CAT93C56 CATALYST [Catalyst Semiconductor], CAT93C56 Datasheet - Page 3

• Manufacturer Part Number: CAT93C56
• Description: 2K-Bit Microwire Serial EEPROM
• Manufacturer: CATALYST [Catalyst Semiconductor]

Note:
(1) Address bit A8 for 256x8 ORG and A7 for 128x16 ORG are "Don't Care" bits, but must be kept at either a "1" or "0" for READ, WRITE
(2) This parameter is tested initially and after a design or process change that affects the parameter.
