描述 Description

The ACEH25D200G is 2M-bit Serial Peripheral Interface (SPI) Flash memory, and supports the Dual SPI:

Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO). The Dual Output data is transferred with speed of

108Mbits/s. The device uses a single low voltage power supply, ranging from 2.7 Volt to 3.6 Volt.

Additionally, the device supports JEDEC standard manufacturer and device ID.

In order to meet environmental requirements, offers an 8-pad USON 3x2-mm packages.
