• Lead Free Status / RoHS Status: Compliant

The M25P64 is a 64 Mbit (8 M × 8) Serial Flash produced by ST. Serial SPI Flash is used as
indirect boot memory for the MSC8144 for large-size code (>= 64 kB) segments from the I
Boot EEPROM. The memory is accessed by a high speed SPI-compatible bus. By using the Page
Program instruction, the memory can be programmed from 1 to 256 bytes at a time. The Write
Protect (WP) input allows the user to freeze the size of the area of memory that is protected
against program or erase instructions when low. The WP pin is controlled from the MSC8144
GPIO20. To enable write operation, configure GPIO20 as an output and to drive the high level.
5.9 Reset Operation and Configuration
This section describes overall reset connectivity on the ADS board and how the power-on reset
and hard reset sequences function.
