1K-16K Microwire Compatible Serial EEPROMs  
Features:  
Description:  
• Densities from 1 Kbits through 16 Kbits  
• Low-power CMOS technology  
Microchip Technology Inc. supports the 3-wire  
Microwire bus with low-voltage serial Electrically  
Erasable PROMs (EEPROM) that range in density  
from 1 Kbits up to 16 Kbits. Each density is available  
with and without the ORG functionality, and selected  
by the part number ordered. Advanced CMOS technol-  
ogy makes these devices ideal for low-power, nonvol-  
atile memory applications. The entire series of  
Microwire devices are available in the standard 8-lead  
PDIP and SOIC packages, as well as the more  
advanced packaging such as the 8-lead MSOP, 8-lead  
TSSOP, 6-lead SOT-23, and 8-lead DFN (2x3). All  
packages are Pb-free.  
• Available with or without ORG function:  
With ORG function:  
- ORG pin at Logic Low: 8-bit word  
- ORG pin at Logic High: 16-bit word  
Without ORG function:  
- ‘A’ version: 8-bit word  
- ‘B’ version: 16-bit word  
• Program Enable pin:  
- Write-protect for entire array  
(93XX76C and 93XX86C only)  
Pin Diagrams (not to scale)  
• Self-timed Erase/Write cycles  
(including auto-erase)

(ex: 93LC46BX)  
• Automatic ERAL before WRAL  
• Power-on/off data protection circuitry  
• Industry standard 3-wire serial I/O  
• Device Status signal (Ready/Busy)  
• Sequential Read function
