MICROCHIP AT93C46DN-SH-T

The AT93C46D provides 1,024 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 64 words of 16 bits each (when the ORG pin is connected to VCC) and 128 words of 8 bits each (when the ORG pin is tied to ground). The device is optimized for use in many industrial and commercial applications where low‑power and low‑voltage operations are essential. The AT93C46D is available in space-saving 8‑lead PDIP, 8‑lead SOIC, 8‑lead TSSOP, 8‑pad UDFN and 8‑ball VFBGA packages. All packages operate from 1.8V to 5.5V. The AT93C46E provides 1,024 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 64 words of 16 bits each only. The AT93C46E does not offer the ORG pin so organization is not user-selectable on this device. The device is optimized for use in many industrial and commercial applications where low‑power and low‑voltage operations are essential. The AT93C46E is also available in space-saving and 8‑lead PDIP, 8‑lead SOIC and 8‑lead TSSOP packages. All packages operate from 1.8V to 5.5V.
