product identification code aids in selecting proper programming algorithms and voltages.
