MX25L1605A
16M-BIT [x 1] CMOS SERIAL FLASH
The MX25L1605A product will be phase-out, and is not recommended for new
design. The MX25L1605A will be migrated to MX25L1605D, which is a functional
compatible product. Please refer to MX25L1605D datasheet for new design.

block); 14s(typ.) and 30s(max.)/chip(16Mb)
• Low Power Consumption
- Low active read current: 12mA(max.) at 85MHz, 8mA(max.) at 66MHz and 4mA(max.) at 33MHz
- Low active programming current: 15mA (max.)
- Low active erase current: 15mA (max.)

• Minimum 100,000 erase/program cycles
SOFTWARE FEATURES
• Input Data Format
- 1-byte Command code
• Block Lock protection
- The BP0~BP2 status bit defines the size of the area to be software protected against Program and Erase instructions.
• Auto Erase and Auto Program Algorithm
-
Automatically erases and verifies data at selected sector
-
Automatically programs and verifies data at selected page by an internal algorithm that automatically times the
program pulse widths (Any page to be programed should have page in the erased state first)

GENERAL DESCRIPTION
The MX25L1605A is a CMOS 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. The
MX25L1605A features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The
three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device
is enabled by CS# input.
The MX25L1605A provides sequential read operation on whole chip.
After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify the specified
page or sector/block locations will be executed. Program command is executed on page (256 bytes) basis, and erase
command is executes on chip or sector(4K-bytes) or block(64K-bytes).
To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read
command can be issued to detect completion status of a program or erase operation via WIP bit.
When the device is not in operation and CS# is high, it is put in standby mode and draws less than 20uA DC current.
The MX25L1605A utilizes MXIC's proprietary memory cell, which reliably stores memory contents even after 100,000
program and erase cycles.
