Introduction
The AT25128A/256A provides 131,072/262,144 bits of serial electrically-erasable programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The devices are available in space saving 8-lead PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-ball dBGA2 and 8-lead SAP packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions. The AT25128A/256A is enabled through the Chip Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely self-timed, and no separate Erase cycle is required before Write. Block Write protection is enabled by programming the status register with top %, top % or entire array of write protection. Separate Program Enable and Program Disable instructions are provided for additional data protection. Hardware data protection is provided via the WP (overline) pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence.
Features
- Serial Peripheral Interface (SPI) Compatible
- Supports SPI Modes 0 (0,0) and 3 (1,1)
- Data Sheet Describes Mode 0 Operation
- Low-voltage and Standard-voltage Operation – 2.7 (VCC = 2.7V to 5.5V) – 1.8 (VCC = 1.8V to 5.5V)
- 20 MHz Clock Rate (5V)
- 64-byte Page Mode and Byte Write Operation
- Block Write Protection – Protect 1/4, 1/2, or Entire Array
- Write Protect (WP (overline)) Pin and Write Disable Instructions for Both Hardware and Software Data Protection
- Self-timed Write Cycle (5 ms Max)
- High-reliability – Endurance: 1 Million Write Cycles – Data Retention: > ±∞ Years
- 8-lead PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-ball lead Ultra Thin SAP Packages
- Lead-free/Halogen-free
- Available in Automotive
- Die Sales: Wafer Form, Waffle Pack, and Bumped Die
