Description

The Atmel® AT25640B-MAHL-T provides 32768-/65536-bits of serial electrically-erasable programmable read-only memory (EEPROM) organized as 4096/8192 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 AT25640B-MAHL-T is available in space-saving 8-lead JEDEC SOIC, 8-lead UDFN, 8-lead XDFN, 8-lead TSSOP, and 8-ball VFBGA packages. The AT25640B-MAHL-T is enabled through the Chip Select pin (CS) and accessed via a three-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. AT25640B-MAHL-T Features • Serial Peripheral Interface (SPI) Compatible• Supports SPI Modes 0 (0,0) and 3 (1,1)– Datasheet Describes Mode 0 Operation• Low-voltage and Standard-voltage Operation– 1.8 (VCC = 1.8V to 5.5V)• 20MHz Clock Rate (5V)• 32-byte Page Mode• Block Write Protection– Protect 1/4, 1/2, or Entire Array• Write Protect (WP) Pin and Write Disable Instructions for Both Hardware and Software Data Protection• Self-timed Write Cycle (5ms max)• High Reliability– Endurance: One Million Write Cycles– Data Retention: 100 Years• Green (Pb/Halide-free/RoHS Compliant) Packaging Options• Die Sales: Wafer Form, Tape and Reel, and Bumped Wafers
