特性 Features

• Infineon® 45-nm MIRRORBIT™ technology that stores two data bits in each memory array cell

• Sector architecture options

- Uniform: Address space consists of all 256KB sectors

- Hybrid:

• Configuration 1 - Address space consists of thirty-two 4 KB sectors grouped either on the top or the bottom

while the remaining sectors are all 256KB

• Configuration 2 - Address space consists of thirty-two 4 KB sectors equally split between top and bottom

while the remaining sectors are all 256KB

• Page programming buffer of 256 or 512 bytes

• OTP secure silicon array of 1024 bytes (32  32 bytes)

• Octal interface (8S-8S-8S, 8D-8D-8D)
