BU9829GUL-W
●Description
BU9829GUL-W is Serial EEPROM built-in LDO regulator by SPI BUS interface.
●Features
○EEPROM PART
1) 2,048 words×8 bits architecture serial EEPROM
2) Wide operating voltage range (1.6V～3.6V)
3) Serial Peripheral Interface
4) Self-timed write cycle with automatic erase
5) Low Power consumption
Write
(3.6V) : 1.5mA (Typ.)
Read (3.6V) : 0.5mA (Typ.)
Standby (3.6V) : 0.1µA (Typ.)
6) Auto-increment of registers address for Read mode
7) 32 byte Page Write mode
8) DATA security
Defaults to power up with write-disabled state
Software instructions for write-enable/disable
Block writes protection by status register
Write inhibit at low Vcc
9) Initial data FFh in all address, 00h in status register and 10 in VSET[1:0].
10) Data retention: 10 years
11) Endurance : 100,000 erase/write cycles
○LDO REGULATOR PART
12) Low power consumption
Standby (3.6V) : 0.1 µA (Typ.)
Operation (3.6V) : 0.1mA (Typ.)
13) Power on/off by enable pin
14) Initial LDO output voltage 2.9V
15) Setting output voltage by EEPROM command (VSET WRITE)
