Characteristics subject to change without notice DESCRIPTION The CAT1024 and CAT1025 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 CAT1025 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 the reset threshold voltage. The CAT1025 also has a Write Protect input (WP). Write operations are disabled if WP is connected to a logic high. The CAT1024 also provides a precision VCC sense circuit, but has only a RESET output and does not have a Write Protect input. The power supply monitor and reset circuit protect memory and system controllers during power up/down and against brownout conditions. Five reset threshold Doc No. 3008, Rev. M voltages support 5V, 3.3V and 3V systems. If power supply voltages are out of tolerance reset signals become active, preventing the system microcontroller, ASIC or peripherals from operating. Reset signals become inactive typically 200 ms after the supply voltage exceeds the reset threshold level. With both active high and low reset signals, interface to microcontrollers and other ICs is simple. In addition, the RESET pin or a separate input, MR, can be used as an input for push-button manual reset capability. The CAT1024/25 memory features a 16-byte page. In addition, hardware data protection is provided by a VCC sense circuit that prevents writes to memory whenever VCC falls below the reset threshold or until VCC reaches the reset threshold during power up. Available packages include an 8-pin DIP, 8-pin SOIC, 8-pin TSSOP, 8-pin TDFN and 8-pin MSOP. The TDFN package thickness is 0.8mm maximum. TDFN footprint is 3x3mm.
