Description: The Microchip Technology Inc. 93XX46A/B/C devices are 1Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA46C, 93LC46C or 93C46C are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low power, nonvolatile memory applications. The entire 93XX Series is available in standard packages includ ing 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/TDFN and 8-lead TSSOP. All packages are Pb-free (Matte Tin) finish. Features: • Low-Power CMOS Technology • ORG Pin to Select Word Size for ‘46C’ Version • 128 x 8-bit Organization ‘A’ Devices (no ORG) • 64 x 16-bit Organization ‘B’ Devices (no ORG) • Self-Timed Erase/Write Cycles (including Auto-Erase) • Automatic Erase All (ERAL) Before Write All (WRAL) • Power-On/Off Data Protection Circuitry • Industry Standard 3-Wire Serial I/O • Device Status Signal (Ready/Busy) • Sequential Read Function • 1,000,000 Erase/Write Cycles • Data Retention > 200 Years • RoHS Compliant • Temperature Ranges Supported: - Industrial (I) -40°C to +85°C - Automotive (E) -40°C to +125°C
