Description:
The Microchip Technology Inc. 25LC512 is a 512 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 25LC512 is available in standard packages includ-
ing 8-lead PDIP, SOIC, and advanced 8-lead DFN
package. All packages are Pb-free and RoHS
compliant.
