GENERAL DESCRIPTION
The IS25CD512/010 and IS25LD020 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 to
perform read, erase and program operations. The devices can be programmed in standard EPROM programmers.
The IS25CD512/010 and IS25LD020 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.(IS25LD020 is uniform 4
KByte sectors or uniform 64 KByte).
The IS25CD512/010 and IS25LD020 are manufactured on pFLASH™’s advanced non-volatile technology. The devices are
offered in a variety of packages for all critical needs. The devices operate at wide temperatures between -40°C to +105°C.

SYSTEM CONFIGURATION
IS25CD512/010 & IS25LD020
The IS25CD512/010 and IS25LD020 devices are designed to interface directly with the synchronous Serial Peripheral
Interface (SPI) of the Motorola MC68HCxx series of microcontrollers or any SPI interface-equipped system controllers. The
devices have two superset features that can be enabled through specific software instructions and the Configuration

DEVICE OPERATION (CONTINUED)
IS25CD512/010 & IS25LD020
JEDEC ID READ COMMAND (READ PRODUCT IDENTIFICATION BY JEDEC ID)
OPERATION
The JEDEC ID READ instruction allows the user to read the followed by the first Manufacturer ID (9Dh) and the Device ID
manufacturer and product ID of devices. Refer to Table 11 (22h, in the case of the IS25LD020), each bit shifted out
Product Identification for pFlash Manufacturer ID and Device during the falling edge of SCK. If CE# stays low after the last
ID. After the JEDEC ID READ command is input, the second bit of the Device ID is shifted out, the Manufacturer ID and
Manufacturer ID (7Fh) is shifted out on SO with the MSB first, Device ID will loop until CE# is pulled high.
