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.
