The BR9080A and BR9016A series are serial EEPROMs that can be connected directly to a serial port and can be
erased and written electrically. Writing and reading is performed in word units, using four types of operation commands.
Communication occurs though CS, SK, DI, and DO pins, WC pin control is used to initiate a write disabled state, enabling
these EEPROMs to be used as one-time ROMs. During writing, operation is checked via the internal status check.
!Applications
Movie, camera, cordless telephones, car stereos, VCRs, TVs, DIP switches, and other battery-powered equipment
requiring low voltage and low current
!Features
1) BR9080AF-W / ARFV-W / ARFVM-W (8k bit) : 512 words ×16 bits
BR9016AF-W / ARFV-W / ARFVM-W (16k bit) : 1024 words × 16bits
2) Single power supply operation
3) Serial data input and output
4) Automatic erase-before-write
5) Low current consumption
Active (5V) : 5mA (max.)
Standby (5V) : 3µA (max.)
6) Noise filter built into SK pin
7) Write protection when VCC is low
Inhibition on inadvertant write with the WC pin.
8) SOP8 / SSOP-B8 / MSOP8
9) High reliability CMOS process
10) 100,000 ERASE / WRITE cycles
11) 10 years Data Retention
