X5083 CPU Supervisor with 8Kbit SPI EEPROM is a chip that integrates four popular functions (Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, Block Lock Serial EEPROM Memory) in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.
The X5083 combines power‑on reset, watchdog timer, supply‑voltage supervision, and a block‑lock 8‑Kbit serial EEPROM in a single IC. It provides four selectable reset‑threshold voltages, low standby current, and a 3.3 MHz SPI interface for easy integration with microcontrollers.
Typical applications include communications equipment, industrial systems, intelligent instrumentation, and battery‑powered devices. The device is offered in 8‑lead TSSOP, SOIC, and PDIP packages and complies with RoHS standards.
| Reset threshold voltages | 4.63 V, 4.38 V, 2.93 V, 2.63 V |
|---|---|
| Standby current (watchdog on) | <50 µA |
| Standby current (watchdog off) | <1 pA |
| Active current during read | <400 µA |
| EEPROM size | 8 Kbits |
| SPI clock rate | 3.3 MHz |
| Page write size | 16 bytes |
| Write cycle time (typical) | 5 ms |
| Available packages | 8‑LD TSSOP, 8‑LD SOIC, 8‑LD PDIP |
The standby current is less than 50 µA when the watchdog is on.
The device includes 8 Kbits of EEPROM memory.
The selectable thresholds are 4.63 V, 4.38 V, 2.93 V, and 2.63 V.
The SPI interface supports up to a 3.3 MHz clock rate.
