S24042/S24043 are precision reset controllers and 4K I2C memories with both reset and reset outputs
The Summit Microelectronics $24042 and $24043 are power supervisory devices featuring a precision supply voltage monitor and 4,096 bits of serial EEPROM. These devices utilize advanced CMOS E2PROM technology suitable for both 3V and 5V systems.
| Memory Size | 4,096 bits (512 x 8) |
|---|---|
| Operating Voltage | 3V or 5V |
| Interface Standard | I2C (Two Wire Serial) |
| Data Retention | 100 years |
| Package Type | 8-Pin SOIC |
The $24043 is identical to the $24042 with the exception being RESET is not bonded out on pin 7.
The device provides two open drain outputs: one (RESET) drives high and the other (RESET#) drives low whenever Vcc falls below Vtrip.
