Two-Wire Serial EEPROM
32K, 64K (8-bit wide)
Low voltage and low power operations:
VCC = 1.8V to 5.5V
Maximum Standby current < 1µA (typically 0.02µA and 0.06µA @ 1.8V and 5.5V respectively).
32 bytes page write mode.
Partial page write operation allowed.
Internally organized: 4096 × 8 (32K), 8192 × 8 (64K).
Standard 2-wire bi-directional serial interface.
Schmitt trigger, filtered inputs for noise protection.
Self-timed Write Cycle (5ms maximum).
1 MHz (5V), 400 kHz (1.8V, 2.5V, 2.7V) Compatibility.
Automatic erase before write operation.
Write protect pin for hardware data protection.
High reliability: typically 1, 000,000 cycles endurance.
100 years data retention.
Industrial temperature range (-40o C to 85o C).
Standard 8-pin DIP/SOP/TSSOP/MSOP/DFN and 5-pin SOT23 Pb-free packages.
The FT24C32A/64A series are 32768/65536 bits of serial Electrical Erasable and Programmable Read Only Memory,
commonly known as EEPROM. They are organized as 4096/8192 words of 8 bits (one byte) each. The devices are
fabricated with proprietary advanced CMOS process for low power and low voltage applications. These devices are
available in standard 8-lead DIP, 8-lead SOP, 8-lead TSSOP, 8-lead MSOP, 8-lead DFN, and 5-lead SOT23 packages.
A standard 2-wire serial interface is used to address all read and write functions. Our extended VCC range (1.8V to
5.5V) devices enables wide spectrum of applications.
