Pm25LQ080中文资料SPI Flash数据手册Chingis规格书

描述 Description

The Pm25LQ080 is 8 Mbit Serial Peripheral Interface (SPI) Flash memories, providing single-, dual or quad-output. The devices are designed to support a 33 MHz fclock rate in normal read mode, and 104 MHz in fast read(Quad output is 100MHz), the fastest in the industry. The devices use a single low voltage power supply, ranging from 2.3 Volt to 3.6 Volt, to perform read, erase and program operations. The devices can be programmed in standard EPROM programmers.
The Pm25LQ080 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output(SI), Serial Data Output(SO), Serial Clock(SCK), and Chip Enable(CE#) pins. The devices support page program mode, where 1 to 256 bytes data can be programmed into the memory in one program operation. These devices are divided into uniform 4KByte sectors or uniform 64 KByte blocks.
The Pm25LQ080 are offered in 8-pin SOlC 208mil,8-pin PDIP,8-pin VVSOP and 8-contact WSON.
