NM93C13数据手册集成电路（IC）的存储器规格书PDF

描述 Description

General Description
The NM93C13/C14 is 256/1024, respectively, bits of CMOS electrically erasable memory divided into 16/64 16-bit registers. They are fabricated using National Semiconductor’s floating-gate CMOS process for high speed, high reliability and low power. The NM93C13/C14 is available in an 8-pin SO package to save board space.
The serial interface of the NM93C13/C14 is MICROWIRE™ compatible for simple interface to standard microcontrollers and microprocessors. There are 7 instructions: Read, Erase/Write Enable, Erase, Erase All, Write, Write All, and Erase/Write Disable.
All programming cycles are completely self-timed for simplified operation. The ready/busy status is available on the DO pin to indicate the completion of a programming cycle.
