Table 3–17. Read Operation Parameters
Existing batches of EPCS1 and EPCS4 manufactured on 0.15 µm process geometry
support AS configuration up to 40 MHz. However, batches of EPCS1 and EPCS4
manufactured on 0.18 µm process geometry support only up to 20 MHz. EPCS16,
EPCS64, and EPCS128 are not affected.
For information about product traceability and transition date to differentiate
between 0.15 µm process geometry and 0.18 µm process geometry EPCS1 and EPCS4,
