Description
FT24C64A-ESR-T is a 64-kbit I2C serial EEPROM. It provides non-volatile storage (8 kB) for embedded systems, accessible over a 2-wire I2C bus.
Key points:
- Capacity and organization: 8,192 bytes, 8 bits per location.
- Interface: I2C (2-wire), standard to fast mode up to 400 kHz.
- Addressing: 7-bit device address = 1010 A2 A1 A0; A2–A0 pins set the lower bits (default 0,0,0 → 0x50). Memory addressed with two bytes (MSB, LSB) for 0x0000–0x1FFF.
- Page write: up to 32 bytes per write; typical write cycle ~5 ms.
- Random and sequential read support.
- Protection: WP pin for write protection; A0–A2 allow multiple devices on the same bus.
- Power and temp: Vcc 1.8–5.5 V; operating temp around -40°C to 85°C (industrial variant).
- Package: 8-pin (Vcc, GND, SDA, SCL, WP, A2, A1, A0); “-T” often denotes Tape & Reel packaging.
Applications: config/data storage, logging, firmware offload. Always consult the exact datasheet for voltages, timing, and packaging.
