| HN27512P Series 65536-word x 8-bit One Time Electrically Programmable Read Only Memory The HN27512P is a 65536-word by 8-bit one time electrically programmable ROM. Initially, all bits of the HN27512P are in the "1" state (Output High). Data is introduced by selectively programming "0" into the desired bit locations. This device is packaged in a 28 pin, plastic dual inline package. Therefore, this device can not be rewritten.
