Description

25L1005MC is a CMOS 1,048,576 bit serial Flash memory, which is configured as 131,072 x 8 internally. The MX25L1005 feature 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 MX25L1005 provide 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)

Features:

• Serial Peripheral Interface (SPI) compatible — Mode 0 and Mode 3

• 1,048,576 x 1 bit structure

• 32 Equal Sectors with 4K byte each
– Any Sector can be erased individually

• 2 Equal Blocks with 64K byte each
– Any Block can be erased individually

• Single Power Supply Operation
– 2.7 to 3.6 volt for read, erase, and program operations

• Latch-up protected to 100mA from -1V to Vcc +1V

Pinouts:

1. CS# Chip Select

2. SI Serial Data Input

3. SO Serial Data Output

4. SCLK Clock Input

5. HOLD# Hold, to pause the device without deselecting the device

6. VCC + 3.3V Power Supply

7. GND Ground

The MX25L1005 is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transition. During power up the device automatically resets the state machine in the standby mode.

Description

25Q32 is 32M-bit Serial Flash Memory.

1. Memory Organization: The memory is organized in a serial manner, which means data is accessed and written one bit at a time in a sequential order. Serial flash memories are commonly used when space and pin count are limited, and when data transfer rates are not critical.

2. Flash Memory Technology: Flash memory is a type of non-volatile memory that retains data even when power is removed. It is commonly used in various electronic devices for storing firmware, configuration data, and other types of data that need to be retained when the power is off.

The W25Q80 (8M-bit), W25Q16 (16M-bit), and W25Q32 (32M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and 1µA for power-down. All devices are offered in space-saving packages.

Flexible Architecture with 4KB sectors :

1. Uniform Sector Erase (4K-bytes)

2. Block Erase (32K and 64K-bytes)

3. Program one to 256 bytes

4. Up to 100,000 erase/write cycles

5. 20-year data retention

The SPI Chip Select (/CS) pin enables and disables device operation. When /CS is high the device is
deselected and the Serial Data Output (DO, or IO0, IO1, IO2, IO3) pins are at high impedance. When
deselected, the devices power consumption will be at standby levels unless an internal erase, program
or status register cycle is in progress.
