AT28HC64B数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The Microchip AT28HC64B is a high-performance64Kbit Parallel EEPROM offering access times to 55ns with power dissipation of220mW. Deselected, CMOS standby current is less than 100μA. Accessed likestatic RAM for the read or write cycle without external components, it containsa 64-byte page register to allow writing of up to 64 bytes simultaneously.Optional Software Data Protection mechanismguards against inadvertent writes; and an extra 64 bytes of EEPROM enablesdevice identification or tracking.
