Description
The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial
electrically-erasable programmable read-only memory (EEPROM) organized as
1024/2048/4096/8192 words of 8 bits each. The device is optimized for use in many
automotive applications where low-power and low-voltage operation are essential.
The AT25080A/160A/320A/640A is available in space-saving 8-lead PDIP, 8-lead
JEDEC SOIC and 8-lead TSSOP packages.
The AT25080A/160A/320A/640A is enabled through the Chip Select pin (CS) and
accessed via a three-wire interface consisting of Serial Data Input (SI), Serial Data
Output (SO), and Serial Clock (SCK). All programming cycles are completely selftimed,
and no separate erase cycle is required before write.
Block write protection is enabled by programming the status register with one of four
blocks of write protection. Separate program enable and program disable instructions
are provided for additional data protection. Hardware data protection is provided via
the WP pin to protect against inadvertent write attempts to the status register. The
HOLD pin may be used to suspend any serial communication without resetting the
serial sequence.

描述
的at25080a / 160a / 320a / 640a提供8192 / 16384 / 32768 / 65536位的串行
电可擦除可编程只读存储器(EEPROM)
1024 / 2048 / 4096 / 8192字每个8位。该设备被优化用于许多
在低功耗和低电压操作的汽车应用是必不可少的。
的at25080a / 160a / 320a / 640a在节省空间的8引脚PDIP,8引脚
JEDEC的SOIC封装和8引脚TSSOP封装。
的at25080a / 160a / 320a / 640a是启用通过芯片选择引脚(CS)和
访问通过一三线接口组成的串行数据输入(SI),串行数据
输出(SO),和串行时钟(SCK)。所有的编程周期完全自定时,
在写入之前没有单独的擦除周期。
块写保护启用了编程状态寄存器的四个之一
写保护块。独立程序启用和程序禁用指令
提供额外的数据保护。硬件数据保护是通过
可湿性粉剂引脚,以防止无意中写尝试状态寄存器。这个
保持引脚可用于暂停任何串行通信,而无需重置
串行序列。
