Product Summary

AT27C512R-45TU is a low-power, high-performance 524,288-bit one-time programmable read-only memory (OTP EPROM) organized 64K by 8 bits. The AT27C512R-45TU requires only one 5Vpower supply in normal read mode operation. The AT27C512R-45TU is available in a choice of industry-standard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, SOIC, and TSOP packages.With 64K byte storage capability, the AT27C512R-45TU allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.
