The write cycle time is the time from a valid stop
condition of a write sequence to the end of the internal
program/erase cycle. During the write cycle, the bus
interface circuits are disabled, SDA is allowed to remain
high, and the device does not respond to its slave
address.
Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.

DESCRIPTION
The CAT24WC01/02/04/08/16 is a 1K/2K/4K/8K/16K bit Serial CMOS E2PROM internally organized as 128/256/512/1024/2048 words of 8 bits each. Catalyst’s advanced CMOS technology substantially reduces device power requirements. The the CAT24WC01/02/04/08/16 feature a 16-byte page write buffer. The device operates via the I2C bus serial interface, has a special write protection feature, and is available in 8-pin DIP, 8-pin SOIC or 8-pin TSSOP.

FEATURES
■ 400 KHZ I2C Bus Compatible*
■ 1.8 to 6.0Volt Operation
■ Low Power CMOS Technology
■ Write Protect Feature
   — Entire Array Protected When WP at VIH
■ Page Write Buffer
■ Self-Timed Write Cycle with Auto-Clear
■ 1,000,000 Program/Erase Cycles
■ 100 Year Data Retention
■ 8-pin DIP, 8-pin SOIC or 8 pin TSSOP
■ Commercial, Industrial and Automotive Temperature Ranges
