Description:
The Microchip Technology Inc. 25LC1024 is a 1024
Kbit serial EEPROM memory with byte-level and page-
level serial EEPROM functions. It also features Page,
Sector and Chip erase functions typically associated
with Flash-based products. These functions are not
required for byte or page write operations. The memory
is accessed via a simple Serial Peripheral Interface
(SPI) compatible serial bus. The bus signals required
are a clock input (SCK) plus separate data in (SI) and
data out (SO) lines. Access to the device is controlled
by a Chip Select (CS) input.
Communication to the device can be paused via the
hold pin (HOLD). While the device is paused, transi-
tions on its inputs will be ignored, with the exception of
Chip Select, allowing the host to service higher priority
interrupts.
The 25LC1024 is available in standard packages
including 8-lead PDIP and SOIJ, and advanced 8-lead
DFN package. All devices are Pb-free.

... CS goes low. If the clock line is shared with other peripheral devices on the SPI bus, the user can assert the HOLD input and place the 25LC1024 in ‘HOLD’ mode. After releasing the HOLD pin, operation will resume from the point when the HOLD was asserted. ...

... Read Sequence The device is selected by pulling CS low. The 8-bit READ instruction is transmitted to the 25LC1024 followed by the 24-bit address, with seven MSBs of the address being “don’t care” bits. After the correct READ instruction and address are sent, the data stored in the memory at the selected address is shifted out on the SO pin ...

... Write Sequence Prior to any attempt to write data to the 25LC1024, the write enable latch must be set by issuing the WREN instruction (Figure 2-4). This is done by setting CS low and then clocking out the proper instruction into the 25LC1024. After all eight bits of the instruction are transmitted, the CS must be brought high to set the write enable latch ...

... Write Enable (WREN) and Write Disable (WRDI) The 25LC1024 contains a write enable latch. See Table 2-4 for the Write-Protect Functionality Matrix. This latch must be set before any write operation will be completed internally. The WREN instruction will set the latch, and the WRDI will reset the latch. ...

... Write Status Register Instruction (WRSR) The Write Status Register instruction (WRSR) allows the user to write to the nonvolatile bits in the STATUS register as shown in Table 2-2. The user is able to select one of four levels of protection for the array by writing to the appropriate bits in the STATUS register. ...

... DEEP POWER-DOWN MODE Deep Power-Down mode of the 25LC1024 is its lowest power consumption state. The device will not respond to any of the Read or Write commands while in Deep Power-Down mode, and therefore it can be used as an additional software write protection feature. The Deep Power-Down mode is entered by driving CS low, followed by the instruction code (Figure 2-11) onto the SI line, followed by driving CS high ...
