CAT150089SWI-G

Supervisors Overview

The CAT150089SWI-G is a CMOS serial EEPROM integrated with a system power supervisor, manufactured by onsemi. It features a memory density of 2048 bits organized as 256 words by 8 bits, accessed via an SPI interface. The device operates within a supply voltage range supporting 5V, 3.3V, 3V, and 2.5V systems. It includes brown-out protection where the reset signal activates if the supply voltage falls below the threshold. The component is housed in an 8-pin SOP plastic package and supports data retention for a minimum of 100 years with endurance rated at 1,000,000 write/erase cycles.

Supervisors Feature Summary

• Integrates a CMOS serial EEPROM with a precision voltage supervisor for microcontroller-based systems.
• Provides brown-out protection with active low or high reset output options when supply voltage drops below threshold.
• Utilizes a standard SPI interface for reliable memory access and configuration.

Supervisors Applications

• Microcontroller-based embedded systems requiring non-volatile storage and supervision
• Industrial control units needing power monitoring and data retention
• Consumer electronics utilizing low-voltage operation

Supervisors Procurement Notes

Verify the specific suffix 'G' indicates lead-free and halide-free compliance as per manufacturer standards. Confirm the SOP-8 package outline matches the design footprint requirements. Ensure the SPI interface timing parameters align with the host controller specifications. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when a combined memory and supervisory solution is required to reduce board space. It is suitable for applications needing robust data retention under varying voltage conditions. Consider the SPI compatibility with the target processor. Evaluate the thermal performance within the specified operating temperature range of -40°C to +85°C for the intended environment.

Supervisors Part Context

This part belongs to the CAT15002/04 family of memory and supervisory solutions designed for systems requiring both data storage and power management. It integrates functions typically handled by separate components, simplifying the circuit design. The series is targeted at cost-sensitive and space-constrained applications in industrial and consumer markets.
