概述

Description

FT24C64A-ESR-T is a 64-kbit I2C serial EEPROM (8K x 8) used for nonvolatile storage in microcontroller projects. Key points:
- Interface: I2C two-wire bus; device address 1010xxx with A0–A2 selecting the specific device.
- Memory: 8,192 bytes accessible via a two-byte memory address field (MSB, LSB).
- Operations: Random reads and sequential reads; write operations are page-oriented (typical page size: 32 bytes).
- Performance: Typical write cycle around a few milliseconds (e.g., ~4–5 ms); low-power standby; data retention of many years.
- Voltage and temp: Operates over a wide supply range (commonly 2.7–5.5 V); temperature grades vary by part.
- Packaging: -T usually denotes tape-and-reel packaging; device comes in a standard 8-pin package (SOIC/Mini-DIP variants).
Common uses: microcontroller parameter storage, configuration data, calibration tables, and data logging where nonvolatile memory is needed. For exact electrical specs, timings, and pinout, consult the specific FT24C64A-ESR-T datasheet.

Features

Here are the typical features of FT24C64A-ESR-T (64Kbit I2C serial EEPROM, extended-temp variant):
- Memory: 64 Kbit (8 KBytes) organized as 8K × 8
- Interface: I2C two-wire bus; standard mode up to 100 kHz, fast mode up to 400 kHz
- Addressing: two-byte memory addressing (MSB/LSB) to access full memory
- Page size: 32-byte page write
- Write: random and sequential read; write cycle time ≈ 5 ms (typical)
- Endurance/Retention: ~1,000,000 write cycles; data retention ~100 years
- Hardware addressing: A2–A0 pins for up to 8 devices on one bus
- Write protection: WP pin to lock memory or sectors
- Supply voltage: typically 2.5–5.5 V
- Operating temperature: -40°C to +85°C (industrial/extended temp)
- Package: 8-pin package (ESR variant, RoHS compliant)
Note: please consult the official datasheet for exact electrical specs and any variant-specific nuances.
