PCI9052的eeprom

我的9052的eeprom选的是93s46,但是用PLXMON的时候写寄存器的按钮总是灰色的，不能使用，最下面显示EEPROM型号未知，请问是否一定要用93cs46,但是我看到echlon的一块卡用的是93S46,工作是正常的，但是我用PLXMON去读寄存器的值时，仍然什么都读不到。希望用过的高手指点，谢谢

不一定要用93S46，对于9050和9052,PLX推荐使用的eeprom为

Fairchild Semiconductor
1K FM93CS46
Note: Must have sequential read function

Holtek Semiconductor
1K HT93LC46
Note: For HT93LC46, ORG pin must be tied to VCC for 16-bit

Integrated Silicon Solution
1K IS93C46-3
Note: No restrictions

Microchip Technology
1K 93AA46
1K 93C46B
1K 93LC46B
Note: Cannot use x8 devices (Cannot use 93Cx6A or 93LCx6A)
Note: For 93AA46, ORG pin must be unconnected or tied to
VCC for 16-bit organization

Rohm Microelectronics
1K BR93LC46

Note: No restrictions

Seiko Instruments
1K S-93C46A
Note: Cannot use "U" devices (Do not support 5V operation)

ST Microelectronics
1K M93C46
1K M93S46

Note: Cannot use "R" devices (Do not support 5V operation)
Note: For M93C46, ORG pin must be unconnected or tied to VCC for 16-bit organization

PLX认为可以替代的器件为:
Atmel Corporation
1K None
Note: Atmel does not have sequential read function

Catalyst Semiconductor
1K None
Note: CAT93C46 does not have the sequential read function

Microchip Technology
1K 93LC46B
Note: Cannot use x8 devices (Cannot use 93LC46A)

别忘了给分！
