The 900 ns access time is the standard read-cycle timing for this speed grade. ## 5V rail — the key fit constraint Many newer serial EEPROMs in the same package and pinout (e.g., 24LC01BHT-I/MNY) run from 2.5V, making them drop-in compatible with 3.3V logic. The 24C01CT-I/ST stays on a 5V rail only. If your BOM already has a 5V I²C bus, this part fits without translation. If the bus is 3.3V, you need a level shifter or a lower-voltage sibling. ## Active and available It remains a standard catalog item through Microchip's distribution channel, so there is no supply-chain urgency for this line.","metaTitle":"24C01CT-I/ST EEPROM 1Kbit I2C 8-TSSOP, 5V Supply","metaDescription":"Microchip 24C01CT-I/ST serial EEPROM, 1Kbit (128 x 8), I2C 400 kHz, 900 ns access, 4.5V-5.5V supply, -40°C to 85°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"1Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"4.5V ~ 5.5V","Memory Organization":"128 x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-TSSOP","Write Cycle Time - Word, Page":"1ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.41","priceTiers":[{"qty":1,"price":"$0.41000","currency":"USD"},{"qty":25,"price":"$0.39000","currency":"USD"},{"qty":2500,"price":"$0.39000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/255b498957952975edffeda361f5354f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/24C01CT-I%2FST/alternatives.json"},"ai":{"faq":[{"question":"Can 24C01CT-I/ST be used as a drop-in replacement for 24C01?","answer":"The 24C01CT-I/ST is a specific ordering variant (tape-and-reel, industrial temperature, 8-TSSOP) within the broader 24C01 family.
