A EEPROM Serial 2-Kb CPU Supervisor and a system power supervisor with brown-out protection are integrated together in low power CMOS technology. Memory interface is via a 400 kHz I²C bus. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe CAT1023 provides a precision V\u003csub\u003eCC\u003c\/sub\u003e sense circuit and two open drain outputs: one (RESET) drives high and the other (\u003cspan class=\"overline\"\u003eRESET\u003c\/span\u003e) drives low whenever V\u003csub\u003eCC\u003c\/sub\u003e falls below the reset threshold voltage. Write operations are disabled if WP is connected to a logic high.\u003cbr\u003eThe supervisor has 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. The CAT1023 has a separate watchdog timer interrupt input pin, WDI.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe power supply monitor and reset circuit protect memory and system controllers during power up\/down and against brownout conditions. Five reset threshold voltages support 5.0 V, 3.3 V and 3.0 V 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 \u003cspan class=\"overline\"\u003eRESET\u003c\/span\u003e pin or a separate input, \u003cspan class=\"overline\"\u003eMR\u003c\/span\u003e, can be used as an input for push-button manual reset capability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe on-chip, 2k-bit EEPROM memory features a 16-byte page. In addition, hardware data protection is provided by a V\u003csub\u003eCC\u003c\/sub\u003e sense circuit that prevents writes to memory whenever V\u003csub\u003eCC\u003c\/sub\u003e falls below the reset threshold or until V\u003csub\u003eCC\u003c\/sub\u003e reaches the reset threshold during power up.\u003cbr\u003eAvailable 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 maxi.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eONS:CAT1023\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eCAT1023\u003c\/span\u003e\u003c\/p\u003e","brand":"onsemi","offers":[{"title":"Default Title","offer_id":43011652976839,"sku":"ONS:CAT1023","price":0.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2750\/0701\/products\/onsemi-eeprom-serial-2-kb-cpu-supervisor-part-cat1023-eeprom-dex-information-technology-onsemi-462263.jpg?v=1674082357","url":"https:\/\/edexdealstest.myshopify.com\/products\/onsemi-eeprom-serial-2-kb-cpu-supervisor-part-cat1023-eeprom-dex","provider":"DEX TEST","version":"1.0","type":"link"}
