CMOS SERIAL E2PROM
S-93A46A/56A/66A
The S-93A46A/56A/66A is a high-temperature
operation, high speed, low current consumption, 1 K-
bit, 2 K-bit and 4 K-bit serial E2PROM with a wide
operating voltage range. It is organized as 64-word ×
16-bit, 128-word × 16-bit and 256-word × 16-bit in
each. It is capable of sequential read, at which time
addresses are automatically incremented in 16-bit
blocks. The instruction code is compatible with the
NM93CS46/56/66.
Features
• Low current consumption
Standby: 3.0 µA Max. (VCC = 5.5 V)
Operating: 1.0 mA Max. (VCC = 5.5 V)
0.6 mA Max. (VCC = 2.7 V)
• Wide operating voltage range Read: 2.7 to 5.5 V
Write: 2.7 to 5.5 V
• Sequential read capable
• Write disable function when power supply voltage is low
• Function to protect against write due to erroneous instruction recognition
• CMOS schmitt input (CS, SK)
• Endurance:
106 cycles/word* (at +85°C)
1.5 × 105 cycles/word* (at +125°C)
* For each address (Word: 16 bits)
• Data retention:
15 years (after rewriting 1.5 × 105 cycles/word at +125°C)
• High-temperature operation: +125°C Max.
• Lead-free products
