BR24H64FJ-5ACE2 詳細描述
Product Overview
The BR24H64FJ-5ACE2 from Rohm Semiconductor is a non-volatile EEPROM memory IC that provides 64Kbit of storage in an 8K x 8 organization. It communicates over an I2C interface at a 1 MHz clock frequency and accepts a supply voltage range of 1.7V to 5.5V. The device is offered in an 8-SOP-J surface-mount package, corresponding to an 8-SOIC footprint with 3.90mm width, and supports operation from -40°C to 125°C. A 3.5ms write cycle time is specified for word or page writes, and the part is automotive grade with AEC-Q100 qualification.
Key Features
- 64Kbit EEPROM memory with 8K x 8 organization for byte-oriented non-volatile storage.
- I2C serial interface operating at 1 MHz clock frequency.
- Supply voltage range of 1.7V to 5.5V.
- Write cycle time of 3.5ms for word or page operations.
- Automotive grade with AEC-Q100 qualification.
- Operating temperature range of -40°C to 125°C.
- Surface-mount 8-SOP-J package with 8-SOIC 3.90mm width.
Applications
- Automotive electronic control units that need non-volatile storage for configuration data, fault counters, or calibration parameters.
- Embedded controller boards that retain user settings, serial numbers, or operational thresholds after power loss.
- Sensor and measurement modules that store factory calibration constants or accumulated data between power cycles.
- Power supply and battery management circuits that preserve operating parameters or state information during shutdown.
Design & Procurement Notes
Designers should verify that the host I2C bus and firmware timing are compatible with 1 MHz operation and the 3.5ms word or page write cycle. The 1.7V to 5.5V supply range supports systems whose power rails fall within that window, while the 8-SOP-J surface-mount footprint requires a matching land pattern and solder process. The 8K x 8 organization and 64Kbit capacity should be mapped to the required address and data width. For automotive applications, the AEC-Q100 qualification and -40°C to 125°C operating range support thermal and reliability considerations, though final system-level validation remains necessary.
