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 4KB sectors grouped either on the top or the bottom

while the remaining sectors are all 256KB

? Configuration 2: Address space consists of thirty-two 4KB 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 region (SSR) of 1024 bytes (32 × 32 bytes)

? HYPERBUS? interface

- JEDEC eXpanded SPI (JESD251) compatible

- DDR option runs up to 400-MBps (200 MHz clock speed)

- Supports data strobe (DS) to simplify the read data capture in high-speed systems

? Legacy (x1) SPI (1S-1S-1S)

- JEDEC eXpanded SPI (JESD251) compatible

- SDR option runs up to 21-MBps (166 MHz clock speed)

? SEMPER? Flash with HYPERBUS? interface devices support default boot in legacy SPI (x1) or HYPERBUS?

interface (x8)

? Functional safety features
