CAT1027
Description
The CAT1026 and CAT1027 are plete memory and supervisory
.onsemi. solutions for microcontroller- based systems. A EEPROM Serial 2k- bit I2C memory and a system power supervisor with brown- out protection are integrated together in low power CMOS technology. Memory interface is via a 400 k Hz I2C bus.
The CAT1026 and CAT1027 provide a precision VCC sense circuit with five reset threshold voltage options that support 5 V, 3.3 V and 3 V systems. The power supply monitor and reset circuit protects
SOIC- 8 CASE 751BD
TSSOP- 8 CASE 948S memory and systems controllers during power up/down and against brownout conditions. If power supply voltages are out of tolerance reset signals bee active preventing the system microcontroller,
ASIC, or peripherals from operating.
The CAT1026 features two open drain reset outputs: one (RESET) drives high and the other (RESET) drives low whenever VCC falls
MSOP- 8 CASE 846AD
TDFN- 8 CASE 511AL below the threshold. Reset outputs bee...
