GENERAL DESCRIPTION

The Pm25LD512/010/020 are 512Kbit/ 1Mbit / 2Mbit Serial Peripheral Interface (SPI) Flash memories, providing

single- or dual-output. The devices are designed to support a 33 MHz clock rate in normal read mode, and 100

MHz in fast read, the fastest in the industry. The devices use a single low voltage power supply, wide operating

voltage 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 Pm25LD512/010/020 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output

(SlO), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. They comply with all

recognized command codes and operations. The dual-output fast read operation provides and effective serial

data rate of 200MHz.

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 4 KByte sectors or uniform 32 KByte

blocks.(Pm25LD020 is uniform 4 KByte sectors or uniform 64 KByte).

The Pm25LD512/010/020 are manufactured on pFLASH™’s advanced non-volatile technology. The devices are

offered in 8-pin SOIC 150mil, 8-contact WSON and 8-pin TSSOP. The devices operate at wide temperatures

between -40°C to +105°C.
