Detailed Description for BR93A46RFVM-WMTR
Product Overview
The BR93A46RFVM-WMTR from Rohm Semiconductor is a 1Kbit non-volatile EEPROM memory IC with a Microwire serial interface and a 2 MHz clock frequency. It is organized as 64 x 16 bits and operates from a 2.5V to 5.5V supply. The device is specified for surface mounting in an 8-MSOP package with a 2.80mm width, and it is specified with automotive grade and AEC-Q100 qualification. Its write cycle time for word or page operations is 5ms, and the operating temperature range is -40°C to 105°C (TA).
Key Features
- 1Kbit EEPROM memory with 64 x 16 organization for non-volatile data retention.
- Microwire serial interface operating at a 2 MHz clock frequency.
- 5ms write cycle time for word or page operations.
- 2.5V to 5.5V supply voltage range.
- Automotive grade with AEC-Q100 qualification.
- Operating temperature range of -40°C to 105°C (TA).
- Surface mount 8-MSOP package with 2.80mm width.
Applications
- Automotive electronic control units requiring non-volatile storage for configuration or calibration data.
- Embedded controller systems using a Microwire serial interface to retain settings after power removal.
- Low-voltage systems operating from 2.5V to 5.5V that need small non-volatile data storage.
Design & Procurement Notes
Design considerations should include the 2.5V to 5.5V supply range, the 2 MHz Microwire clock limit, and the 5ms word or page write cycle when sequencing memory operations. The 64 x 16 organization defines the available capacity, while the 8-MSOP package and surface mount form factor affect board layout. For applications requiring automotive grade and AEC-Q100 qualification, verify that the system temperature range remains within -40°C to 105°C (TA) and that the supply voltage does not exceed the specified limits.
