It stores non-volatile parameters — calibration coefficients, device configuration bytes, serial numbers, or fault logs — in equipment that needs to retain data through power cycles. The 1.7 V minimum supply is the spec that matters when this EEPROM shares a 1.8 V MCU rail: it guarantees read and write operation down to the low end of the tolerance band, so a 1.8 V ±5 % rail (1.71 V min) stays within range. The 3 MHz clock rate is the maximum the part guarantees — a host MCU's SPI peripheral running in Microwire mode needs to generate a 3 MHz or slower SCK. At 5 V operation the bus has more noise margin; at 1.8 V the signal edges on a long PCB trace need attention to avoid setup-time violations on the return data. Organized as 512 x 16 bits, the part reads and writes a full 16-bit word per bus transaction. The 5 ms write cycle time per word or page applies after each write command — the host must wait or poll the ready/busy status before the next operation. For a 512-word firmware-parameter table, writing the full array sequentially takes about 2.5 seconds at the worst-case write time.","metaTitle":"ROHM BR93G76F-3BGTE2 8Kbit Microwire EEPROM, 3 MHz, 8-SOP","metaDescription":"ROHM BR93G76F-3BGTE2 8Kbit (512x16) serial EEPROM with 3 MHz Microwire interface, 1.7V-5.5V supply, -40°C to 85°C.

A smaller-density sibling is the BR93G46FVM-3AGTTR (1 Kbit, 64 x 16), which shares the same 3 MHz clock, 1.7 V minimum supply, and 5 ms write cycle, but in a different package. For a larger-density alternative, the BR93H86RF-WCE2 offers 16 Kbit (1 K x 16) with a 1.25 MHz clock and automotive AEC-Q100 qualification."},{"question":"Can BR93G76F-3BGTE2 replace a 93C46 EEPROM?","answer":"Not directly. A 93C46 is a 1 Kbit (64 x 16) device with a similar Microwire interface, but the BR93G76F-3BGTE2 is 8 Kbit (512 x 16) — eight times the density — and operates at up to 3 MHz versus the typical 1 MHz or 2 MHz of older 93C46 parts. The pinout and command set are compatible, but the host firmware must account for the larger address space and faster clock. The 8-SOP package is the same footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/BR93G76F-3BGTE2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/BR93G76F-3BGTE2 when reusing this data.
