Product Overview


The AT27C256R-70PU is a 256K (32K x 8bit) one time programmable read only memory (OTP EPROM) device in 28 pin DIP package. This low power, high performance, 262144bit memory requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70ns by eliminating need for speed reducing WAIT states on high performance microprocessor systems. The Atmel scaled CMOS technology provides low active power consumption and fast programming. The AT27C256R-70PU allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. It has additional features to ensure high quality and efficient production use. The rapid programming algorithm reduces time required to program the device and guarantees reliable programming.
  • Fast read access time of 70ns
  • Low power CMOS operation
  • Maximum standby current of 100μA
  • Maximum active current of 20mA at 5MHz
  • High reliability CMOS technology
  • Rapid programming algorithm of 100μs/byte
  • CMOS and TTL compatible inputs and outputs
  • Integrated product identification code
  • Operating temperature range from -40°C to 85°C
