FEATURES • Precision Supply Voltage Monitor — Dual reset outputs for complex microcontroller systems — Integrated memory write lockout • Guaranteed RESET (RESET#) assertion to VCC=1V • Power-Fail Accuracy Guaranteed • No External Components • 3 and 5 Volt system versions • Low Power CMOS — Active current less than 3mA — Standby current less than 25µA • Memory Internally Organized 512 X 8 — Two Wire Serial Interface (I2C™) – Bidirectional data transfer protocol – Standard 100KHz and Fast 400KHz Precision RESET Controller and 4K I2C Memory With Both RESET and RESET RESET RESET RESET RESET Outputs S24042/S24043 • High Reliability — Endurance: 100,000 erase/write cycles — Data retention: 100 years • 8-Pin SOIC Packages OVERVIEW The S24042 and S24043 are power supervisory devices with 4,096 bits of serial E2PROM. They are fabricated using SUMMIT’s advanced CMOS E2PROM technology and are suitable for both 3 and 5 volt systems. The memory is internally organized as 512 x 8. It features the I2C serial interface and software protocol allowing operation on a simple two-wire bus. The S24042 provides a precision VCC sense circuit and two open drain outputs: one (RESET) drives high and the other (RESET#) drives low whenever VCC falls below VTRIP. The S24043 is identical to the S24042 with the exception being RESET is not bonded out on pin 7.
