Write-cycle time is 5 ms per word or page, typical for this density class. ## Supply voltage range — 1.7V to 5.5V The 1.7V minimum supply means this part works with a 1.8V logic rail — common in low-power MCUs and wireless SoCs — without an external boost regulator. The 5.5V top end covers 5V legacy buses. That 3.8 V span is wide enough that the same line item can serve mixed-voltage designs across different product variants, which simplifies procurement qualification. ## 3 MHz Microwire — bus timing and throughput The 3 MHz clock rate on the Microwire interface gives a raw serial bit rate of 3 Mbps. For a 16-bit word, a read cycle takes roughly 5.3 µs plus the 5 ms write time. That write latency is the throughput bottleneck — the 3 MHz speed helps on read-heavy operations like calibration-table fetch or boot-code load, but write-heavy logging will be limited by the 5 ms page-write time. For a procurement review, this part does not introduce obsolescence risk for a new design or a production build.","metaTitle":"ROHM BR93G46FVT-3AGE2 EEPROM, 1Kbit, 3 MHz, 8-TSSOP","metaDescription":"ROHM BR93G46FVT-3AGE2 1Kbit EEPROM, Microwire interface at 3 MHz, 1.7V–5.5V supply, -40°C to 85°C, 8-TSSOP-B.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","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":"3 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Microwire","Voltage - Supply":"1.7V ~ 5.5V","Memory Organization":"64 x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-TSSOP-B","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.64000","currency":"USD"},{"qty":10,"price":"$0.58500","currency":"USD"},{"qty":25,"price":"$0.57760","currency":"USD"},{"qty":50,"price":"$0.57420","currency":"USD"},{"qty":100,"price":"$0.51340","currency":"USD"},{"qty":250,"price":"$0.50900","currency":"USD"},{"qty":500,"price":"$0.50150","currency":"USD"},{"qty":1000,"price":"$0.48355","currency":"USD"},{"qty":3000,"price":"$0.45519","currency":"USD"},{"qty":6000,"price":"$0.44044","currency":"USD"},{"qty":15000,"price":"$0.42597","currency":"USD"},{"qty":30000,"price":"$0.40950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3659bfcc04315b1dd797c924f20cc3bb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BR93G46FVT-3AGE2 compatible with 1.8V systems?","answer":"Yes.

The closest functional peer within ROHM's own portfolio is the BR93G46FVM-3AGTTR, which shares the same 1 Kbit density, Microwire interface, and 3 MHz clock, but comes in an 8-MSOP package instead of 8-TSSOP-B.
