Product Overview
The Microchip Technology 25LC1024 is a 1024 Kbit serial EEPROM featuring byte-level and page-level read and write operations over an SPI-compatible serial bus. The device uses three bus signals: Serial Clock (SCK), Serial Data Input (SI), and Serial Data Output (SO), with Chip Select (CS) controlling access. A HOLD pin pauses serial communication without resetting the device, allowing the host controller to service higher-priority interrupts.
The 25LC1024 combines traditional serial EEPROM functionality with Flash-like erase capabilities, supporting page erase (256 bytes), sector erase (32 Kbytes), and chip erase operations without requiring erase cycles before write operations. Sector write protection can be configured to protect none, one-quarter, one-half, or all of the memory array. Built-in power-on/off data protection circuitry and a write-enable latch prevent inadvertent writes.
The device operates from 2.5V to 5.5V and is available in standard 8-lead PDIP (P), SOIJ (SM), and advanced 8-lead DFN (MF) packages. It is manufactured with low-power CMOS technology, drawing a maximum write current of 5 mA and typical read current of 7 mA at 5.5V and 20 MHz. The deep power-down standby current is only 1 µA at 2.5V.
