If your application streams data faster than that, step up to the BR93H86RF-WCE2 (16Kbit, 1.25 MHz) for more capacity, but the 2 MHz speed on this part keeps bus occupancy low for the 2Kbit footprint. It remains suitable for both new design-ins and ongoing production without a forced migration window. ## Package and supply — 8-SOP, 2.5V to 5.5V Housed in an 8-SOP package (8-SOIC, 4.40 mm width), surface-mount only. The wide supply range covers 3.3V and 5V logic rails without an external regulator. The write cycle time of 4 ms per word or page is consistent across the full voltage and temperature range.","metaTitle":"BR93H56RF-2CE2 Automotive EEPROM, 2Kbit Microwire, 2 MHz","metaDescription":"ROHM BR93H56RF-2CE2 automotive AEC-Q100 EEPROM, 2Kbit, Microwire interface, 2 MHz clock, 2.5V-5.5V supply, -40°C to 125°C, 8-SOP.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.173\\\", 4.40mm Width)","Clock Frequency":"2 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Microwire","Voltage - Supply":"2.5V ~ 5.5V","Memory Organization":"128 x 16","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-SOP","Write Cycle Time - Word, Page":"4ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.49000","currency":"USD"},{"qty":10,"price":"$0.48400","currency":"USD"},{"qty":25,"price":"$0.44920","currency":"USD"},{"qty":50,"price":"$0.44700","currency":"USD"},{"qty":100,"price":"$0.39690","currency":"USD"},{"qty":250,"price":"$0.39188","currency":"USD"},{"qty":500,"price":"$0.38596","currency":"USD"},{"qty":1000,"price":"$0.37565","currency":"USD"},{"qty":2500,"price":"$0.36753","currency":"USD"},{"qty":5000,"price":"$0.33769","currency":"USD"},{"qty":12500,"price":"$0.33176","currency":"USD"},{"qty":25000,"price":"$0.32386","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fe527a5e306815f9a6521a6e14503afa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BR93H56RF-2CE2 compatible with 5V?","answer":"Yes, the supply voltage range is 2.5V to 5.5V, so it works directly on both 3.3V and 5V rails without level shifting."},{"question":"Does BR93H56RF-2CE2 have an automotive grade?","answer":"Yes, it is part of the Automotive, AEC-Q100 series, qualified for automotive applications."},{"question":"Is BR93H56RF-2CE2 SPI or Microwire?","answer":"It uses a Microwire interface (3-wire serial bus with dedicated chip select, clock, and data I/O).
