NM24C16集成電路（IC）的存儲(chǔ)器規(guī)格書(shū)PDF中文資料

General Description

The NM24C16/17 devices are 16,384 bits of CMOS non-volatile electrically erasable memory. These devices conform to all specifications in the Standard IIC 2-wire protocol and are designed to minimize device pin count, and simplify PC board layout requirements.

The upper half (upper 8Kbit) of the memory of the NM24C17 can be write protected by connecting the WP pin to VCC. This section of memory then becomes unalterable unless WP is switched to VSS.
