The CAT15002 (see table below) is a memory and supervisory solution for microcontroller based systems. A CMOS serial EEPROM memory and a system power supervisor with brown-out protection are integrated together. Memory interface is via SPI bus serial interface. The CAT15002 provides a precision VCC sense circuit with two reset output options: CMOS active low output or CMOS active high. The RESET output is active whenever VCC is below the reset threshold or falls below the reset threshold voltage. The power supply monitor and reset circuit protect system controllers during power up/down and against brownout conditions. Seven reset threshold voltages support 5V 3.3V 3V and 2.5V systems. If power supply voltages are out of tolerance reset signals become active preventing the system microcontroller ASIC or peripherals from operating. Reset signals become inactive typically 240ms after the supply voltage exceeds the reset threshold level. Memory Size Selector ProductMemory Density CAT150022-Kbit CAT150044-Kbit
