Datasheet Serial EEPROM Series Standard EEPROM WLCSP EEPROM BRCA016GWZ-W (16Kbit) General Description 2 BRCA016GWZ-W series is a serial EEPROM of I C BUS Interface Method. Features 2 Completely conforming to the world standard I C BUS. All controls available by 2 ports of serial clock (SCL) and serial data (SDA) Other devices than EEPROM can be connected to the same port, saving microcontroller port. 1.7V to 3.6V Single Power Source Operation most suitable for battery use. Possible FAST MODE 400KHz operation Page Write Mode useful for initial value write at factory shipment. Self-timed Programming Cycle Low Current Consumption At Write Operation (5V) : 0.5mA (Typ) At Read Operation (5V) : 0.2mA (Typ) At Standby Operation (5V) : 0.1A (Typ) Prevention of Write Mistake Write (write protect) function added Prevention of write mistake at low voltage UCSP30L1 Compact Package W(Typ) x D(Typ) x H(Max) :1.30mm x 0.77mm x 0.35mm More than 1 million write cycles More than 40 years data retention Noise Filter Built in SCL / SDA terminal Initial Delivery State FFh BRCA016GWZ-W Capacity Bit Format Type Power Source Voltage Package 16Kbit 2K8 BRCA016GWZ-W 1.7V to 3.6V UCSP30L1 Absolute Maximum Ratings (Ta=25C) Parameter Symbol Limit Unit Remark Supply Voltage V -0.3 to +6.5 V CC Permissible Dissipation Pd 220 mW Derate by 2.2mW/C when operating above Ta=25C Storage Temperature Tstg -65 to +125 C Operating Temperature Topr -40 to +85 C Input Voltage/ - -0.3 to Vcc+1.0 V Output Voltage Memory Cell Characteristics (Ta=25C, Vcc=1.7V to 3.6V) Limit Parameter Unit Min Typ Max (1) Write Cycles 100,000- - Times (1) Data Retention 40 - - Years (1) Not 100% TESTED Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0R2R0G100510-1-2 2013 ROHM Co., Ltd.
