This datasheet describes the X5168 and X5169 CPU supervisors with 16Kbit SPI EEPROM, which combine power-on reset control, supply voltage supervision, and block lock protect serial EEPROM memory in one package.
Key Features
These devices offer low Vcc detection and reset assertion, with five standard reset threshold voltages that can be re-programmed using a special programming sequence. They also feature long battery life with low power consumption, 16Kbits of EEPROM, and built-in inadvertent write protection.
Operating Conditions
The devices operate from 2.7V to 5.5V and 4.5V to 5.5V, with available packages including 14 Ld TSSOP, 8 Ld SOIC, and 8 Ld PDIP, with Pb-Free Plus Anneal options.
The X5168 and X5169 are designed to provide a power-on reset circuit that holds the reset signal active during power-up, allowing the power supply and oscillator to stabilize before the processor can execute code. The devices also feature low Vcc detection circuitry that protects the system from low voltage conditions.
