CMOS 2-WIRE SERIAL EEPROM
S-24C01A/02A/04A
The S-24C0XA is a series of 2-wired, low power 1K/2K/4K-bit EEPROMs
with a wide operating range. They are organized as 128-word × 8-bit,
256-word × 8-bit, and 512-word × 8-bit, respectively. Each is capable of
page write, and sequential read.
The time for byte write and page write is the same, i. e., 1 msec. (max.)
during operation at 5 V ± 10%.
„ Features
• Low power consumption
Standby: 1.0 µA Max.
Operating: 0.4 mA Max.
0.3 mA Max.
(V_CC=5.5 V)
(V_CC=5.5 V)
(V_CC=3.3 V)
• Wide operating voltage range
Write: 2.5 to 5.5 V
Read: 1.8 to 5.5 V
• Page write
8 bytes (S-24C01A, S-24C02A)
16 bytes (S-24C04A)
