1. Description

IS25LQ040B-JNLE/020B/010B/512B/025B (4M/2M/1M/512K/256Kbit) serial flash memory provides a storage solution Simplify the flexibility and performance of the pin count package. ISSI's "Industry Standard Serial Interface" is suitable for the system It has limited space, pins and power. The device is accessed through a 4-wire SPI interface consisting of a serial interface Data input (SI), serial data output (SO), serial clock (SCK) and chip enable (CE#) pins, which are also used as multi-function I/O pins ( See pin description). IS25xQ series flash memory is ideal for code ghosting To RAM, execute in place (XIP) operations and store non-volatile data. The memory array is organized into programmable pages of 256 bytes each. The device supports page programming Among them, 1 to 256 bytes of data can be programmed into the memory by one command. You can erase pages in groups 4 KB sectors, 32 KB blocks, 64 KB blocks and/or entire chip. Uniform sectors and blocks allow larger Provides flexibility for various applications that require reliable data retention. The device supports standard serial peripheral interface (SPI), dual/quad output (SPI), and dual/quad I/O (SPI). The clock frequency of all read modes is up to 104MHz, which can achieve an equivalent clock rate of up to 416MHz (104MHz x 4), which is equivalent to a throughput of 52Mbytes/S. These transfer rates can surpass 16-bit parallel flash memory to allow efficient memory access to XIP (execution in place) operations. The device uses industry-leading non-volatile memory technology and adopts industry-standard lead-free packaging.
