CMOS SERIAL E2PROM
S-93C46B/56B/66B
The S-93C46B/56B/66B is a high speed, low current
consumption, 1/2/4 K-bit serial E2PROM with a wide
operating voltage range. It is organized as 64-word
× 16-bit, 128-word × 16-bit, 256-word × 16-bit,
respectively. Each 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: 1.5 µA Max. (VCC = 5.5 V)
Operating: 0.8 mA Max. (VCC = 5.5 V)
0.4 mA Max. (VCC = 2.5 V)
• Wide operating voltage range Read:
1.8 to 5.5 V (at −40 to +85°C)
Write:
2.7 to 5.5 V (at −40 to +85°C)
• Sequential read capable
• Write disable function when power supply voltage is low
• Function to protect against write due to erroneous instruction recognition
• Endurance:
107 cycles/word* (at +25°C) write capable,
106 cycles/word* (at +85°C)
3 × 105 cycles/word* (at +105°C)
* For each address (Word: 16 bits)
• Data retention: 10 years (after rewriting 106 cycles/word at +85°C)
• S-93C46B:
1 K-bit NM93CS46 instruction code compatible
• S-93C56B:
2 K-bit NM93CS56 instruction code compatible
• S-93C66B:
4 K-bit NM93CS66 instruction code compatible
• High-temperature operation: +105°C Max. supported
(Only S-93Cx6BD0H-J8T2, S-93Cx6BD0H-T8T2)
