The CAT24FC16 is a 16kb Serial CMOS EEPROM internally organized as 2048 words of 8 bits each. Catalyst’s advanced CMOS technology substantially reduces device power requirements. The CAT24FC16 features a 16-byte page write buffer. The device operates via the I2C bus serial interface and is available in 8-pin DIP, 8-pin SOIC, 8-pin TSSOP, 8-pin MSOP and TDFN packages.

The CAT1026 and CAT1027 are complete memory and supervisory solutions for microcontroller-based systems. A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS techno– logy. Memory interface is via a 400kHz I2C bus. The CAT1026 and CAT1027 provide a precision VCC sense circuit with five reset threshold voltage options that support 5V, 3.3V and 3V systems. The power supply monitor and reset circuit protects memory and systems controllers during power up/down and against brownout conditions. If power supply voltages are out of normal range, a reset is triggered to protect the system. Reset voltage may be configured externally via an external pin.

This document describes the features and characteristics of the CAT803, CAT809, and CAT810 3-pin microprocessor power supply supervisors from Catalyst Semiconductor, Inc. It includes precision monitoring of +5.0V, +3.3V, +3.0V, and +2.5V power supplies, three output configurations, direct replacements for MAX803, MAX809, and MAX810 products, and suitability for applications operating over the industrial temperature range.

The CAT1021, CAT1022 and CAT1023 are complete memory and supervisory solutions for microcontroller-based systems. A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS technology. Memory interface is via a 400kHz I2C bus. The CAT1021 and CAT1023 provide a precision VCC sense circuit and two open drain outputs: one (RESET) drives high and the other (RESET) drives low whenever VCC falls below the reset threshold voltage. The CAT1022 has only a RESET output and does not have a Write Protect input. The CAT1021 also has a Write Protect input (WP). Write operations are disabled if WP is connected to a logic high. All supervisors have a 1.6 second watchdog timer circuit that resets a system to a known state if software or a hardware glitch halts or “hangs” the system. For the CAT1021 and CAT1022, the watchdog timer monitors the SDA signal. The CAT1023 has a separate watchdog timer interrupt input pin, WDI.
