TC57256AD

TOSHIBA MOS MEMORY PRODUCT I DESCRIPTIONI TC57256AD-15 TC57256AD-20 The TC57256AD is a 32,768 word X 8 bit CMOS ultraviolet light erasable and electrically programmable read only memory. For read operation, the TC57256AD's access time is 150ns. The TC57256AD operates from a single 5-volt power supply and has a low power standby mode which reduces power dissipation without increasing access time. The standby mode is achieved by applying a TTL-high level signal to the CE input. Advanced CMOS technology reduces the maximum active current to 40mN6.7MHz and the standby current to lOOJ.LA. For program operation, the programming is achieved by using the high speed prgramming mode. The TC57256AD is fabricated using CMOS technology and N-channel silicon double layer gate MOS technology.
