The CAT1024 and CAT1025 are complete memory and supervisory solutions for microcontroller−based systems. A 2k−bit serial EEPROM memory and a system power supervisor with brown−out protection are integrated together in low power CMOS technology. Memory interface is via a 400 kHz I2C bus. The CAT1025 provides a precision VCC sense circuit and two open drain ou.
a 16−byte page. In addition, hardware data protection is provided by a VCC sense circuit that prevents writes to memory whenever VCC falls below the reset threshold or until VCC reaches the reset threshold during power up.
Available packages include a surface mount 8−pin SOIC, 8−pin TSSOP, 8−pin TDFN and 8−pin MSOP packages. The TDFN package thickness is 0.8 mm maximum. TDFN footprint is 3 x 3 mm.
